    Chronic rhinitis is a very common disease, as the prevalence in the general population resulted to be 40%. Allergic rhinitis has been considered to be the most frequent form of chronic rhinitis, as non-allergic rhinitis has been estimated to account for 25%. However, several evidences suggested that non-allergic rhinitis have been underrated, especially in children. In pediatrics, the diagnostic definition of non-allergic rhinitis has been often limited to the exclusion of an allergic sensitization. Actually, local allergic rhinitis has been often misdiagnosed as well as mixed rhinitis has not been recognized in most cases. Nasal cytology is a diagnostic procedure being suitable for routine clinical practice with children and could be a very useful tool to characterize and diagnose non-allergic rhinitis, providing important clues for epidemiological analysis and clinical management.

    Full Text Available Abstract Background Traumatic paediatric arterial injuries are a great challenge due to low incidence and specific characteristics of paediatric anatomy and physiology. The aim of the present study was to investigate their epidemiology, diagnostic and therapeutic options and complications. Furthermore, the prognostic value of the Mangled Extremity Severity Score (MESS was evaluated. Methods In a retrospective clinical study 44 children aged 9.0 ± 3.2 years treated for traumatic extremity arterial lesions in our Level I trauma center between 1971 and 2006 were enrolled. Exclusion criteria were age > 14, venous and iatrogenic vascular injury. Demographic data, mechanism of injury, severity of arterial lesions (by Vollmar and MESS, diagnostic and therapeutic management, complications and outcome were evaluated. Results The most commonly injured vessel was the femoral artery (25% followed by the brachial artery (22.7%. The mechanism of injury was penetrating (31.8%, isolated severe blunt extremity trauma (29.6%, multiple trauma (25% and humeral supracondylar fractures (13.6%. In 63.6% no specific vascular diagnostic procedure was performed in favour of emergency surgery. Surgical reconstructive strategies were preferred (68.2%. A MESS Conclusions Traumatic paediatric vascular injuries are very rare. The most common situations of vascular lesions in childhood were penetrating injuries and fractures of the extremities either as isolated injuries or in multiply injured patients. In paediatric patients, the MESS could serve as a basis for decision making for limb salvage or amputation.

  4. Epidemiology and diagnostics of human fasciolosis

    Full Text Available Fasciolosis is a zoonotic infection caused by the trematoda Fasciola hepatica and Fasciola gigantica. Human fasciolosis is endemic in some parts of South America, Africa, Eastern Asia and Europe. High prevalence of human fasciolosis does not necessarily occur in areas where fasciolosis is a major veterinary problem. Infection with Fasciola hepatica has not been reported in humans in Serbia and former Yugoslavia, although a large variety of animals, such as sheep and cattle show infection rates that may reach significant proportions in some areas. Humans can become accidental hosts of this parasite by ingesting contaminated drinking water or plants in an endemic area. Infection with Fasciola hepatica has a variable clinical presentation depending on the stage of the disease. Typical symptoms that may be associated with fascioliasis can be divided by the phases of the disease including the acute or liver phase, the chronic or biliary phase, the obstructive phase, and ectopic or pharyngeal fascioliasis. The diagnosis of human fasciolosis may be problematical and delayed, especially in non-endemic areas, because physicians rarely encounter this disease and a long list of other diseases must be included in the differential diagnosis. The diagnosis of fasciolosis is complex and requires the application of direct an indirect methods of diagnostics: clinical diagnosis, haematological and biochemical findings, parasitological diagnosis, immuno-diagnosis, imaging procedures, liver biopsy. At the Clinic for Infectious and Tropical Diseases in 2005, we recorded the first case of human fasciolosis in a woman from Belgrade, a citizen of Serbia, who developed clinical symptoms of acute fasciolosis after several months of living in Bosnia-Herzegovina. This article reviews the epidemiology and diagnostics of human fasciolosis. .

    2011-10-01

    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.

    The severe pulmonary disease caused by the inhalation of the different Legionella species is called Legionella pneumonia, while the name of the pulmonary disease caused by the most common Legionella (L. pneumophila) is Legionnaires' disease. Another type of disease caused by legionellae is Pontiac fever with influenza-like symptoms. Legionella spp. are facultative intracellular parasites. They survive within both monocytes in the human organism and amebae in the environment. To prevent and control the occurrence of legionelloses, legionellae should be surveyed and detected in the environmental (water pipes, air-conditioning systems, cooling towers, respiratory equipments, etc.) and clinical (blood, bronchoalveolar lavage, sputum, abscess, etc.) samples. Laboratory diagnosis is complicated by the limitations of the available assays. Thus, it is proposed that the microbiological laboratory diagnosis should be based on the simultaneous application of at least three methods (culturing [on BCYE medium], followed by biochemical assays, serology, molecular biologic methods, such as polymerase chain reaction [PCR], direct demonstration [immunofluorescence microscopy], antigen determination are the most important ones) and on the simultaneous demonstration from three different samples (e.g. lower respiratory tract secretions, sputum, urine, blood culture, serum, moreover, water samples from all potential infectious sources, sediment of hot water tanks, as well as swab samples of faucets and shower heads). The advantage of PCR is that is gives reliable results in one day, in contrast to conventional culturing. However, its sensitivity can not be improved by increasing the sample volume, and neither can it give quantitative results nor can it produce strains for epidemiologic studies, contrary to the method of culturing. It is concluded that PCR and culturing do complement, but do not substitute each other.

    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.

    The epidemiological studies testify an extremely high prevalence of chronic infection of children with Helicobacter pylori in Russia. The affection consists from 50% to 80% depending on region and age of examined children. The currently in force recommendations "Maastricht IV" concerning diagnostic and treatment of Helicobacter pylori infection adult patients are applied not in its fullness to children adolescent population. At the same time recently published joint conciliatory document of the European and North American associations of pediatric gastroenterologists is oriented to populations with low prevalence of Helicobacter pylori infection and particular profile of drug resistance. Hence, an urgent need exists to develop modern local algorithm concerning diagnostic, treatment and control of eradication of Helicobacter pylori infection among children and adolescents in Russia. The review presents analysis of admissibility of application in Russia's conditions of the international conciliatory documents concerning diagnostic of Helicobacter pylori infection in children. The data from conciliatory document of the European (ESPGHAN) and North American (NASPGHAN) associations of pediatric gastroenterologists, particular orginal research studies and one's own clinical experience were used. The advantages and shortcomings of actual methods of laboratory diagnostic of Helicobacter pylori infection are discussed. The approaches to application of particular diagnostic methods are considered. The enhanced indications to detection of infection and implementation of eradication therapy are proposed.

    Full Text Available Unintentional drug intoxication is still a major cause of morbidity and mortality in young children. In order to study the epidemiological pattern of childhood drug poisoning in Golestan province, all cases diagnosed with poisoning from 1997 to 2002 in the only pediatric hospital in province were recruited. During this period 563 cases of poisoned children were hospitalized in Taleqani hospital, of these 305 cases were due to drug poisoning. Opium was responsible for more than half of the poisoning cases, and 91% of deaths, among drug intoxicated children. Metoclopramide, benzodiazepines, tricyclic antidepressants and anticonvulsants were among the other frequent causes of poisoning. Neurological symptoms were the most prominent symptoms of poisoning and more than 80% of cases showed some neurological symptoms. Mortality rate among the cases was 3.6% and of total of 11 deaths, 10 were poisoned with opium. About 61% of cases were hospitalized between 24-48 hrs. Most of the poisoning cases in young children were unintentional and in many cases, their parents played a critical role in their intoxication. This role specially is crucial in infants and children under one year of age. Parents in Golestan province use opium widely for symptomatic treatment of routine illnesses in their young children and overdose of opium may cause severe intoxication and even death of the child.

    Chikungunya virus (CHIKV) is an Aedes-borne alphavirus, historically found in Africa and Asia, where it caused sporadic outbreaks. In 2004, CHIKV reemerged in East Africa and spread globally to cause epidemics, including, for the first time, autochthonous transmission in Europe, the Middle East, and Oceania. The epidemic strains were of the East/Central/South African genotype. Strains of the Asian genotype of CHIKV continued to cause outbreaks in Asia and spread to Oceania and, in 2013, to the Americas. Acute disease, mainly comprising fever, rash, and arthralgia, was previously regarded as self-limiting; however, there is growing evidence of severe but rare manifestations, such as neurological disease. Furthermore, CHIKV appears to cause a significant burden of long-term morbidity due to persistent arthralgia. Diagnostic assays have advanced greatly in recent years, although there remains a need for simple, accurate, and affordable tests for the developing countries where CHIKV is most prevalent. This review focuses on recent important work on the epidemiology, clinical disease and diagnostics of CHIKV.

    Cryptosporidium, Giardia intestinalis, Cyclospora cayetanensis, Isosopra belli and micropsoridia are the most important and common pathogens found in humans and many other species of vertebrates. In humans, mainly in immunocompromised patients, children, pregnant women and elderly people, they are the most frequently identified protozoan parasites causing gastrointestinal disease worldwide. These pathogens have several transmission routes, including anthroponotic and zoonotic transmission. What is more, in many cases of epidemics caused by mentioned pathogens the major cause of infection was contaminated with these organisms water and food. In spite of many existing regulations of clearing and making use of drinking water supplies and recreational water, cosmopolitan protozoan parasites are still the danger of public health. These organisms are responsible for many waterborne outbreaks worldwide. Light microscopy and immunofluorescence assay have been used to identify these organisms in most laboratories. However, these traditional techniques have major limitations in the specific diagnosis, these methods are not sensitive enough to detect cysts or oocysts in environmental samples, so the new molecular tools must be applied. Recently, PCR-based techniques have been developed for detection and genetic characterization of the different species and population variants of protozoan parasites is central to the prevention, surveillance and control of gastrointestinal diseases. In this review were characterized biology, epidemiology and the progress in technology for detection and surveillance of the most important waterborne protozoan parasites.

    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.

    The growing use of interventional and fluoroscopic imaging in children represents a tremendous benefit for the diagnosis and treatment of benign conditions. Along with the increasing use and complexity of these procedures comes concern about the cancer risk associated with ionizing radiation exposure to children. Children are considerably more sensitive to the carcinogenic effects of ionizing radiation than adults, and children have a longer life expectancy in which to express risk. Numerous epidemiologic cohort studies of childhood exposure to radiation for treatment of benign diseases have demonstrated radiation-related risks of cancer of the thyroid, breast, brain and skin, as well as leukemia. Many fewer studies have evaluated cancer risk following diagnostic radiation exposure in children. Although radiation dose for a single procedure might be low, pediatric patients often receive repeated examinations over time to evaluate their conditions, which could result in relatively high cumulative doses. Several cohort studies of girls and young women subjected to multiple diagnostic radiation exposures have been informative about increased mortality from breast cancer with increasing radiation dose, and case-control studies of childhood leukemia and postnatal diagnostic radiation exposure have suggested increased risks with an increasing number of examinations. Only two long-term follow-up studies of cancer following cardiac catheterization in childhood have been conducted, and neither reported an overall increased risk of cancer. Most cancers can be induced by radiation, and a linear dose-response has been noted for most solid cancers. Risks of radiation-related cancer are greatest for those exposed early in life, and these risks appear to persist throughout life. (orig.)

    2008-10-01

    The objectives of this study were to (i) characterize epidemiologic trends in anterior permanent tooth trauma in a sample of children and adolescents (ii) examine the relationship of crown fractures (CF) and concomitant root fractures (RF) to determine if CFs are protective against RFs and (iii) examine the radiographic evidence of RFs to determine the value of obtaining three vertical periapical radiographic projections. This was an 8-year cross-sectional study of patients aged 6-18 with anterior permanent tooth trauma. We examined cases involving maxillary central/lateral incisors for which three clearly diagnostic periapical radiographs were obtained during the initial emergency visit. Two trained and calibrated dentists served as expert examiners for the radiographic assessments. Kappa statistics were used to determine reliability. Tests for association of concomitant crown and root fractures were performed using Likelihood Ratio Chi-Square tests. The final sample included 185 teeth in 114 children. Our demographic and epidemiologic findings were comparable to those of previous studies. Experts reached this consensus: 22 RFs were detected, 9.6% (eight out of 83) teeth exhibited root fractures when no CFs was documented, and 13.7% (14 out of 102) teeth had both CFs and RFs as separate entities. Good examiner reliability was reached confirming the presence of RFs (Kappa = 0.81). The association of concomitant RFs and CFs was odds ratio = 1.97 (P = 0.052). CFs were not protective against RFs; indeed, teeth with CFs were twice as likely to have an RF as those without CFs. As the number of radiographic projections increased, RFs were identified more often; however, our data suggest that there is no reason to suspect a complete RF in preteen children unless the root exhibits clinical signs such as luxation or severe mobility. This study provides solid evidence to support obtaining multiple radiographic projections at different vertical angulations to rule out RFs in

    SUMMARY We analysed Mycobacterium tuberculosis strains from children, hospitalized from January 2004 to July 2008 in the largest paediatric hospital complex in Cambodia. Specimens were tested for drug susceptibility and genotypes. From the 260 children, 161 strains were available. The East African-Indian genotype family was the most common (59.0%), increasing in frequency with distance from the Phnom Penh area, while the frequency of the Beijing genotype family strains decreased. The drug resistance pattern showed a similar geographical gradient: lowest in the northwest (4.6%), intermediate in the central (17.1%), and highest in the southeastern (30.8%) parts of the country. Three children (1.9%) had multidrug-resistant tuberculosis. The Beijing genotype and streptomycin resistance were significantly associated (P tuberculosis in children reflects recent transmission patterns in the community, multidrug resistance levels inform about the current quality of the tuberculosis programme.

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.

    Type 1 diabetes is one of the most common chronic diseases of childhood and adolescence. Multiple registries have assessed its epidemiology and have noted a steady increase in incidence of the disease. This article addresses the epidemiology of type 1 diabetes in children aged 0 to 19 years, by reviewing the available, current data from both US and international registries. The prevalence and incidence data by race, ethnicity, age of onset, sex, season of onset, and temporal trends of the disease are presented. Multiple risk factors have been implicated for the increasing incidence in type 1 diabetes, and these genetic and environmental risk factors are discussed.

    Hemochromatosis is the most common genetic disease in northern European populations. Body iron stores progressively increase in most patients, which can lead to cirrhosis of the liver, hepatocellular carcinoma, heart failure, arthritis, and pigmentation. Simple blood tests such as the serum ferritin and transferrin saturation are useful to suggest the diagnosis which can be confirmed in most cases with a simple genetic test for the C282Y mutation of the HFE gene. However, these blood tests are often misinterpreted and there are rare patients with iron overload without HFE mutations. A diagnostic approach is presented based on a large referral practice and a population-based study (HEIRS) which screened for iron overload in 101,168 participants.

    Parasomnias are a group of disorders exclusive to sleep and wake-to-sleep transition that encompass arousals with abnormal motor, behavioral, or sensory experiences. Sensory experiences often involve but are not limited to perceptions, dreamlike hallucinatory experiences, and autonomic symptoms. When accompanied with excessive motoric activity and other complex motor behaviors, these parasomnnias can be disruptive to the patient and bed partners. Motor behaviors may or may not be restricted to bed but can become dangerous when the subject ambulates or is agitated. The behaviors are inappropriate for the time of occurrence but may seem purposeful or goal directed. Most parasomnias are more common in children and decrease in frequency as they get older. Parasomnias have been reported in approximately 4% of the adult population.

    High blood pressure (BP) still remains one of the most relevant cardiovascular risk factors, also due to its persistently high prevalence and growing incidence in the general adult and elderly population. Since almost all hypertension-related cardiovascular complications, mostly including coronary artery disease, myocardial infarction, ischemic stroke, and congestive heart failure, occurred in adult and elderly individuals, evidence on both prevalence and clinical management of hypertension in young individuals are lacking. Therefore, the clinical impact of high BP levels in young populations remains to be explored. In the recent years, the attitude of the scientific community has changed and more attention was devoted to young individuals with hypertension, also in view of the fact that early identification of these subjects may prevent developing of established hypertension in adulthood. In addition, unhealthy lifestyle habits have progressively involved children and adolescents worldwide, thus contributing to further increase the risk of developing hypertension in young individuals. On the basis of these considerations, the present review is aimed at providing a brief reappraisal of the major aspects of hypertension in the young age, as well as at promoting interest and discussion on this important issue.

    Among 49 000 cases of infantile emergencies which were received in the BUCI (Bloc d'urgence chirurgical infantile: surgical infantile emergency unit), 5 546 were sport traumas. At an early age, they were caused by outdoor plays; during adolescence, the main cases were caused by team sports. Males are predominant. The number of cases has been regularly progressing, particularly since 1976. The fashion in sports is influenced by médias (i.e. skate board), and can be opposed to the continuous practice of popular sports (swimming, ball games, bycicle. There are winter, summer, school timed sports (the latter being influenced by the sportive scholar associations). The most frequent sports are cycling, football playing, swimming and horse riding, athleticism skating, Other are occasionnal. Changes in sport fashions, female increasing participation, such as horse riding and skating, democratisation (skiing, riding), the worsening of traumas; the pathology concerning bystanders, are described. Cranial and peripheric pathology are dominant. Trunk traumas are scarce but severe. Each sport has an elective pathologic localisation. Injury mechanisms are found, such as stirrup, saddle, ski baton pathology. There is traumatologic similarities; skate board and roller skating; judo and atheleticism; cycling and horse riding. Sport in children is not a replica of the one among adults. Riding a bike is not cycling. Some sports are dangerous: cycling, horse riding, rugby. A traumatological outline is revealed. Preventive measures should be taken. The socio-economical cost is heavy.

    Full Text Available In the paper the results of an epidemiological study conducted in 2010-2011 as a part of the regional project Balkan Epidemiological Study on Child Abuse and Neglect (BECAN are presented. 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%.

    Dentists who treat children must be alert to the possibility of finding diseases of the oral mucosa, especially in younger children. The present study aimed to review the most updated information and the experience of our group in order to yield epidemiological data that assist diagnosis of the most common diseases of the oral mucosa in children. Recent epidemiologic studies have shown a wide variability in the prevalence of oral mucosal lesions in different regions of the world and have led researchers to draw disparate conclusions. Moreover, studies have not been designed using standard criteria, further explaining the wide variability in the percentage of different groups of children with oral lesions, which ranges from 4.1 to 52.6%. The lesions most frequently considered by authors and that most often appear in the different studies are: recurrent aphthous stomatitis (0.9-10.8%), labial herpes (0.78-5.2%), fissured tongue (1.49-23%), geographic tongue (0.60-9.8%), oral candidiasis (0.01-37%) and traumatic injury (0.09%-22.15%). Dentists must be able to detect any of the numerous possible disorders and perform the correct differential diagnosis, key to the treatment plan. The aim of this paper, based on a review of the different national and international studies, is to contribute data on the most important oral mucosal diseases in the paediatric population in terms of prevalence and differential diagnosis.

    There has been an extensive body of research focusing on the epidemiology of thrombosis in adult cancer populations; however, there is significantly less knowledge about thrombosis in paediatric cancer populations. Thrombosis is diagnosed with increasing frequency in children being treated for cancer, and there is an urgent need to increase our understanding of the epidemiology of thrombosis in this population. Currently, there are no guidelines for identification of high-risk groups, prophylaxis or management of thrombotic complications in paediatric cancer patients. We reviewed the available literature regarding the epidemiology, mechanisms, risk factors, prophylaxis and outcomes of thrombosis in children with cancer and identified areas that require further research. The reported incidence of symptomatic venous thromboembolism (VTE) in children with cancer ranges between 2.1% and 16%, while the incidence of asymptomatic events is approximately 40%. Approximately 30% of VTE in this population is associated with central venous lines (CVL). The most common location of VTE is upper and lower extremity deep venous thrombosis (43 to 50% of events, respectively), while 50% of events in ALL patients occur in the central nervous system. Key characteristics that increase the risk of thrombosis include the type of cancer, age of the patient, the presence of a CVL, presence of pulmonary/intra thoracic disease, as well as the type of chemotherapy. Outcomes for paediatric cancer patients with VTE include post-thrombotic syndrome, pulmonary embolism, recurrent thromboembolism, destruction of upper venous system and death. Prospective studies aimed at enabling risk stratification of patients are required to facilitate development of paediatric specific recommendations related to thromboprophylaxis in this population.

    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.

    2015-03-01

    Since 1st January 2000, the PEDIAB-LR registry has listed new cases of diabetes in children under 16 years of age in the Languedoc-Roussillon region of France, in order to assess the incidence and epidemiological characteristics of children affected by diabetes. At the end of December 2010, 745 children had been registered. The characteristics of these children included an identical proportion of girls and boys, a mean age of 8 years at diagnosis, and a family history of type 1 diabetes in 8.4% of the cases. Inaugural ketoacidosis was observed in 69.5% of the patients and was severe in 23.7% of these cases. To replace intravenous insulin, a two-injection dosing regimen (in the morning and before dinner) was prescribed in 76.5% of cases, multi-injections of basal-bolus in 16%, and subcutaneous insulin infusion (insulin pump therapy) in 7.5% of cases. Between 2000 and 2010, there was no increase in overall incidence. It is noteworthy that age at diagnosis tended to decrease, but this was not statistically significant. In conclusion, the PEDIAB-LR registry is currently the only French registry on diabetes in children, analyzing many factors related to its incidence, such as age at diagnosis and the existence of ketoacidosis.

  2. Post-mortem diagnostics in cases of sepsis. Part 1. Aetiology, epidemiology and microbiological tests

    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.

    Full Text Available Background: chronic adenoiditis, which causes the greater number of elective major surgeries in children, is a common disease in Cuba. Objectives to describe the clinical and epidemiological characteristics of chronic adenoiditis in children. Methods: a descriptive study with non-probability sampling was conducted in 98 children with chronic adenoiditis treated at the University Pediatric Hospital of Central Havana, between September 2009 and July 2011. The variables analyzed were age, sex, symptoms, signs and main clinical manifestations, personal medical history, family history, and major environmental and social risk factors. A survey was conducted to identify risk factors. Statistical analysis such as: the mean, relative frequency and frequency tables were performed. Results: highest morbidity was observed in children aged 1 to 9 years. The main features of the disease were nasal obstruction, dental malocclusion, mouth breathing and respiratory infection. The most common risk factors were attendance to day-care centers and exposure to cigarette smoke. Personal and family history of asthma and respiratory allergies was the most frequently found. Conclusion: chronic adenoiditis in pediatric patients is multifactorial in origin, and tends to decrease in the child population older than nine years.

    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

    Meningitis with a negative cerebrospinal fluid Gram stain (CSF-GS) poses a diagnostic challenge as more than 50% of patients remain without an aetiology. The introduction of polymerase chain reaction (PCR) and arboviral serologies have increased diagnostic capabilities, yet large scale epidemiological studies evaluating their use in clinical practice are lacking. We conducted a prospective observational study in New Orleans between November 1999 and September 2008 (early era) when PCR was not widely available, and in Houston between November 2008 and June 2013 (modern era), when PCR was commonly used. Patients presenting with meningitis and negative CSF-GS were followed for 4 weeks. All investigations, PCR used, and results were recorded as they became available. In 323 patients enrolled, PCR provided the highest diagnostic yield (24·2%) but was ordered for 128 (39·6%) patients; followed by serology for arboviruses (15%) that was ordered for 100 (31%) of all patients. The yield of blood cultures was (10·3%) and that of CSF cultures was 4%; the yield for all other tests was viral pathogens, 8·3% and 26·3% (P meningitis and a negative CSF-GS, but both tests are being under-utilized.

    Epidemiologic data on chronic inflammatory demyelinating polyneuropathy (CIDP) is limited, and previous studies have shown variable results. The frequencies of CIDP subtypes remain unknown. Variations due to use of different diagnostic criteria have not been studied. We examined the prevalence and incidence of CIDP in Leicestershire and Rutland, UK (population 963,600). Prevalence day was 1 May 2008. The prevalence of CIDP fulfilling the 2006 clinical and electrophysiologic European Federation of Neurological Societies/Peripheral Nerve Society (EFNS/PNS) criteria was 4.77 per 100,000 (95% confidence interval [CI] 3.49-6.37). Using the 1991 American Academy of Neurology (AAN) criteria, the prevalence was 1.97 per 100,000 in this population (95% CI 1.19-3.08). Lewis-Sumner syndrome was diagnosed in 15.2% of patients, and 23.9% had pure sensory onset. Over 40% required no immunotherapy, and 84.6% of those treated responded. More than 80% of the AAN criteria-negative but EFNS/PNS criteria-positive patients were responsive to treatment. Both sets of criteria were equally likely to identify patients who required therapy. The mean annual incidence rate over the 3 years preceding the prevalence day was 0.70 per 100,000/year using EFNS/PNS criteria (95% CI 0.43-1.08), and 0.35 per 100,000/year using AAN criteria (95% CI 0.17-0.64). We conclude that the AAN criteria may underestimate prevalence and incidence of the disease. The EFNS/PNS criteria provide higher diagnostic sensitivity and are of greater clinical relevance, and they also offer a useful breakdown of the epidemiologic data for CIDP subtypes.

    1998-11-01

    An electrocardiographic recording method with an associated reading guide, designed for epidemiological studies on Chagas' disease, was tested to assess its diagnostic reproducibility. Six cardiologists from five countries each read 100 electrocardiographic (ECG) tracings, including 30 from chronic chagasic patients, then reread them after an interval of 6 months. The readings were blind, with the tracings numbered randomly for the first reading and renumbered randomly for the second reading. The physicians, all experienced in interpreting ECGs from chagasic patients, followed printed instructions for reading the tracings. Reproducibility of the readings was evaluated using the kappa (kappa) index for concordance. The results showed a high degree of interobserver concordance with respect to the diagnosis of normal vs. abnormal tracings (kappa = 0.66; SE 0.02). While the interpretations of some categories of ECG abnormalities were highly reproducible, others, especially those having a low prevalence, showed lower levels of concordance. Intraobserver concordance was uniformly higher than interobserver concordance. The findings of this study justify the use by specialists of the recording of readings method proposed for epidemiological studies on Chagas' disease, but warrant caution in the interpretation of some categories of electrocardiographic alterations.

    The dog is the natural host of Staphylococcus pseudintermedius. Many research efforts are currently being undertaken to expand our knowledge and understanding of this important canine commensal and opportunistic pathogen. The objective of this review is to summarize the current knowledge of the species, including the latest research outcomes, with emphasis on taxonomy, diagnostics, ecology, epidemiology and pathogenicity. Despite the important taxonomic changes that have occurred over the past few years, the risk of misidentification in canine specimens is low and does not have serious consequences for clinical practice. Staphylococcus pseudintermedius carriage in the dog is more frequent and genetically heterogeneous compared with that of Staphylococcus aureus in man. It appears that these staphylococcal species have evolved separately through adaptation to their respective natural hosts and differ with regard to various aspects concerning ecology, population structure and evolution of antibiotic resistance. Further understanding of the ecology and epidemiology of S. pseudintermedius is hampered by the lack of a standard method for rapid and discriminatory typing and by the limited data available on longitudinal carriage and population structure of meticillin-susceptible strains. With regard to pathogenicity, it is only now that we are starting to explore the virulence potential of S. pseudintermedius based on genomic and proteomic approaches, and more research is needed to assess the importance of individual virulence factors and the possible existence of hypervirulent strains.

    Canine parvovirus type 2 (CPV-2) emerged in late 1970s causing severe epizootics in kennels and dog shelters worldwide. Soon after its emergence, CPV-2 underwent genetic evolution giving rise consecutively to two antigenic variants, CPV-2a and CPV-2b that replaced progressively the original type. In 2000, a new antigenic variant, CPV-2c, was detected in Italy and rapidly spread to several countries. In comparison to the original type CPV-2, the antigenic variants display increased pathogenicity in dogs and extended host range, being able to infect and cause disease in cats. Epidemiological survey indicate that the newest type CPV-2c is becoming prevalent in different geographic regions and is often associated to severe disease in adult dogs and also in dogs that have completed the vaccination protocols. However, the primary cause of failure of CPV vaccination is interference by maternally derived immunity. Diagnosis of CPV infection by traditional methods has been shown to be poorly sensitive, especially in the late stages of infections. New diagnostic approaches based on molecular methods have been developed for sensitive detection of CPV in clinical samples and rapid characterisation of the viral type. Continuous surveillance will help assess whether there is a real need to update currently available vaccines and diagnostic tests.

    1990-01-01

    In order to investigate the diagnostic value of ultrasound in children with recurrent abdominal pain and to estimate the clinical relevance of rare organic causes of abdominal pain in these patients, we prospectively examined 93 children aged between 5.5 and 12 years by means of abdominal ultrasound. In 3 patients (3.2%) an anatomic abnormality was detected, which could not account for the abdominal pain. We conclude that many organic abnormalities, that could be diagnosed by ultrasound, are clinically irrelevant as a cause of recurrent abdominal pain in children and therefore ultrasound does not significantly contribute to the diagnosis. However, ultrasound can still play a role in the work-up of children with recurrent abdominal pain in avoiding unnecessary radiologic X-ray procedures.

    Objective: To determine brucellosis's epidemiologic, laboratory, diagnostic and public health features considering brucellosis is endemic in Azna County, western Iran. Methods: This descriptive cross-sectional study was investigated on 43 patients with brucellosis in Azna County. The subjects were the patients with symptoms correspondent with brucellosis and positive Wright and 2ME tests. A questionnaire about demographic, epidemiological and laboratory findings was filled in. Afterwards, patients were treated using usual antimicrobial drugs regimen. The collected data were analyzed by SPSS software version 16. Results:Forty-three subjects were found to be positive in laboratory tests. Incidence of Brucellosis was 59.31 per hundred thousand population. About 34.9% of patients were female and 65.1% male. Nearly 95.2 % of human cases were living in rural and 4.8 % in urban areas. Around 20.9% of patients had history of animal contact. The commonest transmission was unpasteurized dairy products (79.1%). The most contagious seasons were summer and spring (60.3%). The most common age group was 15-24 (27.9%), and about 60.5% of the patients were between 15-44 years old. Disease was more common among housewives (30.2%) and farmers (20.9%). The majority of the patients had Wright test titre=1:320 (54.1%) and 2ME test titre=1:160 (56.1%) in serological titration. Doxycycline with Rifampin was used for treatment of the greatest of patients (60.4%). Conclusions:In order to control this zoonotic disease, close cooperation of health and veterinary organizations is necessary.

    Full Text Available Aim of the study was to keep a real and actual photo relating to 2005-2008 regarding to diagnostic techniques and methodologies for intestinal parasites; so it would be possible to know specific epidemiology and suggest more rational and efficacious guide-lines. All members of AMCLI were involved in the proposal of a retrospective study regarding bowel parasites, helminths and protozoa.To engaged laboratories we asked how O&P was performed, if a specifical research for E. vermicularis and S. stercoralis was performed, if for the identification of D. fragilis, Entamoeba histolytica/dispar and Cryptosporidum spp were performed recommended specific permanent stains. 23 laboratories gave assent; but for an inferior number was possible to use the data for analysis and evaluation. Relating O&P only some laboratories performed permanent stains: Giemsa for D. fragilis, antigen and/or Trichrome stain for E. histolytica/dispar, antigen and/or acid fast stain for Cryptosporidium spp.Not all laboratories research specifically S. stercoralis. So the epidemiology is differentiated and related more to adequate or not adequate techniques than cohorts of examined populations. The overall positivity for parasites ranged from 0% to18.7%,for protozoa (pathogens or not were from 0% to 14.7%; for nematodes from 0% to 3.7%; for cestodes from 0% to 1.0%; for trematodes from 0% to 1.0%.Among helminths, E. vermicularis, followed by S. stercoralis, also in O&P, is the most frequent.The specific research of S. stercoralis gave a positivity from 0% to 33.3%; the cellophane tape test was positive for E. vermicularis from 0% fo 21.9% of cases.Among pathogen protozoa, D. fragilis, when permanent stain were applied, prevailed from 0% to 16.6%; G. duodenalis from 0.8% to 4.3%; E. histolytica/dispar, using a permanent stain or research of antigen, was identified from 0% to 20.6%. Coccidia were very rare, with Cryptosporidium spp observed from 0% to 5.2%. These are our conclusions

    Marcos André Aleixo

    2015-06-01

    Full Text Available Fasciola hepatica is a parasite that is located in the liver of ruminants with the possibility to infect horses, pigs and humans. The parasite belongs to the Trematoda class, and it is the agent causing the disease called fasciolosis. This disease occurs mainly in temperate regions where climate favors the development of the organism. These conditions must facilitate the development of the intermediate host, the snail of the genus Lymnaea. The infection in domestic animals can lead to decrease in production and control is made by using triclabendazole. Triclabendazole resistance in F. hepatica has been reported worldwide including in Brazil. Another concern is the increase number of human cases with the consumption of contaminated vegetables in regions where sanitation is inadequate together with the presence of infected animals and the absence of efficient control methods. The knowledge of the epidemiology of animal fasciolosis, including their occurrence, distribution and monitoring with techniques such as PCR and ELISA is reaching a new level with the usage of the Geographic Information System. The objective is to use new technologies for early fasciolosis diagnostic, as well as, to develop geoprocessing technics that could allow the determination of its prevalence and the evolution of clinical cases in animals before hand. This review paper provides an overview of F. hepatica, covering the aspects listed above, including original data.

    2013-09-01

    Rickettsioses are a group of zoonotic diseases caused by strict intracellular bacteria of the genus Rickettsia and Orientia which belong to the Rickettsiaceae family. Their ecology is influenced by environmental factors and the presence of specific vectors that determine the establishment and epidemiology in different world regions. In America, during the 20 th century, only three of these diseases were recognized: Rocky Mountain spotted fever, epidemic typhus and endemic typhus. However, since 2000, more than 10 different species that had previously been unknown in this continent have been described, both in arthropods and in clinical cases, fact that classifies them as emerging and re-emerging diseases. Given the clinical manifestations of the diseases caused by rickettsias, being the majority unspecific and, therefore, shared with other infectious diseases, especially viral and bacterial, they have been framed within the differential diagnoses of acute febrile syndrome in urban and tropical areas. Nowadays, there are direct and indirect diagnostic methods, which are useful in the definition of the infectious agent, in this case, the cause of rickettsioses.

    The clinical and epidemiological patterns as well as the results of the laboratory verification of the outbreak of enterovirus infection (EVI) in Minsk during the period of summer-autumn, 2000, are presented. During this outbreak a variety of clinical forms were observed, the serous meningitis being prevalent (57.5%). Practically simultaneous occurrence of infection on the territory of all administrative districts of the city, the predominant involvement of children aged up to 14 years into the outbreak, a high proportion of simultaneous casualities in the multiple foci. A number of circulating enteroviruses (EV)--ECHO 30, ECHO 6 of three serotypes and Coxsackie B5--were simultaneously isolated from clinical material. EV of the same serotypes were isolated from tap drinking water, and neutralizing antibodies to these serotypes were often detected in the patients blood sera. Infectious EV were also present in samples of bottled water and in water reservoirs used for bathing. The routes of EV transmission and the improvement of EVI control are discussed.

    Polycystic ovary syndrome (PCOS) is an endocrine syndrome with variable phenotypic expression and important systemic associations and sequelae, including obesity, insulin resistance, infertility, risk of endometrial cancer, and possible risk of cardiovascular events. PCOS is recognized as a condition influenced by genetic and environmental factors and distinct manifestations in all stages of life, including the prenatal period, childhood, adolescence, and adulthood. Identification of this disorder in childhood and adolescence has received growing attention, in part because of emerging evidence of the benefit of early intervention, but the diagnosis and management of PCOS in children and adolescents can be challenging. Diagnostic and therapeutic considerations of PCOS in children are reviewed to enhance identification and evaluation of patients suspected of having this disorder. When a diagnosis of PCOS is suspected in a child but cannot be confirmed, a provisional diagnosis is strongly recommended so as to prompt ongoing monitoring with an emphasis on important early interventions such as obesity reduction.

    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.

    Background.  Human rhinoviruses (HRVs) are frequently detected in children with acute respiratory illnesses (ARIs) but also in asymptomatic children. We compared features of ARI with HRV species (A, B, C) and determined genotypes associated with repeated HRV detections within individuals. Methods.  We used clinical data and respiratory samples obtained from children decreased appetite, and malaise were significantly higher in children with HRV-B. When codetections with other viruses were excluded (n = 155), these trends persisted, but some did not reach statistical significance. When 58 paired sequential HRV detections during asymptomatic and ARI episodes were sequenced, only 9 (16%) were identical genotypes of HRV. Conclusions.  Clinical features may differ among HRV species. Repeated HRV detections in young children frequently represented acquisition of new HRV strains.

    Information on the characteristics of children with limb deficiencies and amputations in The Netherlands is largely lacking. The present study aimed to collect data about the prevalence of congenital deficiencies, the ratio of congenital to acquired limb deficiencies, types of lower leg deficiency or amputation and male/female ratios. Data were obtained from a regional birth defects registry for the northern part of The Netherlands (EUROCAT-NNL) and from a national survey. Inclusion criteria for the selection of the EUROCAT data were: children/foetuses with lower leg deficiencies born in 1981-1986. Inclusion criteria for the survey data were: children aged 1-18 years with congenital deficiencies or acquired amputations of the leg, excluding toe deficiencies/amputations. Both the regional birth defects registry and the national survey only yielded small numbers of children, which limits the validity of the authors' findings. The Eurocat data show a prevalence of lower leg deficiencies at birth of 2.07/10,000. Fifty-five (55) children/foetuses were included in the present study. The male/female ratio was 1:1. Of the live-born children, 30% also had defects of the upper limbs, while 38% had bilateral lower limb deficiencies. The national survey included 89 children, of whom 73% had congenital deficiencies, while the others had undergone amputations: of which 37% were due to malignancies, 29% to traumata, 13% to infections and 21% to other pathology. The male/female ratio was 7:3 for the children with congenital deficiencies versus 6:4 for the children with acquired amputations. In the group of congenital deficiencies, fibula deficiency was most frequently seen (36%), while in the group with acquired amputations trans-femoral amputation, knee disarticulation and trans-tibial amputation were seen with equal frequency (21%). In 40% of the children with congenital deficiency and in 8% of the children with acquired amputations the arm was also affected. Both legs were

  14. Epidemiology of bladder stone of children: precipitating events.

    Science.gov (United States)

    Halstead, Scott B

    2016-04-01

    Urological surgery evolved from the ancient practice of removing primary bladder stones from young boys. Bladder stones, once ubiquitous, long ago disappeared from the developed world while pockets of disease still exist in developing countries. Two epidemiological studies identified as precipitating events of bladder stone formation the practice of substitutive carbohydrate feedings to newborns. In Southeast Asia, masticated rice is fed to newborns in stone-endemic villages while in England, during the eighteenth and nineteenth centuries pap or panada was used to hand-feed infants when breast milk was not available. Fresh milk from dairy animals was deemed preferable to pap. Lack of access to dairy cattle enhanced need for hand-feeding. In an epidemiological study, during mid-nineteenth century in England the prevalence of dairy cattle was inversely related to the prevalence of bladder stones. These epidemiological data relate stone formation to nutrition during the first few days or weeks of life. It is surmised that frequent use of or exclusive reliance on carbohydrate foods replacing milk feedings leads to a relative dietary deficiency in phosphates and the formation of insoluble urinary salts. Girls, with short, nontortuous urethras may pass much of the calculus debris without retaining nuclei in the bladder. In some males, stone nuclei are formed and retained. The growth of stones is determined thereafter by the net effect of depository and resorptive mechanisms operating over time distributing over many years the age that patients present for surgical stone removal. The role of early introduction of carbohydrate foods and reduced milk intake of neonates has not been incorporated into recommendations for feeding newborns in endemic countries nor comprehensively modeled in animals.

    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.)

    Increased public awareness of autism spectrum disorders (ASD) and routine screening in primary care have contributed to increased requests for diagnostic ASD evaluations. However, given the scarcity of subspecialty autism diagnostic resources, overreferral of children suspected of having ASD may be contributing to long waiting lists at tertiary care autism centers and delaying diagnosis for those children who truly have ASD. To determine whether children are being excessively referred to ASD-specific diagnostic clinics, our objective was to determine the prevalence of true ASD diagnoses in children referred for diagnostic ASD evaluation. Charts of all patients referred to a regional autism center between April 2011 and August 2012 for suspicion of a possible ASD were retrospectively reviewed and demographic and clinical diagnoses abstracted. Only 214 of 348 patients evaluated (61%) received an ASD diagnosis. Thus, concerns about autism are not confirmed by an ASD diagnosis in a significant number of children.

    2007-08-01

    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

    Background The bronchodilator response (BDR) reflects the reversibility of airflow obstruction and is recommended as an adjunctive test to diagnose asthma. The validity of the commonly used definition of BDR, a 12% or greater change in FEV1 from baseline, has been questioned in childhood. Objectives We sought to examine the diagnostic accuracy of the BDR test by using 3 large pediatric cohorts. Methods Cases include 1041 children with mild-to-moderate asthma from the Childhood Asthma Management Program. Control subjects (nonasthmatic and nonwheezing) were chosen from Project Viva and Home Allergens, 2 population-based pediatric cohorts. Receiver operating characteristic curves were constructed, and areas under the curve were calculated for different BDR cutoffs. Results A total of 1041 cases (59.7% male; mean age, 8.9 ± 2.1 years) and 250 control subjects (46.8% male; mean age, 8.7 ± 1.7 years) were analyzed, with mean BDRs of 10.7% ± 10.2% and 2.7% ± 8.4%, respectively. The BDR test differentiated asthmatic patients from nonasthmatic patients with a moderate accuracy (area under the curve, 73.3%). Despite good specificity, a cutoff of 12% was associated with poor sensitivity (35.6%). A cutoff of less than 8% performed significantly better than a cutoff of 12% (P = .03, 8% vs 12%). Conclusions Our findings highlight the poor sensitivity associated with the commonly used 12% cutoff for BDR. Although our data show that a threshold of less than 8% performs better than 12%, given the variability of this test in children, we conclude that it might be not be appropriate to choose a specific BDR cutoff as a criterion for the diagnosis of asthma.

    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.

    Enuresis is a very common developmental problem in young children. The aims of this study were to estimate the prevalence of enuresis in school-age children, to determine the factors associated with nocturnal enuresis, and to evaluate the parental strategies for managing enuresis. A randomly selected cross-sectional population-based study was conducted in eight elementary schools in Bangkok, Thailand. A total of 3453 parents of children aged 5 through 15 years completed the questionnaires. The overall response rate to the questionnaire was 70%. The prevalence of enuresis was 4.2% and that of nocturnal enuresis was 3.9%. The prevalence declined with increasing age from 10%, 5.3%, 3%, and 1.2% at ages 5, 7, 10, and 12 years, respectively. There was no enuretic child at ages 13 through 15 years. The prevalence of bed-wetting was slightly more frequent in females than males. Nocturnal enuresis was also found to be significantly associated with the history of encopresis and positive family history of enuresis. There was no significant associated with parental education, birth order, socioeconomic status, diaper use, toilet training, and behavioral and school problems. Behavioral techniques mostly used by parents for management of their children with bed-wetting were ensuring that the child voids before bedtime (72.9%), waking the child up at night to void (61.8%), and evening water intake restriction (28.5%). The overall prevalence rate of nocturnal enuresis in Bangkok school-age children is lower than that of many previous studies reported from other countries. The significant differences in the prevalence reported by other countries' studies attributed to the criteria selection for ranges of age, definition of enuresis, genetic predisposition, and traditional and cultural background.

    Rhinosinusitis (RS) is a significant health problem both in children and adult. A growing interest in RS resulted in two documents of European Position Paper on Rhinosinusitis and Nasal Polyps group (EPOS). This consensus offers evidence-based recommendations on diagnosis and treatment of RS and is intended to be a state-of- the art review for the specialists as well as the general practitioners.The recommendations divide rhinosinusitis as follows: acute viral or acute bacterial, recurrent and chronic RS. The symptoms of acute RS may increase after 5 day or persist after 10 days with less than 12 weeks duration. In recurrent RS there are about 6 episodes of acute RS during one year. Chronic RS is likely when symptoms of RS persist for longer than 12 weeks. Treatment of common cold is only symptomatic, while antibiotics and/or nasal steroids are recommended in severe acute RS. Endoscopic sinus surgery is indicated in chronic RS only when medical treatment fails and optimal medical treatment should always be continued after surgery. The computer tomography is the gold standard for diagnostics in cases of complication of RS or planning functional endoscopic sinus surgery (FESS).

    The study of 259 children in primary school revealed a prevalence of dysphonia of 10%, often undiagnosed, untreated or considered as benign. It would seem desirable to draw attention to this symptom, which may be an indication of organic pathology or of psychological problems, the early treatment of which may avoid later sequelae. It is sometimes necessary to allow a period for reflection in order to gain the cooperation of the child and his parents.

    Objective: In clinical structured diagnostic interviews, diagnoses based on parent and child reports have low to moderate agreement. The aims of the present study are (1) to examine diagnostic agreement on anxiety disorders between parents and children on the levels of current and lifetime diagnostic category and diagnoses focusing in particular on diagnostic criteria and (2) to identify parent- and child-related predictors for diagnostic agreement. Method: The sample consisted of 166 parent-child dyads interviewed with the Structured Diagnostic Interview for Mental Disorders in Children (Kinder-DIPS, Schneider et al., 2009). The children (51.8% girls) were between the ages of 7 and 18 years (M = 10.94; SD = 2.22). Results: Overall, parent-child agreement on the diagnostic category of anxiety disorder (k = 0.21; k = 0.22) and the specific anxiety diagnoses (base rate > 10%) of social phobia, specific phobia and separation anxiety disorder (k = 0.24–0.52; k = 0.19–0.43) and corresponding diagnostic criteria (k = 0.22–0.67; k = 0.24–0.41) were low to moderate with the highest agreement on separation anxiety disorder (k > 0.43). Lower maternal depression, and higher social support reported by mother and father were associated with higher parent-child agreement. Maternal depression was indicated as the strongest predictor. Parental sense of competence, parental anxiety, the amount of parent-child interaction and the child's age and gender had no predictive value. Conclusions: Parent-child agreement can be expected to be higher on the level of anxiety criteria compared to specific anxiety diagnoses and diagnostic anxiety category. Psychological strains in the family—especially maternal depression and low social support—lower the parent-child agreement on anxiety symptoms. Child- and relation-related variables (age, gender, amount of time parent(s) and children interact) play no role in the prediction of low parent-child agreement.

    2016-01-01

    Abstract From an epidemiological point of view, hepatitis E is an old infection in Iran, but only recently has its importance as a public health concern been considered from research and public health standpoints. As such, there is still a long road ahead to clarify the real burden of hepatitis E virus (HEV) infection in Iran. According to the available epidemiological studies, the seroprevalence of HEV infection among pregnant women is between 3.6% and 7.4%, and among Iranian children is between 0.9% to 8.5%, varying by geographic regions within the country and directly dependent upon the sanitary status of each. In addition to evaluating the sanitation level of a society, community-based seroprevalence studies of HEV infection demonstrate the most prevalent risk factors, the major routes of transmission, and the epidemiological patterns of HEV among that country’s population. In this review, the current knowledge about the pathogenesis and epidemiology of HEV infection in pregnant women and children in Iran, as well as the recent advances in diagnosis, prevention and treatment of HEV infection have been summarized.

    2015-01-01

    Large-scale food poisoning caused by methylmercury was identified in Minamata, Japan, in the 1950s (Minamata Disease). Although the diagnostic criteria for the disease was controversial and difficult during that time, we, the Kumamoto University Study Group, carried out a large-scale study to assess the clinical features in 1972-1973. The author tried to reassess the results of that study to appraise the diagnostic criteria established in 1977 on the basis of those results. A substantial number of residents in the exposed area exhibited neurologic signs, especially paresthesia of only the extremities, namely, the male residents of Minamata City showed a positive predictive value of 0.73 and a negative predictive value of 0.23. The relative risks of paresthesia only were 2.6 (2.0-3.3) and 1.2 (0.9-1.5), in Minamata and Goshonoura related to Ariake (control), respectively. At least until 1977, the diagnostic criteria remained valid, although it was inadequate. Nevertheless, presently, a follow-up study of the certified patients may lead to the development of efficient new diagnostic criteria.

    Pulgaron, Elizabeth R; Delamater, Alan M

    2014-08-01

    The incidence of overweight and obesity among children has increased dramatically in recent decades, with about one-third of children in the U.S. currently being either overweight or obese. Being overweight in early childhood increases risk for later obesity. There is evidence for the efficacy of family-based behavioral treatment to control weight and improve health outcomes. Obesity-related health risks have been documented, including metabolic syndrome. There is also increasing incidence of type 2 diabetes (T2D) among youth in recent years, with obesity and family history of T2D generally present. Lower income and ethnic minority status are associated with both obesity and T2D in youth. Most youth with T2D do not achieve optimal glycemic control, and are at high risk for later health complications. Obesity and T2D represent significant public health issues with potentially great personal and societal cost. Research addressing the prevention of obesity and T2D among youth is urgently needed.

    Reené Naidoo

    Full Text Available BACKGROUND: Staphylococcus aureus is an important pathogen in paediatric patients with bloodstream infections. The epidemiology of S. aureus bacteraemia, however, has not been well documented in children in South Africa. METHODS: A retrospective study was conducted at a children's hospital in Cape Town, South Africa, to investigate the epidemiology of S. aureus bacteraemia from 2007-2011. The incidence, clinical presentation, risk factors, management and outcomes of methicillin sensitive S. aureus (MSSA and methicillin resistant S. aureus (MRSA bacteraemia were compared. RESULTS: Over the five year study period, 365 episodes of S. aureus bacteraemia were identified. The annual incidence was 3.28 cases per 1000 hospital admissions. MRSA was responsible for 26% of S. aureus bacteraemia and 72% of nosocomial infections. Only six possible cases of community-acquired MRSA infections were described. MSSA bacteraemia was more likely to present as pulmonary and bone or joint infections, while bacteraemia without a source was the most common presentation with MRSA.  Infants, children with malnutrition, and residents of long-term care facilities were at highest risk for MRSA bacteraemia. The overall case fatality rate for S. aureus bacteraemia was 8.8% over five years, with MRSA being the only significant risk factor for mortality. CONCLUSION: The incidence of S. aureus bacteraemia and MRSA bacteraemia in children has remained stable over the past five years. MRSA is a predominantly nosocomial pathogen in children with S. aureus bacteraemia in Cape Town, South Africa.

    Objective:To investigate of epidemiological analysis of acute diarrhea in children, and to discuss the inspection of pathogenic bacterium, viruses and other microorganisms, in order to provide theoretical basis for the prevention and treatment of the disease.Methods: Five hundred and sixty-two cases of children with acute diarrhea treated in our center were selected as the research subjects, whose epidemiological data were analyzed. The fecal samples were collected for bacterial culture and identification, and the distribution characteristics of pathogenic bacteria were collected, then their relative characteristics were analyzed.Results:Children with acute diarrhea were more common in men aged 1-2 years old,and the incidence of time was more concentrated in June-August. There were four hundred and eighty-nine strains in the five hundred and sixty-two cases of children, among which the rate of viruses was the most, and the human rotavirus accounted for 30.67%, and the Shigella bacterium accounted for 20.65% in the total microorganisms, which was the highest detection rate of pathogenic bacterium. Rotavirus infection occured mainly in Winter, but the bacterial and goblet viral diarrhea was prevalent in summer.Conclusions:Children with acute diarrhea were more common in men aged 1-2 years old , and the rate of viruses in the detection of microorganisms is the highest, so targeted treatment should be taken according to the type of infection.

    Treatment alternatives have seldom been evaluated in children with cutaneous leishmaniasis (CL). We examine the clinical/epidemiological profile of children with CL considering international guidelines for local treatment. Descriptive analyses were conducted using International Center for Medical Research and Training (CIDEIM) case reports of parasitologically diagnosed patients ≤ 14 years of age from 2004 to 2010. Eligibility for local treatment based on World Health Organization/Pan American Health Organization (WHO/PAHO) criteria was determined. Among 380 children, 90% presented lesions of < 3 months duration, 54% presented single lesions < 30 mm in diameter, and 45% were ≤ 5 years old. Lesions on the head and neck were more frequent among children 0–5 years, and lesions below the head/neck were more frequent among 11- to 14-year-old children (P = 0.004). Using PAHO and WHO criteria, 26% and 53% of children, respectively, were eligible for local treatment. Recommended local treatments for New World CL have potential but limited applicability in children. Individual risk–benefit assessment and effectiveness data in children may increase eligibility.

    Phthalates are a family of industrial chemicals that have been used for a variety of purposes. As the potential consequences of human exposure to phthalates have raised concerns in the general population, they have been studied in susceptible subjects such as pregnant women, infants and children. This article aims at evaluating the impact of exposure to phthalates on reproductive outcomes and children health by reviewing most recent published literature. Epidemiological studies focusing on exposure to phthalates and pregnancy outcome, genital development, semen quality, precocious puberty, thyroid function, respiratory symptoms and neurodevelopment in children for the last ten years were identified by a search of the PubMed, Medline, Ebsco, Agricola and Toxnet literature bases. The results from the presented studies suggest that there are strong and rather consistent indications that phthalates increase the risk of allergy and asthma and have an adverse impact on children's neurodevelopment reflected by quality of alertness among girls, decreased (less masculine) composite score in boys and attention deficit hyperactivity disorder. Results of few studies demonstrate negative associations between phthalate levels commonly experienced by the public and impaired sperm quality (concentration, morphology, motility). Phthalates negatively impact also on gestational age and head circumference; however, the results of the studies were not consistent. In all the reviewed studies, exposure to phthalates adversely affected the level of reproductive hormones (luteinizing hormone, free testosterone, sex hormone-binding globulin), anogenital distance and thyroid function. The urinary levels of phthalates were significantly higher in the pubertal gynecomastia group, in serum in girls with premature thelarche and in girls with precocious puberty. Epidemiological studies, in spite of their limitations, suggest that phthalates may affect reproductive outcome and children health

SV meets more frequent only in age 40-59, thus for women a disease is marked in 4 times more frequent, than for men. Today etiology of disease remains unknown, but the value of genetic, immunological factors, pathogens, neurogenic violations and features of feed is examined. Possibility of infectious etiology SV causes considerable interest of researchers, but at first this syndrome was examined as a sharp viral infection, where the most reliable exciter is consider the virus of Epshteyna-barr. Using of intravenous introduction of globulin for SV carries experimental character and grounded on a hypothesis about immunological or infectious etiology of this disease.

    2014-08-01

    Dental caries has a significant impact on the general health and development of children. Understanding caries epidemiology is an essential task for the United Arab Emirates (UAE) policymakers to evaluate preventive programmes and to improve oral health. The purpose of this review is to collect and summarise all data available in the published literature on the epidemiology of dental caries in the UAE in children aged under 13 years. This will provide dental health planners with a comprehensive data summary, which will help in the planning for and evaluation of dental caries prevention programmes. Data were collected from the various published studies in PubMed, Academic Search Complete, Google, and the reference lists in relevant articles. Four keywords were used in the search: 'dental caries,' 'epidemiology,' 'prevalence,' and 'UAE'. All studies conducted in the UAE in general or any single emirate that sheds light on the prevalence of dental caries of children under 13 years were included in this literature review. Studies on early childhood caries and factors associated with dental caries were also included. The review comprises 11 published surveys of childhood caries in UAE. The earliest study was published in 1991 and the most recent was published in 2011. The range of decayed, missing and filled primary teeth (dmft) in UAE children (age between 4 years and 6 years) was 5.1-8.4. For the 12-year-old group the decayed missing and filled permanent teeth (DMFT) ranged from 1.6 to 3.24. Baseline data on oral health and a good understanding of dental caries determinants are necessary for setting appropriate goals and planning for preventive oral health programmes. The current data available on the dmft and DMFT indicate that childhood dental caries is still a serious dental public health problem in the UAE that warrants immediate attention by the government and policy makers.

  6. WHO Child Growth Standards Are Often Incorrectly Applied to Children Born Preterm in Epidemiologic Research.

    2015-11-01

    In epidemiologic research, there is no standard approach for accounting for gestational age (GA) at birth when interpreting postnatal anthropometric data in analyses of cohorts that include children born preterm (CBP). A scoping review was conducted to describe analytical approaches to account for GA at birth when applying the WHO Growth Standards (WHO-GS) to anthropometric data in epidemiologic studies. We searched PubMed, Scopus, MEDLINE, Embase, and Web of Science for studies that applied WHO-GS, included CBP in the study population, had access to data within 1 mo of age, and were published between 2006 and 2015 in English. Of the 80 included studies that used the WHO-GS, 80% (64 of 80) included all children regardless of GA, whereas 20% (16 of 80) restricted analyses that used WHO-GS to term-born children. Among the 64 studies that included all children, 53 (83%) used chronological age and 11 (17%) used corrected age for CBP. Of the 53 studies that used chronological age, 12 (23%) excluded data that were likely contributed by CBP (e.g., very low birth weight or extremely low outlying z scores) and 19 (36%) adjusted for or stratified by GA at birth in regression analyses. In summary, researchers commonly apply WHO-GS to CBP, usually based on chronological age. Methodologic challenges of analyzing data from CBP in the application of WHO-GS were rarely explicitly addressed. Further efforts are required to establish acceptable approaches to account for heterogeneity in GA at birth in the analysis of post-term anthropometric data in epidemiologic research.

    A computer program framework was established to enable a dairy herd production consultant to perform whole-herd analysis. The diagnostic process was an extensive data analysis 1) to derive key parameters related to production, reproduction, and health and 2) to produce input to a prognostic process....... The prognostic process synthesized the obtained information into short- or long-term prognoses for the herd through a complex herd simulation model. Site specificity of parameter estimation and forecasting and explorability of assumptions and results were major characteristics of the approach. A user acceptance...... problem related to the simulation was addressed through a simultaneous process of development and validation during the introduction of the program framework into veterinary practices. The generally slow adoption of herd simulation models in extension work could be due to lack of credibility of the models...

    2015-10-01

    Polycystic ovary syndrome (PCOS) is a heterogeneous and complex disorder that has both adverse reproductive and metabolic implications for affected women. However, there is generally poor understanding of its etiology. Varying expert-based diagnostic criteria utilize some combination of oligo-ovulation, hyperandrogenism, and the presence of polycystic ovaries. Criteria that require hyperandrogenism tend to identify a more severe reproductive and metabolic phenotype. The phenotype can vary by race and ethnicity, is difficult to define in the perimenarchal and perimenopausal period, and is exacerbated by obesity. The pathophysiology involves abnormal gonadotropin secretion from a reduced hypothalamic feedback response to circulating sex steroids, altered ovarian morphology and functional changes, and disordered insulin action in a variety of target tissues. PCOS clusters in families and both female and male relatives can show stigmata of the syndrome, including metabolic abnormalities. Genome-wide association studies have identified a number of candidate regions, although their role in contributing to PCOS is still largely unknown.

    Molecular epidemiology and clinical impact of human rhinovirus (HRV) are not well documented in tropical regions. This study compared the clinical characteristics of HRV to other common viral infections and investigated the molecular epidemiology of HRV in hospitalized children with acute respiratory infections (ARIs) in Vietnam. From April 2010 to May 2011, 1082 nasopharyngeal swabs were screened for respiratory viruses by PCR. VP4/VP2 sequences of HRV were further characterized. HRV was the most commonly detected virus (30%), in which 70% were diagnosed as either pneumonia or bronchiolitis. Children with single HRV infections presented with significantly higher rate of hypoxia than those infected with respiratory syncytial virus or parainfluenza virus (PIV)-3 (12·4% vs. 3·8% and 0%, respectively, P < 0·05), higher rate of chest retraction than PIV-1 (57·3% vs. 34·5%, P = 0·028), higher rate of wheezing than influenza A (63·2% vs. 42·3%, P = 0·038). HRV-C did not differ to HRV-A clinically. The genetic diversity and changes of types over time were observed and may explain the year-round circulation of HRV. One novel HRV-A type was discovered which circulated locally for several years. In conclusion, HRV showed high genetic diversity and was associated with significant morbidity and severe ARIs in hospitalized children.

  10. 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.

    ABSTRACT This review represents an updated scenario on the transmission cycle, epidemiology, clinical features and pathogenicity, diagnosis and treatment, and prevention and control measures of a cestode parasiteEchincoccus granulosus (E. granulosus)infection causing cystic echinococcosis (CE) in humans. Human CE is a serious life-threatening neglected zoonotic disease that occurs in both developing and developed countries, and is recognized as a major public health problem. The life cycle of E. granulosus involves a definitive host (dogs and other canids) for the adult E. granulosus that resides in the intestine, and an intermediate host (sheep and other herbivores) for the tissue-invading metacestode (larval) stage. Humans are only incidentally infected; since the completion of the life cycle ofE. granulosus depends on carnivores feeding on herbivores bearing hydatid cysts with viable protoscoleces, humans represent usually the dead end for the parasite. On ingestion ofE. granulosus eggs, hydatid cysts are formed mostly in liver and lungs, and occasionally in other organs of human body, which are considered as uncommon sites of localization of hydatid cysts. The diagnosis of extrahepatic echinococcal disease is more accurate today because of the availability of new imaging techniques, and the current treatments include surgery and percutaneous drainage, and chemotherapy (albendazole and mebendazole). But, the wild animals that involve in sylvatic cycle may overlap and interact with the domestic sheep-dog cycle, and thus complicating the control efforts. The updated facts and phenomena regarding human and animal CE presented herein are due to the web search of SCI and non-SCI journals.

    Full Text Available Abstract Background Malaria takes a heavy toll in Niger, one of the world's poorest countries. Previous evaluations conducted in the context of the strategy for the Integrated Management of Childhood Illness, showed that 84% of severe malaria cases and 64 % of ordinary cases are not correctly managed. The aim of this survey was to describe epidemiological, clinical and biological features of malaria among Methods The study was performed in 2003 during the rainy season from July 25th to October 25th. Microscopic diagnosis of malaria, complete blood cell counts and measurement of glycaemia were performed in compliance with the routine procedure of the laboratory. Epidemiological data was collected through interviews with mothers. Results 256 children aged 3–60 months were included in the study. Anthropometrics and epidemiological data were typical of a very underprivileged population: 58% of the children were suffering from malnutrition and all were from poor families. Diagnosis of malaria was confirmed by microscopy in 52% of the cases. Clinical symptoms upon admission were non-specific, but there was a significant combination between a positive thick blood smear and neurological symptoms, and between a positive thick blood smear and splenomegaly. Thrombopaenia was also statistically more frequent among confirmed cases of malaria. The prevalence of severe malaria was 86%, including cases of severe anaemia among Conclusions The study confirmed that malaria was a major burden for the National Hospital of Niamey. Children hospitalized for malaria had an underprivileged background. Two distinctive features were the prevalence of severe malaria and a high mortality rate. Medical and non-medical underlying factors which may explain such a situation are discussed.

    2011-02-01

    An extensive list of published and unpublished instruments used to investigate or evaluate sleep issues in children was collected and assessed based on the fundamental operational principles of instrument development (11 steps). Of all the available tools identified, only a few were validated and standardized using appropriate psychometric criteria. In fact, only 2 fulfill all desirable criteria and approximately 11 instruments seem to adhere to most of the psychometric tool development requirements, and were therefore assessed in greater detail. Notwithstanding, in the rapidly developing scientific world of pediatric sleep, there are too many tools being used that have not undergone careful and methodical psychometric evaluation, and as such may be fraught with biased or invalid findings. It is hoped that this initial effort in categorizing and assessing available tools for pediatric sleep will serve as recognition of the relatively early developmental stage of our field, and provide the necessary impetus for future tool development using multicentered approaches and adequate methodologies.

    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.

    Despite the great successes achieved in the fields of virology and diagnostics, several difficulties affect improvements in hepatitis C virus (HCV) infection control and eradication in the new era. New HCV infections still occur, especially in some of the poorest regions of the world, where HCV is endemic and long-term sequelae have a growing economic and health burden. An HCV vaccine is still no available, despite years of researches and discoveries about the natural history of infection and host-virus interactions: several HCV vaccine candidates have been developed in the last years, targeting different HCV antigens or using alternative delivery systems, but viral variability and adaption ability constitute major challenges for vaccine development. Many new antiviral drugs for HCV therapy are in preclinical or early clinical development, but different limitations affect treatment validity. Treatment predictors are important tools, as they provide some guidance for the management of therapy in patients with chronic HCV infection: in particular, the role of host genomics in HCV infection outcomes in the new era of direct-acting antivirals may evolve for new therapeutic targets, representing a chance for modulated and personalized treatment management, when also very potent therapies will be available. In the present review we discuss the most recent data about HCV epidemiology, the new perspectives for the prevention of HCV infection and the most recent evidence regarding HCV diagnosis, therapy and predictors of response to it.

    Non-tuberculous mycobacteria (NTM) are widely distributed in the environment, particularly in wet soil, marshland, rivers or streams, but also are causative agents of a wide variety of infections in animals and humans. Little information is available regarding the NTM prevalence in wildlife and their effects or significance in the bovine tuberculosis (bTB) epidemiology and diagnosis. This research shows the most frequently NTM isolated in lymph nodes of wild boar (Sus scrofa) from southern Spain, relating the NTM presence with the individual characteristics, the management of animals and the possible misdiagnosis of Mycobacterium bovis in concurrent infections. A total of 219 NTM isolates were obtained from 1249 wild boar mandibular lymph nodes sampled between 2007 and 2011. All but 75 isolates were identified by the PCR-restriction analysis-hsp65, and a partial sequencing of the 16S rDNA was carried out to identify the rest of the isolates. Results showed that Mycobacterium chelonae was the most frequently isolated NTM specie (133 isolates, 60.7%), followed by Mycobacterium avium (24 isolates, 11%). No relation was found regarding sex, body condition and management, but M. chelonae was more frequently detected in adults, whereas M. avium was more prevalent in subadults. The high NTM prevalence observed in the studied wild boar populations could make difficult the bTB diagnostic.

    Full Text Available Scorpion stings are a public health problem in Morocco, especially among children, who experience the most severe cases. Epidemiological and clinical findings on scorpion stings in Fez, Morocco, were evaluated in this investigation. Of 163 cases that required medical attention, 62.6% were male children. The mean age of patients was 4.8 ± 3.4 years. The mean time between stings and first medical attention was 3.36 ± 2.5 hours. Almost all cases occurred in the summer (94% and extremities represented the most frequent sting sites (86.5%. Local pain, hyperemia, scarification, vomiting, sweating, restlessness, tachycardia and tachypnea were the observed clinical symptoms. Regarding severity, 55.2% of patients belonged to class III, followed by class II (26.4% and class I (18.4%. None of our patients received antivenom; however, all of them were treated symptomatically depending on clinical manifestations.

  20. The Epidemiology of Chronic Suppurative Lung Disease and Bronchiectasis in Children and Adolescents

    2017-01-01

    In the modern era, the global burden of childhood chronic suppurative lung disease (CSLD) remains poorly captured by the literature. What is clear, however, is that CSLD is essentially a disease of poverty. Disadvantaged children from indigenous and low- and middle-income populations had a substantially higher burden of CSLD, generally infectious in etiology and of a more severe nature, than children in high-income countries. A universal issue was the delay in diagnosis and the inconsistent reporting of clinical features. Importantly, infection-related CSLD is largely preventable. A considerable research and clinical effort is needed to identify modifiable risk factors and socioeconomic determinants of CSLD and provide robust evidence to guide optimal prevention and management strategies. The purpose of this review was to update the international literature on the epidemiology, etiology, and clinical features of pediatric CSLD. PMID:28265556

    Full Text Available OBJECTIVE: To document the incidence and the descriptive epidemiology of bacterial meningitis among individuals under age 20 in a geographically defined region in Brazil during the two-year period immediately preceding the introduction of Haemophilus influenzae type b (Hib vaccines into the national immunization program of Brazil. METHODS: Population-based epidemiological study of all cases of bacterial meningitis reported among residents of Campinas, Brazil, under age 20 (n=316,570 during the period of 1997-98, using comprehensive surveillance records compiled by the Campinas Health Department from cases reported among hospital inpatients, outpatients, emergency room visits, death certificates, and autopsy reports. RESULTS: The incidence of bacterial meningitis (n=274 was 334.9, 115 and 43.5 cases/10(5 person-years (pys for residents of Campinas under age 1, 5 and 20, respectively. All cases were hospitalized, with an average length of stay of 12 days. Documented prior antibiotic use was 4.0%. The case-fatality rate of bacterial meningitis in individuals under age 20 was 9% (24/274 with 75% of deaths occurring in children under the age of five. The incidence of Hib meningitis (n=26 was 62.8 and 17 cases/10(5 pys in children age <1 and <5, respectively. CONCLUSIONS: The incidence of Hib meningitis in children under the age of 5 in Campinas during 1997-98 was similar to that reported in the US, Western Europe, and Israel prior to widespread Hib vaccine use in those regions. This study provides a baseline for later studies to evaluate changes in the etiology and incidence of bacterial meningitis in children after introduction of routine Hib vaccination in Brazil.

    Full Text Available The fatalities from Road Traffic Accidents (RTA constitute a major cause of unnatural deaths among children in Chandigarh zone of North West India. The epidemiology of RTA related deaths in this age group is lacking in our country. This retrospective study (1974–2013 included children (⩽18 years who became victims of RTA and subsequently died during the course of treatment. The postmortem and hospital records of the victims were used to collect the epidemiological data regarding age, sex, area of residence, etc. These deaths constituted 9.4% of total road accident deaths reported at this hospital. Out of a total of 709 RTA deaths in children, about 16% were reported in the block year of 1974–78 and this proportion decreased to 9.4% during the block year of 1984–88 and has remained almost constant since then. The maximum number of victims belonged to the states of Haryana (36% and Punjab (34%. A higher number of deaths were observed in rural population (60%. Most of the fatalities occurred between 12–4 pm (29.9% and pedestrians (47.8% were found to be the most commonly affected. The most common affected was the 16–18 year age group (35.3%. Injury to head and neck region (81.4% was responsible for a majority of deaths. The study concluded that the RTA remains an important cause of unnatural deaths in children. The static proportion of these deaths over the past three decades signifies that the road safety policies have been ineffective in preventing causalities and need further improvements.

    Parental separation is linked to multiple negative outcomes for children in all spheres of life. A field study was designed to estimate the epidemiology and to quantify the outcomes on the wellbeing of children from separated parents. Thus, data on socio-economic status, psychological adjustment, behavioral disorders, social relations, self-concept, and academic achievement were gathered from 346 children and adolescents, 173 separated parents, and 173 parents from intact families in the paediatric catchment area of Galicia (Spain). The results showed that parental separation had a significant negative impact on the children’s and adolescents’ family income (increasing the probability of falling below the poverty line); psychological adjustment (i.e., higher scores in anxiety, depression, hostility, paranoid ideation, and interpersonal alienation); social relations (i.e., less self-control in social relations; higher social withdrawal); self-concept (lower levels of academic, emotional, physical, and family self-concept), and academic achievement (lower academic achievement with higher school dropout rates). Moreover, children from separated families had a higher probability of being exposed to gender violence. Epidemiologically, parental separation is associated to the probability of falling below the poverty line 33.9%; being exposed to gender violence 43.2%; and symptoms such as depression, anxiety, hostility, paranoid ideation interpersonal alienation, and social withdrawal, i.e., 20, 17, 27, 20, 19, and 35.5%, respectively. Inversely, self-control in social relations, and academic, emotional, physical, and family self-concept fell to 16, 32, 27, 22, and 37%, respectively. The interrelationship among these variables and the implications of these results for interventions are discussed. PMID:27826265

    Background Syncope is a common clinical problem with multiple causes. Vasovagal syncope (WS) is by far the most frequent cause of syncope in children and adolescents. The traditional diagnostic approach to VVS of children and adolescents is based on a series of tests to exclude all other causes, which is complex and time and medical resource consuming. Attempts have been made to develop a new cost-effective diagnostic approach to avoid these problems. This study aimed to compare the economic effectiveness and diagnostic value of the traditional diagnostic approach to VVS of children with a new diagnostic approach.Methods One hundred and eighteen children diagnosed as VVS were divided into two groups according to the different diagnostic approaches. The diagnostic value of the two diagnostic approaches was then analyzed. Meanwhile, the costs of hospitalization, diagnostic testing and hospital stay were determined. Data were evaluated by the cost-minimization analysis.Results The diagnostic value of the new diagnostic approach was similar to that of the traditional diagnostic approach (56.57% vs. 53.91%, P=0.697). However, the cost of hospitalization per patient by the new diagnostic approach was (1507.08±144.63) Yuan (RMB) which was less than that of the traditional diagnostic approach (2603.64±P08.19) Yuan.The costs of diagnostic tests per patient by the new diagnostic approach was (1256.04±109.14) Yuan and by the traditional approach (2175.22±153.32) Yuan.Conclusion Compared to the traditional diagnostic approach to diagnose VVS in children and adolescents, the new diagnostic approach is of a good economic value, and it should be popularized in clinical practice.

    Infectious Diarrhea caused by rotavirus and adenovirus, is a leading cause of death in children in sub-Sahara Africa but there is limited published data on the diverse rotavirus genotypes and adenovirus serotypes circulating in the Republic of Congo. In this study, we investigated the prevalence of severe diarrhea caused by rotavirus A (RVA) and Adenovirus serotype 40 and 41 in Congolese children hospitalized with severe gastroenteritis. Stool samples were collected from 655 Congolese children less than 60 months of age hospitalized with acute gastroenteritis between June 2012 and June 2013. Rotavirus and adenovirus antigens were tested using commercially available ELISA kits and the RVA G- and P- genotypes were identified by seminested multiplex RT-PCR. Three hundred and four (46.4%) children were tested positive for RVA. Adenovirus infection was found in 5.5% of the 564 tested children. Rotavirus infection was frequently observed in children between 6-12 months (55.9%). The dry season months recorded increased RVA infection while no seasonality of adenovirus infection was demonstrated. The most common RVA genotypes were G1 (57.5%), G2 (6.4%), G1G2 mixture (15.5%), P[8] (58%), P[6] (13.2%), and P[8]P[6] mixture (26%). Additionally, the genotype G12P[6] was significantly associated with increased vomiting. This first study on Congolese children demonstrates a high prevalence and clinical significance of existing rotavirus genotypes. Adenovirus prevalence is similar to that of other Central African countries. This baseline epidemiology and molecular characterization study will contribute significantly to the RVA surveillance after vaccine implementation in the country.

    Full Text Available Context: Road traffic injuries (RTIs are the leading cause of death and globally kill 1.2 million people every year and leave 20 - 50 million people injured and disabled. In Iran, traffic related fatalities are the leading cause of death among all inadvertent fatal injuries imposed on children under five. Herein, authors review the epidemiological studies performed on vehicle accidents among Iranian children and adolescents to improve the knowledge about these preventable events. Evidence Acquisition: International databases including PubMed, Google scholar, science direct Cochrane library, and national data bases such as scientific information database (SID were searched for terms; children, motor vehicle accident, road traffic injuries, Iran 2000 - 2015. Publication in Persian or English language related to the subject including Iranian children and adolescent's age groups were included. Among the 312 articles, 11 (two abstracts and nine full texts were selected. Nine full texts were reviewed. Results: From 22865 victims, about 3578 children and adolescents under 19 years old were identified. Males were more affected than females. Pedestrian injury with 43.66% was the most common case of road traffic injuries. Head trauma was the most common cause of injuries reported by eight of the reviewed articles. Most of the accidents occurred between 1:00 - 6:00 PM. Most of RTIs occurred in summer. Care by emergency medical services (EMS (29.14% was reported by five out of the nine reviewed article. Conclusions: Most of the road traffic injuries among Iranian children and adolescents are preventable using appropriate preventive strategies such as safety facilities, safe vehicles, and safe traffic behavior, and establishing comprehensive public education programs for older children and their parents.

    Alveolar echinococcosis (AE), caused by the larval (metacestode) stage of Echinococcus multilocularis, is considered one of the most serious parasitic zoonoses in Central and Eastern Europe and is emerging also in large parts of Asia and in North America. The red fox represents the main definitive host of E. multilocularis in Europe, but the raccoon dog, the domestic dog and to a much lesser extent the domestic cat also represent potential definitive hosts. The natural intermediate hosts of E. multilocularis are mainly voles. The spectrum of accidental hosts is broad and includes many species of monkeys, pigs, dogs and humans which get infected by oral uptake of the viable eggs. Yet, human AE is a very rare disease in Europe; incidences have increased in recent years, while the infection is widely distributed in foxes with high prevalences reaching up to 70% in some areas. Generally, infected foxes represent a zoonotic risk, which may be particularly relevant in urban areas. Furthermore, there is concern that the risk for humans to acquire AE may rise due to the suspected geographical spread of the parasite as assessed by infections in its definitive hosts and the high prevalences in some regions. Monitoring and surveillance activities have therefore been initiated in a few European countries. Several diagnostic strategies have been developed and validated in recent years, applying classical worm detection by microscopy, but also immunological (ELISA for coproantigen detection) and molecular tests (copro-DNA detection by PCR). However, there is an urgent need for defining minimal requirements and harmonised approaches for these activities to allow for a reliable assessment of the epidemiological situation in Europe and comparable results from different countries.

    Three girls of Moroccan descent, aged 9, 10 and 7 years, presented with fever, joint pain and other symptoms. After Streptococcus infection and carditis were confirmed and the Jones criteria for acute rheumatic fever were met, the patients were treated with penicillin and acetylsalicylic acid. All 3 patients recovered. However, the second girl presented 2 months later with cardiac decompensation caused by valve disorders, after which aortic and mitral valvuloplasty was performed. The third girl developed joint pain again after 3 weeks and was diagnosed with juvenile idiopathic arthritis; treatment was adjusted accordingly. The prevalence of rheumatic heart diseases is 10-20 times higher in developing countries than in industrialised nations. The diagnosis 'acute rheumatic fever' should be considered in children of school age with unexplained fever, also when the Jones criteria have not yet been met. This may apply to migrant children in particular.

    Full Text Available ABSTRACT: BACKGROUND: Cryptosporidium has emerged as one of the major paras itic agents as a cause of diarrhoea in children. Various epidemi ological factors have been described by different workers. Aims: This study was done to det ermine different epidemiological factors incriminated in cryptosporidiosis. Methods: Stool sam ples from 240 children with diarrhoea were examined for presence of Cryptosporidium. Wet mo unt examination, modified Ziehl- Neelsen (Z.N. and Safranine-methylene blue stainin g methods were performed. For 177 samples, ELISA was also done. Detailed history of pat ients regarding their socioeconomic status and various sociodemographic factors was taken. Stat istical Analysis: Chi-square and z tests were used to compare differences between the groups. A p value of ≤0.05 was considered significant. Results: Majority of patients were in C lass IV socioeconomic group. Top-feeding, use of insanitary wells for drinking purposes, close ass ociation with animals, field defaecation and residence in rural areas were different factors tha t contributed to the spread of infection. Oocysts were present in 21 children on different sta ining procedures and 23 were positive by ELISA. Conclusion: Different sociodemographic factor s like improper sanitation practices, drinking contaminated water, early withdrawal of br east feeding and close intimacy with animals are various factors that can enhance the spr ead of infection in community. Preventive measures are of great importance in control of sprea d of infection as there is no specific therapy for cryptosporidiosis.

    The objective of this study is to describe the epidemiology of playground equipment-related injuries. This is a retrospective analysis of data for children 18 years old and younger from the National Electronic Injury Surveillance System of the United States Consumer Product Safety Commission for 1996 through 2005. There were an estimated 2,136,800 playground equipment-related injuries to children 18 years and younger treated in hospital emergency departments in the United States during the 10-year period. The leading mechanism of injury was falls (75.1%), followed by impact/striking (10.5%), cutting/ pinching/crushing (7.7%), entrapment/ entanglement (1.4%), trip/slip (1.1%), and other/ unknown (4.1%). The leading type of injury sustained by patients was a fracture (35.4%), followed by contusion/ abrasion (19.6%) and laceration (19.6%). The consistency of the large annual number of playground equipment-related injuries to children is evidence that more needs to be done to prevent these injuries. More research should be conducted to develop and implement arm fracture-specific criteria for surface performance.

    Full Text Available Introduction and Aim. Type-1-diabetes mellitus (T1DM is the most commonly diagnosed type of DM in children and adolescents. We aim to identify the epidemiological profile, risk factors, clinical features, and factors related to delayed diagnosis or mismanagement in children with newly diagnosed T1DM in Taif, Saudi Arabia. Patients and Methods. Ninety-nine newly diagnosed patients were included in the study along with 110 healthy controls. Patients were classified into 3 groups (I: >2 years, II: 2–>6 years, and III: 6–12 years. Both patients and controls were tested for C-peptide, TSH, and autoantibodies associated with DM and those attacking the thyroid gland. Results. Diabetic ketoacidosis was present in 79.8%. Delayed and missed diagnoses were recorded in 45.5%, with significant correlation to age and district of origin. Severity at presentation showed significant correlation with age and cow’s milk feeding. Group I, those with misdiagnosis or positive DM related autoantibodies, had more severe presentations. The correlation of C-peptide and TSH levels in patients and controls was significant for C-peptide and nonsignificant for TSH. Conclusion. Misdiagnosis and mismanagement are common and account for more severe presentation, especially in young children >2 years. Early introduction of cow’s milk appears to be a risk factor for the development of T1DM.

    Full Text Available Monitoring traumatic dental injury (TDI in primary teeth through epidemiological cross-sectional surveys provides descriptive information relevant to the development of public policies focused on the prevention of such injuries for the target population. The aim of this study was to assess the prevalence of TDI in 5- to 6-year-old Brazilian children and its association with biological and socioeconomic factors. A total of 684 children aged 5 to 6 years old, from 11 public schools in the city of Barueri (Brazil were evaluated. Clinical examinations were carried out in the schools, by two trained and calibrated examiners. Gauze and a mouth mirror were used for the examinations. The reported TDIs were classified according to the Andreasen (2007 criteria for primary teeth. The results showed that 52.3% of the children had TDI. Enamel fracture (63.4% was the most frequently observed sign of TDI, and the most affected teeth were the primary maxillary central incisors (26.9% maxillary right central incisor and 24% maxillary left central incisor. There was no association between the presence of TDI and biological or socioeconomic factors. In conclusion, the prevalence of TDI was high and had no statistically significant association with biological and socioeconomic factors.

    A retrospective study covering ten years (1987-1996) was conducted to assess the epidemiology, clinical features and management of cancrum oris (noma) in children from Burkina Faso. Fifty nine (59) children were admitted with cancrum oris at the paediatrics and maxillo-facial surgery units of Bobo-Dioulasso, the second town of Burkina Faso. The hospital prevalence of noma is 1.5/1000. 81% of the cases were in the 1 to 5 years age group and 58% were females. Predisposing factors include poverty, lack of immunization, malnutrition, bad oral hygiene, measles and parasitic diseases. The cheek was involved in 31% of the cases. Cure was obtained in 80% of patients after medical and surgical treatment. However, many sequels were observed. Post operative outcome is complicated by the children's growth and often results in retractions, recurrence of ulcers or constriction. Psychological and social problems are associated. Management is difficult in our setting because of the lack of information, cost of the treatment and the absence of well-equipped plastic surgery units.

    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 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.

    Autoimmune hepatitis (AIH) is a progressive inflammatory liver disorder that is rare in children and adolescents.AIH has a broad clinical spectrum and a quick response to treatment with corticosteroids and immunosuppressive medication.The available diagnosis criteria have limitations and should be evaluated in pediatric populations.Recently,some studies reported that the 2008 simplified diagnostic criteria for AIH could be used in children with high sensibility and specificity.In addition,the authors reported that globulin and immunoglobulin G levels can be used interchangeably for diagnostic purposes.They also demonstrated that the 2008 simplified criteria fail in identifying patients with fulminant hepatic failure.Here,we discuss the limitations of the use of these criteria in pediatric patients and the requirement of more studies to improve the diagnosis of AIH in children.

    We report on our experience with routine abdominal ultrasonography in 120 children (aged 3-15 years) with recurrent abdominal pain, in order to determine the diagnostic value of this investigation. Eight children (7%) revealed sonographic abnormalities: gallbladder stone (n = 2), splenomegaly (n...... = 1) and urogenital abnormalities (n = 5). The recurrent abdominal pain could be explained by these findings in only two (may be three) cases. CONCLUSION: The diagnostic value of abdominal ultrasonography in unselected children with recurrent abdominal pain is low. However, the direct visualization...... of the abdominal structures as being normal may be helpful to the parents and the child in their understanding and acceptance of the benign nature of recurrent abdominal pain....

    Diagnostic laboratories frequently select a subjective cutoff value for real-time amplification assays, above which a threshold cycle (Ct) value is deemed false. Commonly, higher Ct values are interpreted as amplification or fluorescence artifacts, or cross contaminations. Although the implementation of Ct cutoff might be reasonable, its justification and selection should be based on evidence. The current article reviewed evidence-based strategies to select Ct cutoffs grouped in analytical and epidemiologic approaches. Analytical strategies use criteria gathered during the assay development and include fluorescence threshold, reaction end-cycle, limit of detection, and artifact investigation. Variability in amplification efficacy across test runs may induce some instability in an intended Ct cutoff and requires some standardization or normalization procedures. Epidemiologic strategies use criteria based on either the probability or the cost of a false test result associated with a specified cutoff. Cutoffs, depending on the intended purpose of the test, can be selected graphically to minimize the probability of either false-positive or false-negative results by using two-graph receiver operating characteristics curves. The assay's diagnostic sensitivity and specificity may vary with the tested population, thus, the estimated two-graph receiver operating characteristics curve is population dependent and should be established for the targeted population. Although the selection of a cutoff based on misclassification cost depends on infection prevalence, the selection based on predictive values does not. To optimize the test average diagnostic performance, the Ct cutoff should be selected when diagnostic odds ratio is maximal. Epidemiologic approaches were illustrated by selecting Ct cutoffs for a real-time assay for Infectious salmon anemia virus.

    The interrelationship between the Autism Diagnostic Interview-Revised (ADI-R), Autism Diagnostic Observation Schedule-Generic (ADOS-G) and clinical classification was studied in 184 children and adolescents with Mental Retardation (MR). The agreement between the ADI-R and ADOS-G was fair, with a substantial difference between younger and older children (5-8 vs. 8+ years). Compared with the Diagnostic and Statistical Manual of Mental Disorders-IV-TR (DSM-IV-TR) classification of Autistic Disorder (AD) and Pervasive Developmental Disorder (PDD), both instruments measure AD or PDD validly and reliably. Even in low-functioning children the interrelationship between the instruments and the clinical classification was satisfactory. The combination of ADI-R and ADOS-G identifies AD or PDD, as described in the DSM-IV-TR, most appropriately. Both instruments seem to be of great value in the diagnostic process of PDD in children and adolescents with MR.

    The pediatric diagnostic odyssey is a period of uncertainty and emotional turmoil for families, often characterized by multiple minor medical procedures (such as venipuncture) that children may find distressing. Interventions to reduce distress are rarely offered, despite evidence that this is crucial both for avoiding anticipatory anxiety before future procedures and for improving healthcare compliance in adulthood. We interviewed ten mothers of children with neuromuscular disorders, asking about their perceptions of their child's experiences with different medical procedures, the emotional impact of the diagnostic odyssey, implications of obtaining a diagnosis, and interactions with healthcare providers. We coded interviews in ATLAS.ti (version 7.0) based on a priori and emergent themes, and analyzed them based on the principles of interpretive description. We found that predicting and assessing children's reactions to procedures is challenging; parents reported non-invasive procedures such as x-rays were distressing for some children, and that providers did not detect subtle indicators of distress. Parents valued obtaining a diagnosis because it validated their concerns, enabled planning for the child's future healthcare needs, and allowed access to established support networks. This study suggests that healthcare providers can improve the experience of the diagnostic odyssey by validating family concerns and connecting them to support services that are available without a diagnosis.

    Full Text Available Clinical and epidemiological research on the evolution of measles in children in Leningrad – St. Petersburg from 1927–2014 with an analysis of the effectiveness of treatment of this infection. Divided into three periods of fighting «child plague». First period – to use in the practice of specific therapies and antibacterial drugs, characterized by high morbidity, severe weight, high rates of mortality. In the second period the use of donor serum syvotrotki convalescents and sulfa drugs significantly lowered the mortality rate due to the effective treatment of pneumococcal pneumonia. The use of penicillin and broad-spectrum antibiotics led to a further reduction in the severity of measles, a sharp decline in mortality – to tenths and hundredths of a percent. The third period is due to the mass of active immunization against measles, characterized by a significant decline in incidence rates up to her absence in some years. Combined therapy of children with measles in modern conditions with the inclusion etiotropic drugs (Viferon causes rapid regression of the symptoms of measles, warns layering respiratory viral infection contributes to the smooth course of the disease.

    Full Text Available Abstract Background Recent studies strongly suggest that some respiratory viruses are associated with the induction of acute wheezing and/or exacerbation of bronchial asthma. However, molecular epidemiology of these viruses is not exactly known. Methods Using PCR technology, we attempted to detect various respiratory viruses from 115 Japanese children. Furthermore, the detected viruses were subjected to homology, pairwise distance, and phylogenetic analysis. Results Viruses were detected from 99 (86.1% patients. Respiratory syncytial virus (RSV alone and human rhinovirus (HRV alone were detected in 47 (40.9% and 36 (31.3% patients, respectively. Both RSV and HRV were detected in 14 (12.2% patients. Human metapneumovirus (HMPV alone and human parainfluenza virus (HPIV alone were detected in 1 (0.9% patient each, respectively. Homology and phylogenetic analyses showed that the RSV and HRV strains were classified into genetically diverse species or subgroups. In addition, RSV was the dominant virus detected in patients with no history of wheezing, whereas HRV was dominant in patients with a history of wheezing. Conclusions The results suggested that these genetically diverse respiratory viruses, especially RSV and HRV, might be associated with wheezing in Japanese children.

    The introduction of pneumococcal conjugate vaccine may change the epidemiology of Streptococcus pneumoniae. The increased prevalence of non-vaccine serotypes as the cause of pneumococcal diseases has already reported in the United States and Europe. However, little attention has been focused on the S. pneumoniae. In this study, nonencapsulated S. pneumoniae were identified in 15 isolates (6.4%) out of 236 pneumococcal strains obtained from the nasopharynges of children with acute otitis media (AOM), in 3 isolates (14.3%) out of 21 strains from acute rhinosinusitis, and in 2 isolates (12.5%) out of 16 nasopharyngeal carriage strains obtained from normal healthy children. Among the 20 nonencapsulated S. pneumoniae isolates, 15 (75.0%) isolates had the pspK gene. Seven sequence types (STs) were identified: ST7502 (5 strains), ST1106 (2 strains), ST7803 (2 strains), ST7786 (1 strain), ST6741 (1 strain), ST7496 (1 strain), and ST8642 (1 strain). Because nonencapsulated S. pneumoniae strains are not targeted by the current available pneumococcal vaccines, these strains will gradually become more common in nasopharyngeal carriage. The increase in colonization and dissemination of these strains would increase the risk of AOM and other systemic pneumococcal diseases against which current vaccines cannot provide protection. Nonencapsulated S. pneumoniae may thus become more prevalent as human pathogen.

    Full Text Available Background: Urinary tract infections (UTIs are among the most common infections in the pediatric population. Over the last two decades, antibiotic resistance is increasing significantly as extended spectrum beta lactamase (ESBL producing organisms are emerging. The aim of this study is to provide a comprehensive view of the epidemiologic characteristics of UTIs in hospitalized children, examine the risk factors of UTIs caused by ESBL-producing organisms, and determine the resistance patterns in the isolated organisms over the last 10 years. Methods: Retrospective chart review was conducted at two Lebanese medical centers. Subjects were identified by looking at the following ICD-9 discharge codes: Urinary tract infection, UTI, Cystitis, and/or Pyelonephritis. Children less than 18 years of age admitted for UTI between January 1st, 2001 and December 31st, 2011 were included. Cases whose urine culture result did not meet our definition for UTI were excluded. Chi-square, Fisher’s exact test, and multivariate logistic regression were used to determine risk factors for ESBL. Linear regression analysis was used to determine resistance patterns.Results: The study included 675 cases with a median age of 16 months and female predominance of 77.7% (525 cases. Of the 584 cases caused by Escherichia coli or Klebsiella spp, 91 cases (15.5% were found to be ESBL-producing organisms. Vesico-ureteral reflux and previous antibiotics use were found to be independent risk factors for ESBL-producing E. coli and Klebsiella spp (p-value < 0.05. A significant linear increase in resistance to all generations of Cephalosporins (r2=0.442 and Fluoroquinolones (r2=0.698 was found.Conclusion: The recognition of risk factors for infection with ESBL-producing organisms and the observation of increasing overall resistance to antibiotics warrant further studies that might probably lead to new recommendations to guide management of UTIs and antibiotic use in children an

    This study analysed the usefulness of the Wechsler Intelligence Scale for Children-Third Edition in identifying specific cognitive impairments that are linked to developmental dyslexia (DD) and the diagnostic utility of the most common profiles in a sample of 100 Portuguese children (50 dyslexic and 50 normal readers) between the ages of 8 and 12 years. Children with DD exhibited significantly lower scores in the Verbal Comprehension Index (except the Vocabulary subtest), Freedom from Distractibility Index (FDI) and Processing Speed Index subtests, with larger effect sizes than normal readers in Information, Arithmetic and Digit Span. The Verbal-Performance IQs discrepancies, Bannatyne pattern and the presence of FDI; Arithmetic, Coding, Information and Digit Span subtests (ACID) and Symbol Search, Coding, Arithmetic and Digit Span subtests (SCAD) profiles (full or partial) in the lowest subtests revealed a low diagnostic utility. However, the receiver operating characteristic curve and the optimal cut-off score analyses of the composite ACID; FDI and SCAD profiles scores showed moderate accuracy in correctly discriminating dyslexic readers from normal ones. These results suggested that in the context of a comprehensive assessment, the Wechsler Intelligence Scale for Children-Third Edition provides some useful information about the presence of specific cognitive disabilities in DD. Practitioner Points. Children with developmental dyslexia revealed significant deficits in the Wechsler Intelligence Scale for Children-Third Edition subtests that rely on verbal abilities, processing speed and working memory.

    The incidence and prevalence of intestinal parasites in children is most likely due to lack of natural or acquired resistance and differences in behavior and habits closely related to environmental and socioeconomic determinants. The most important protozoa that parasitize humans are Giardia, Entamoeba, Blastocystis, and Cryptosporidium. These parasites present wide intraspecific genetic diversity and subsequently classified into assemblages and subtypes. The Amazon basin is the largest in the world and is the fifth freshwater reserve on the planet. Contradictorily, people living in these areas (Indigenous populations) have poor quality of life, which favors the infection of diseases of fecal-oral transmission. The aim of this work was to unravel the molecular epidemiology of Giardia, Blastocystis and Cryptosporidium across four communities (Puerto Nariño, San Juan del Soco, Villa Andrea and Nuevo Paraíso). We obtained 284 fecal samples from children under 15 years old that were analyzed by direct microscopy (261 samples) and Real Time PCR (qPCR) (284 samples). The positive samples for these protozoa were further characterized by several molecular markers to depict assemblages and subtypes. We observed a frequency of Giardia infection by microscopy of 23.7% (62 samples) and by qPCR of 64.8% (184 samples); for Blastocystis by microscopy of 35.2% (92 samples) and by qPCR of 88.7% (252 samples) and for Cryptosporidium only 1.9% (5 samples) were positive by microscopy and qPCR 1.8% (5 samples). Regarding the Giardia assemblages, using the glutamate dehydrogenase (gdh) marker we observed AI, BIII and BIV assemblages and when using triose phosphate isomerase (tpi) we observed assemblages AI, AII, BIII and BIV. In contrast, Blastocystis STs detected were 1, 2, 3, 4, and 6. Lastly, the species C. viatorum, C. hominis (with the subtypes IdA19 and IaA12R8) and C. parvum (with the subtype IIcA5G3c) were identified. We observed a high profile of zoonotic transmission

    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

    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.

    Infection is the main factor of morbidity and mortality in children with sickle cell disease (SCD). The objective of this study is to determine it's epidemiologic outline in senegalese children and adolescents with SCD. We retrospectively studied infection data in all the charts of a cohort of 323 patients with SCD (307 SS, 13 SC and 3 s beta + thalassemia) followed at Albert Royer children hospital from january 1991 to december 1997. Serum sampling was systematically made for HIV and antigen HBs serology in all patients we received in the last 3 months (october to december 1997). Patients were aged from 5 months to 22 years (medium age = 8 years). 813 infection episodes were diagnosed, concerning 184 patients (56 per cent). SS patients were more affected (59 per cent) than the others (23 per cent, p = 0.04). ENT and broncho-pulmonary onsets were more frequent but had a generally benign course. Menigitidis, septicemia and osteomyelitis were exclusively diagnosed in SS patients. Their prevalences in this group were respectively: 1.0 per cent, 4.9 per cent and 9.8 per cent. HIV serology was determined in 155 patients, including 41 per cent with blood transfusion antecedents. All tests were negative. HBs antigen was determined in 104 patients and seroprevalence was 7.7 per cent in the whole group and 6.0 per cent in patients with transfusion antecedents and 7.7 per cent for the others. Plasmodium falciparum malaria onset was observed in 9.6 per cent of our patients and there was no case of cerebral malaria. Infection was involved in 9 of the 11 cases of death. Then infection constitute the major problem in children and adolescents with SCD in Dakar. However prevalences of severe onsets are comparable to data in Europe despite our poor follow up conditions. Senegal haplotype may lead to a good tolerance of SCD. Negative HIV serology and low HBs antigen seroprevalence in transfused patients are attributed to a relatively low level of HIV prevalence in the general

    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.

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.

    Human rhinoviruses (HRV) have been re-classified into three species (A-C), but the recently discovered HRV-C strains are not fully characterized yet. This study aimed to undertake a molecular and epidemiological characterization of HRV strains infecting children hospitalized over one year in two large research hospitals in Rome. Nasal washings from single HRV infections were retrospectively subjected to phylogenetic analysis on two genomic regions: the central part of the 5'Untranslated Region (5'UTR) and the Viral Protein (VP) 4 gene with the 5' portion of the VP2 gene (VP4/2). Forty-five different strains were identified in 73 HRV-positive children: 55 % of the cases were HRV-A, 38 % HRV-C and only 7 % HRV-B. HRV-C cases were less frequent than HRV-A during summer months and more frequent in cases presenting wheezing with respect to HRV-A. Species distribution was similar with respect to patient age, and seasonality differed during summer months with fewer HRV-C than HRV-A cases. On admission, a significantly higher number of HRV-C cases presented with wheezing with respect to HRV-A. The inter- and intra-genotype variability in VP4/2 was higher than in 5'UTR; in particular, HRV-A patient VP4/2 sequences were highly divergent (8-14 %) at the nucleotide level from those of their reference strains, but VP4 amino acid sequence was highly conserved. In HRV-C isolates, the region preceding the initiator AUG, the amino acids involved in VP4 myristoylation, the VP4-VP2 cleavage site and the cis-acting replication element were highly conserved. Differently, VP4 amino acid conservation was significantly lower in HRV-C than in HRV-A strains, especially in the transiently exposed VP4 N-terminus. This study confirmed the high number of different HRV genotypes infecting hospitalized children over one year and reveals a greater than expected variability in HRV-C VP4 protein, potentially suggestive of differences in replication.

    Background The epidemiologic characteristics of children and young adults with acute kidney injury have been described in single-center and retrospective studies. We conducted a multinational, prospective study involving patients admitted to pediatric intensive care units to define the incremental risk of death and complications associated with severe acute kidney injury. Methods We used the Kidney Disease: Improving Global Outcomes criteria to define acute kidney injury. Severe acute kidney injury was defined as stage 2 or 3 acute kidney injury (plasma creatinine level ≥2 times the baseline level or urine output <0.5 ml per kilogram of body weight per hour for ≥12 hours) and was assessed for the first 7 days of intensive care. All patients 3 months to 25 years of age who were admitted to 1 of 32 participating units were screened during 3 consecutive months. The primary outcome was 28-day mortality. Results A total of 4683 patients were evaluated; acute kidney injury developed in 1261 patients (26.9%; 95% confidence interval [CI], 25.6 to 28.2), and severe acute kidney injury developed in 543 patients (11.6%; 95% CI, 10.7 to 12.5). Severe acute kidney injury conferred an increased risk of death by day 28 after adjustment for 16 covariates (adjusted odds ratio, 1.77; 95% CI, 1.17 to 2.68); death occurred in 60 of the 543 patients (11.0%) with severe acute kidney injury versus 105 of the 4140 patients (2.5%) without severe acute kidney injury (P<0.001). Severe acute kidney injury was associated with increased use of mechanical ventilation and renal-replacement therapy. A stepwise increase in 28-day mortality was associated with worsening severity of acute kidney injury (P<0.001 by log-rank test). Assessment of acute kidney injury according to the plasma creatinine level alone failed to identify acute kidney injury in 67.2% of the patients with low urine output. Conclusions Acute kidney injury is common and is associated with poor outcomes, including increased

    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.

    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.

    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.

    The goal of this study was to develop a semistructured clinical interview for assessing acute stress disorder (ASD) in youth and test its psychometric properties. Youth (N = 168) with an acute burn or injury were administered the acute stress disorder module of the Diagnostic Interview for Children and Adolescents (DICA-ASD). The DICA-ASD demonstrated strong psychometric properties, including high internal consistency (alpha = .97) and perfect diagnostic interrater agreement (kappa = 1.00). Participants diagnosed with ASD scored significantly higher than those not diagnosed on validated traumatic stress symptomatology measures but not on other symptomatology measures, providing evidence of convergent and discriminant validity. Preliminary evidence supports the reliability and validity of the first semistructured clinical interview for diagnosing ASD in youth.

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

    Orf virus leads to self-limited, subacute cutaneous infections in children who have occupational or recreational contact with infected small ruminants. Breaches in the integument and contact with animals recently vaccinated for orf may be important risk factors in transmission. Common childhood behaviors are likely important factors in the provocation of significant contact (ie, bites) or in unusual lesion location (eg, facial lesions). Clinician recognition is important in distinguishing orf infection from life-threatening cutaneous zoonoses. Recently developed molecular techniques provide diagnostic precision and newer topical therapeutics may hasten healing.

    A total of 125 isolates were recovered from adenoids and/or nasopharynx of 170 children aged 2 to 5 from south-east Poland; they had undergone adenoidectomy for recurrent and/or persistent symptoms of upper respiratory tract infections. Pneumococcal isolates were analyzed by phenotyping (serotyping and antimicrobial resistance tests) and genotyping together with the clonality of the pneumococcal isolates based on resistance determinants, transposon distribution and multilocus sequence typing (MLST). Serotypes 19F, 6B and 23F constituted 44.8% of the isolates. Among all of the strains, 44.8% showed decreased susceptibility to penicillin and resistance to co-trimoxazole (52.8%), tetracycline (38.4%), erythromycin (53.6%), clindamycin (52.8%) and chloramphenicol (27.2%) was observed. Tn6002 was found in 34.8% of erythromycin-resistant isolates while composite Tn2010-in 16.7% of erm(B)-carrying isolates that harboured also mef(E) gene. Tn3872-related elements were detected in 27.3% of erythromycin-resistant strains. In the majority of chloramphenicol-resistant catpC194-carrying isolates (79.4%), ICESp23FST81-family elements were detected. The genotyping showed that pneumococcal population was very heterogeneous; 82 sequence types (STs) were identified, and the most frequent contributed to not more than 8% of the isolates. Nearly 44% STs were novel, each of them was recovered only from one child. Four STs belonged to one of the 43 worldwide spread resistant pneumococcal clones currently accepted by Pneumococcal Molecular Epidemiology Network (PMEN), i.e. Spain 9V-3, Spain 23F-1, Norway NT-42 and Poland 6B-20, accounting for 12 (16.7%) of the 75 nonususceptible isolates, and five STs were single-locus variants of PMEN resistant clones (England 14-9, Spain 9V-3, Spain 23F-1, Greece 21-30, Denmark 14-32), accounting 9 (12%) of nonsusceptible isolates. A few MDR clones belonging to 6B and 19F serotypes found among preschool children emphasizes rather the role of clonal

    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.

    Highlights: •Postmortem MR imaging (PMMR) has high overall accuracy for abdominal pathology in foetuses, newborns and children. •PMMR is particularly good at detecting renal abnormalities, and relatively poor at detecting intestinal abnormalities. •In clinical practice, PMMR may be a useful alternative or adjunct to conventional autopsy in foetuses and children for detecting abdominal abnormalities. -- Abstract: Background: To compare the diagnostic accuracy of post-mortem magnetic resonance imaging (PMMR) specifically for abdominal pathology in foetuses and children, compared to conventional autopsy. Methods: Institutional ethics approval and parental consent was obtained. 400 unselected foetuses and children underwent PMMR using a 1.5 T Siemens Avanto MR scanner before conventional autopsy. PMMR images and autopsy findings were reported blinded to the other data respectively. Results: Abdominal abnormalities were found in 70/400 (12%) autopsies. Overall sensitivity and specificity (95% confidence interval) of PMMR for abdominal pathology was 72.5% (61.0, 81.6) and 90.8% (87.0, 93.6), with positive (PPV) and negative predictive values (NPV) of 64.1% (53.0, 73.9) and 93.6% (90.2, 95.8) respectively. PMMR was good at detecting renal abnormalities (sensitivity 80%), particularly in foetuses, and relatively poor at detecting intestinal abnormalities (sensitivity 50%). Overall accuracy was 87.4% (83.6, 90.4). Conclusions: PMMR has high overall accuracy for abdominal pathology in foetuses, newborns and children. PMMR is particularly good at detecting renal abnormalities, and relatively poor at detecting intestinal abnormalities. In clinical practice, PMMR may be a useful alternative or adjunct to conventional autopsy in foetuses and children for detecting abdominal abnormalities.

    Full Text Available We aimed to evaluate sociodemographic, epidemiological, and clinical risk factors for pulmonary tuberculosis (PTB in children presenting with severe acute malnutrition (SAM and pneumonia. Children aged 0 to 59 months with SAM and radiologic pneumonia from April 2011 to July 2012 were studied in Bangladesh. Children with confirmed PTB (by culture and/or X-pert MTB/RIF (cases = 27 and without PTB (controls = 81; randomly selected from 378 children were compared. The cases more often had the history of contact with active PTB patient (P < .01 and exposure to cigarette smoke (P = .04 compared with the controls. In logistic regression analysis, after adjusting for potential confounders, the cases were independently associated with working mother (P = .05 and positive tuberculin skin test (TST; P = .02. Thus, pneumonia in SAM children is a common presentation of PTB and further highlights the importance of the use of simple TST and/or history of contact with active TB patients in diagnosing PTB in such children, especially in resource-limited settings.

    Lack of recognition of human immunodeficiency virus (HIV) infection especially in children and delayed implementation of effective control programs makes HIV infection as a major cause for concern. Information on HIV epidemiology in Iran as well as other Islamic countries is limited. The aim of our study was to describe the clinical manifestation and laboratory finding of HIV infected children who were admitted to a referral Children Medical Center (CMC) in Tehran, Iran, during 11 years from January 2002 to January 2013. This was a retrospective study carried out over a period of 11 years. The records of all patients attending to the CMC with confirmed acquired immunodeficiency syndrome (AIDS) were screened. The patients were evaluated for social circumstance, family history, age, gender, clinical, and laboratory features. Clinical data including fever, respiratory distress, diarrhea, rash, etc. as well as laboratory tests including complete blood count, serum glucose level, electrolytes, liver function test, cultures, CD4 lymphocyte count were evaluated. During the study period, 32 HIV positive children were enrolled. The majority of patients were presented with weight loss, prolonged fever, respiratory infection and chronic diarrhea. In this study, salmonella infections as well as streptococcal pneumonia and candida infections followed by, tuberculosis and Pseudomonas aeruginosa infections were the predominant opportunistic infections. Since the number of HIV-positive children has been alarmingly increasing in recent years and perinatal transmission is the most common route of HIV infection in children, essential recommendations for prenatal HIV testing as well as appropriate antiretroviral therapy by HIV infected mothers are needed.

    The international Headache Society (I H S) diagnostic criteria (International classification of headache disorders edition 2- ICHD 2) for headache in children and adults improved the accuracy of migraine diagnoses. However many short duration headaches in children, receive an atypical migraine diagnosis. This study is to diagnose children and adolescents who presented with such atypical migraines of less than one hour duration. 1402 children and adolescents aged 5 to 15 years who presented with recurrent brief activity affected head pain, were studied. Known and common migraine triggers and family history of migraine were recorded in all. All the children studied had moderate to severe headache lasting 5 to 45 minutes which forced them motionless during the attacks (thus fulfilling 2 diagnostic pain features). At least one of the ICHD2 pediatric migraine diagnostic symptoms (nausea / vomiting / photophobia / phonophobia) were present in all. Two additional features were diagnostic of brief migraines in all of them- one of the parents or siblings was a migrainer and one of the common migraine triggers as a precipitating factor. This study concludes that if duration of head pain is less than one hour ,two additional features to be included to diagnose definitive migraine in children and adolescents - one migraine parent or sibling and one of the migraine triggers precipitating the head pain.

    Full Text Available ABSTRACT: BACKGROUND: Learning is not a unitary process involving teacher and student. It also depends on the relationship and interplay of fami lial, psychological, educational, social and economical atmosphere in and around the child. AIM: The present study was done to formulate a diagnostic profile and compare the co-morbidity sta tus in children presenting with poor scholastic performance in a Child Guidance Clinic s et up. SETTINGS AND DESIGN: A sample of 100 children from the age of 4 years to 12 years at tending the Child Guidance Clinic under the department of Paediatrics in a medical college set u p with history of poor scholastic performance was collected. The study design was case study method. METHODS AND MATERIALS: Detailed psychological analysis was done and diagno sis was made by using the ICD – 10 diagnostic guidelines and multi axial diag nostic system. The study population was divided in to failure (group II and non failure (gr oup I groups based on the repetition of grade and the psychiatric morbidity was compared. STATISTICAL ANALYSIS: Statistical analysis was done by SPSS (Statistical Package for the Social Sc iences and chi square test. RESULTS AND CONCLUSIONS: Psychiatric morbidity was present in 42%, developmen tal disorders in 34%, Non psychiatric medical diagnosis in 25% and abnorma l psychosocial situation in 31% of the sample population. Multiple diagnoses were present in 1 6%. Comparison shows that Prevalence of psychiatric co morbidity was more in the failure group than the non failure group. Scholastic backwardness in children is a complex issue, having various causes. Each child’s problem is unique in nature. So a multi disciplinary interventi on is needed at Paediatric level itself.

    Full Text Available Background  Short stature is a manifestation of a wide variety of conditions that some of which may be amenable to timely treatment and a suboptimal growth rate may be an early marker pointing to the cause of growth retardation. This study was conducted to evaluate the diagnostic utility of growth rate in differential diagnosis of children with short stature. Materials and Methods All children between the ages of 2 and 18 years who visited in pediatric endocrinology clinic in a five years period were recruited in a prospective cohort study. Children with standing height Results One hundred forty three patients fulfilled the inclusion criteria. Mean follow up period was 14.4±10.9 months. Etiologies of short stature were: constitutional growth delay (CGD 46.9%, familial short stature (FSS 28.7%, hypothyroidism 4.2%, growth hormone deficiency (GHD 4.2% and miscellaneous causes in 16% of patients.  Mean Z- score for children with constitutional growth delay was -2.3±0.69, in familial short stature was -2.3±0.65 and for other condition was -2.7±1.49. There was a meaningful statistical correlation between growth rate and etiology of short stature (P0.05. Conclusion There was significant difference in growth rate between children with constitutional growth delay and familial short stature in comparing to short stature due to endocrine problem and other etiologies. Assessment of growth rate has some utility in diagnosing the etiology of short stature.

    Full Text Available Introduction: Lung cancer has been the most common cancer in the world and in Belarus. Aim of the research: To evaluate the epidemiology of non-small cell lung cancer and improvements in diagnostics and treatment for the past 11 years in the Brest Region of Belarus. Material and methods: We conducted a retrospective analysis of statistical data (incidence rate, mortality in the regional cancer registry of the Brest oncological clinic since 2000 and assessed survival for 652 adult patients with different stages of non-small-cell lung cancer (NSCLC who underwent surgery in the Thoracic Surgery Department of Brest Regional Hospital in 2002–2010. Results: Lung cancer continues to have the highest incidence rate among malignant neoplasms and because of its high fatality rate is a leading cause of cancer-related mortality in the Brest Region and Belarus. The chest radiography screening programme of lung cancer since 2000 and the implementation of computed tomography (CT- and ultrasonography (USG-guided needle biopsy and VATS LigaSure pulmonary wedge resection for the evaluation of solitary pulmonary nodules has allowed an increase of diagnostic rates and improved the histological confirmation rate of lung cancer in the Brest Region. Multivariate analysis indicates that male sex, age older than seventy and incomplete surgical resection are independent predictors of poor prognosis for postoperative long-term overall survival. Conclusions : Today it is necessary to carry out low-dose spiral computerized diagnostics in the Brest Region, which would detect a greater proportion of asymptomatic lung cancers. Surgical resection remains the only consistent and successful option of a cure for patients with lung cancer.

    BACKGROUND: Outdoor air pollution is a global problem with serious effects on human health, and children are considered to be highly susceptible to the effects of air pollution. OBJECTIVE: To conduct a comprehensive and updated systematic review of the literature reporting the effects of outdoor air pollution on the respiratory health of children in Canada. METHODS: Searches of four electronic databases between January 2004 and November 2014 were conducted to identify epidemiological studies evaluating the effect of exposure to outdoor air pollutants on respiratory symptoms, lung function measurements and the use of health services due to respiratory conditions in Canadian children. The selection process and quality assessment, using the Newcastle-Ottawa Scale, were conducted independently by two reviewers. RESULTS: Twenty-seven studies that were heterogeneous with regard to study design, population, respiratory outcome and air pollution exposure were identified. Overall, the included studies reported adverse effects of outdoor air pollution at concentrations that were below Canadian and United States standards. Heterogeneous effects of air pollutants were reported according to city, sex, socioeconomic status and seasonality. The present review also describes trends in research related to the effect of air pollution on Canadian children over the past 25 years. CONCLUSION: The present study reconfirms the adverse effects of outdoor air pollution on the respiratory health of children in Canada. It will help researchers, clinicians and environmental health authorities identify the available evidence of the adverse effect of outdoor air pollution, research gaps and the limitations for further research.

    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.)

    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.

    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.

  8. Molecular methods for the detection of human papillomavirus infection: new insights into their role in diagnostics and epidemiological surveillance

    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.

    Imaging-matching is an important research area in imaging informatics. We have developed and evaluated a novel diagnostic support tool (DST) based on medical image matching using MR brain images. The approach consists of two steps, database generation and image matching. The database contains pre-diagnosed MR brain images. As the images are added to the database, they are registered to the 3D Talairach coordinate system. In addition, regions of interests (ROI) are generated, and image-processing techniques are used to extract relevant image parameters related to the brain and diseases from the ROIs and from the entire MR image. The second step is to retrieve relevant information from the database by performing image matching. In this step, the physician first submits a query image. The DST computes the similarity between the query image and each of the images in the database, and then presents the most similar images to the user. Since the database contains pre-diagnosed images, the retrieved cases tend to contain relevant diagnostic information. To evaluate the usefulness of the DST in a clinical setting, pediatric brain diseases were used. The database contains 2500 pediatric patients between ages 0 and 18 with brain Magnetic Resonance (MR) images of known brain lesions. A testbed was established at the Children's Hospital Los Angeles (CHLA) for acquiring MR images from the PACS server of patients with known lesions. These images were matched against those in the DST pediatric brain MR database. An expert pediatric neuroradiologist evaluated the matched results. We found that in most cases, the image-matching method was able to quickly retrieve images with relevant diagnostic content. The evaluation method and results are given.

    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.

    To compare the value of hip roentgenograms and bone scintigraphy in Legg-Calve-Perthes (LCP) disease, a double blind study was done in 153 children, of whom 51 had LCP. Each procedure was read separately by two investigators who had no knowledge of clinical data. Variations across investigators were less significant for roentgenograms than for bone scans. Agreement on diagnosis between the two investigators was 95% for roentgenograms, against only 89% for bone scans. As regards the detailed analysis of each separate finding upon bone scintigraphy and assessment of this procedure's prognostic value, major discrepancies occurred between the two investigators. Diagnostic accuracy was very similar for the two procedures. Both bone scintigraphy and roentgenography showed a 0.86 sensitivity. Specificities were 0.93 and 0.99 respectively. For the subgroup of patients with early-stage LCP disease (33 cases), scintigraphy identified a slightly greater number of cases than roentgenography (0.88 and 0.76 respectively). Some disagreements between our results and those previously published in the literature may stem from biases such as the criteria for entering patients into the study or for establishing the final diagnosis. Roentgenography is obviously the first procedure to perform in a child with a painful hip or a limp. However, the results may be inconclusive in early-stage disease. In such cases, scintigraphy is needed and often avoids unnecessary traction or diagnostic delay.

    2012-01-01

    Two bereavement-related disorders are proposed for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V): Adjustment Disorder Related to Bereavement, to be located in the main body of the text as an official diagnostic entity; and Bereavement-Related Disorder, including a Traumatic Death Specifier, to be located in the Appendix as an invitation for further research. These diagnoses currently do not include developmentally informed criteria, despite the importance of developmental processes in the ways children and adolescents grieve. In this article, we draw upon a selective review of the empirical literature and expert clinical knowledge to recommend developmentally informed modifications and specifiers of the proposed criteria for both bereavement disorders and strategies to improve future research. This article is derived from an invited report submitted to the DSM-V Posttraumatic Stress Disorder, Trauma, and Dissociative Disorders Sub-Work Group, and suggested modifications have received preliminary approval to be incorporated into the DSM-V at the time of this writing. Adoption of these proposals will have far-reaching consequences, given that DSM-V criteria will influence both critical treatment choices for bereaved youth and the next generation of research studies.

    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

    Full Text Available Context: Community associated methicillin resistant Staphylococcus aureus (CA-MRSA cause serious skin and soft tissue infections including necrotizing fasciitis and necrotizing pneumonia. Production of Panton Valentine Leucocidine (PVL toxin is implicated in its enhanced virulence. A variant of epidemic MRSA-15 (EMRSA-15 which produces PVL toxin has been isolated and characterized by pulsed-field gel electrophoresis (PFGE method from the Indian population both in hospital and community settings. Aims: Identify the epidemiological type of MRSA colonizing the anterior nares of school children in Udupi taluk. Settings and Design: The study population included children of the age group of 5-16 years belonging to the Udupi taluk of Karnataka, India. A total of 1503 children were screened for MRSA colonization during July 2009 to December 2010. Materials and Methods: PVL assay, Staphylococcal Cassette Chromosome (SCC mec typing and PFGE typing were carried out with all the MRSA isolates. Statistical Analysis Used: Frequency distribution of different variables was assessed by SPSS. Results: Among the 1.1% of MRSA, 58.8% (10/17 of isolates were positive for pvl and 41.7% (7/17 were identified as SCC mec type IV. PFGE patterns of all the strains were identical with Indian variant EMRSA-15; however they were different from classical EMRSA-15 in 3-4 bands. Conclusions: The Indian variant EMRSA-15 gains much epidemiological relevance owing to the acquisition of pvl gene. In spite of low prevalence of nasal colonization of MRSA, emergence of the virulent Indian variant EMRSA-15 in our community is a worrisome fact to be reckoned with.

    The aim of this study is to describe the epidemiological and microbiological characteristics and outcome of children with septicemia at the Charles de Gaulle University Pediatric Hospital of Ouagadougou to help improve probabilistic antibiotic therapy in this type of infection. This retrospective descriptive study covered all the children from 0 to 15 years old seen over a period of 7 years in any hospital department with suspected bacteriemia and for whom the bacteriology laboratory performed a blood culture. During the study period, the laboratory received 842 requests for blood cultures and found 154 (18.3%) of them to be positive. Files for 81 of the 154 patients could be found and examined. The distribution according to age showed septicemia was most frequent among those aged 6-15 years (61.7% of the cases). Microbial identification showed the dominant species to be Salmonella enterica (serovars paratyphi and typhi) (58%) followed by Staphylococcus aureus (12.3%). The salmonella isolates had a high rate of resistance to amoxicillin, chloramphenicol and cotrimoxazole. Staphylococci were always sensitive to the antibiotics with which they were tested, although to a lesser extent for penicillin G. All patients routinely received antibiotic treatment, and 81.5% (n=66) were cured (5 children died and 10 left the hospital against medical advice). This study shows that the bacterial epidemiology of septicemia in our setting is dominated by salmonella. Trends in bacterial resistance to antibiotics showed that common antibiotics such as amoxicillin and cotrimoxazole are no longer acceptable as probabilist therapy here. They should be replaced in this type of infection by injectable third generation cephalosporin alone or combined with aminoglycosides.

    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.

    Full Text Available A malocclusion is a misalignment of teeth or incorrect relation between the teeth of the two dental arches. The aim of this presentation is to show the percentage of the children with malocclusions and comparison between children with mild and severe malocclusions from rural and urban regions Materials and methods: 1200 children between 5 and 6 years old from North-eastern Bulgaria (600 urban and 600 rural were examined. WHO standards were applied and the data was collected in WHO statistic forms, which were modified accordingly. The children were divided in 3 groups-healthy, with mild and with severe malocclusions according to Angles classification. Results: More than a half of the urban children are healthy – 51,5% and the biggest percentage of the malocclusions are mild – 31,3%, only 17,2% have severe malocclusions. The rural children are without malocclusions – 23,8% and – 39,2% of them are with severe orthodontic deformations. Relative shares of children with malocclusions from the urban – 48,5% and rural regions – 76,2% The relative share of the healthy children from both urban and rural regions is 37,7%. The relative share of the children with malocclusions from urban and rural regions is 62,3%. Conclusion: A little percent of the rural children are without malocclusions and more of them are with severe ones. We suggest that specialist have to work on better prevention in these regions.

    The array of tests that can be used for diagnosis of Helicobacter pylori infection is large, and it can be confusing to define which test to use particularly in children where results may not be comparable to those obtained in adult patients. Using PubMed, we reviewed the English literature from January 1999 to May 2009 to identify articles that determined sensitivity and specificity of H. pylori invasive and non-invasive diagnostic tests in children. We excluded articles that presented a review of the literature, abstracts, case reports, or series where children's results could not be separated from adult populations. Of the tissue based methods, rapid urease tests have better sensitivity than histology to detect presence of H. pylori; however, histology can detect the pathology associated with disease including gastritis, intestinal metaplasia, and other conditions that could be the cause of the child's symptoms. Culture of gastric tissues or stool has 100% specificity but sensitivity is low. Of the serologic tests, immunoblot has the best sensitivity. The urea breath tests have >75% sensitivity for detection of H. pylori before and after treatment. Immunoassays in stool using monoclonal antibodies have >95% sensitivity for detection of H. pylori before and after treatment. PCR testing can be performed in tissue and stool samples and can detect genes associated to antibiotic resistance. In summary, the current commercial non-invasive tests have adequate sensitivity and specificity for detecting the presence of H. pylori; however, endoscopy with histopathology is the only method that can detect H. pylori and lesions associated with the infection.

    The prevalence of goitre in areas with mildly excessive iodine in drinking-water is still under debate. The aim of the present study was to explore the prevalence of goitre and its epidemiological characteristics in these areas using WHO criteria. To this end, three towns with a median water iodine (MWI) of 150-300 μg/l were selected randomly in Hengshui City of Hebei Province of China, and one town with a MWI of 105 μg/l was chosen as a control. A total of 452 children in the three towns and 120 children in the control town were randomly selected to measure thyroid volume (T vol) by ultrasound. The goitre status of these children was judged using the criteria recommended by the WHO. The overall goitre prevalences in the three towns were 24·6 % (111/452) by age-specific T vol and 33·0 % (149/452) by body surface area (BSA)-adjusted T vol, which were significantly higher than that in the control town by both age-specific T vol (14·0 % (17/120), P= 0·015) and BSA-adjusted T vol (17·5 % (21/120), P= 0·001). Significant differences were found neither in goitre prevalences across sex by both age-specific T vol (P= 0·078) and BSA-adjusted T vol (P= 0·692) nor in that across age group by both BSA-adjusted T vol (P= 0·461) and age-specific T vol (P= 0·183). The present study found a high prevalence of goitre in children living in areas with mildly excessive iodine in drinking-water in Hebei Province. No significant differences were found in goitre prevalences across sex and age group. These results suggest that the T vol reference values recommended by the WHO could be too low for Chinese children.

    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 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.

    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 Introduction: The integral part of the treatment of pediatric oncological patients is a range of diagnostic and therapeutic procedures. These procedures are often associated with the fear and anxiety of the suffering child. We investigated whether a psychological preparation through drama therapy and the therapeutic puppet may reduce the anxiety related to diagnostic and therapeutic procedures in the preschool or early school children suffering from cancer.Methods: Twenty consecutive pediatric patients of preschool and early school age, with the diagnosis of lymphoblastic leukemia, were included in the study. The patients were alternatingly assigned to experimental or control group, and subjected or not subjected to drama therapy, respectively. We measured the changes in heart rate, blood pressure and respiratory rate as indicators of anxiety and fear, before and after the diagnostic or therapeutic procedures.Results: Heart rate, blood pressure, and respiratory rate in pediatric oncological patients before and after the diagnostic or therapeutic procedure were significantly lower in the experimental group of patients.Conclusion: Our results show that psychological preparation using drama therapy and therapeutic puppet reduced the fear and anxiety related to diagnostic or therapeutic procedures in pediatric oncological patients.Key words: drama therapy; therapeutic puppet; children; oncology; psychology

    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.

    1994-04-01

    Fecal specimens were obtained on 3 occasions at 10-12 wk intervals from 315 children in 3 rural villages in Zimbabwe and from 351 children in the high-density suburbs of an adjacent small town. Specimens were examined qualitatively and quantitatively for eggs of Hymenolepis nana, and these were found in 142 (21%) children. Infections occurred more frequently in younger children in the urban area but in older children in rural areas. The prevalence in urban areas (24%) was higher than in rural areas (18%), and in urban areas infection correlated with low "hygiene scores" (determined by observation) and with the presence in the household of an infected sibling. The prevalence of infection in the 3 rural communities did not correlate with availability of water, number of households per toilet, with low "hygiene scores," or with the presence of an infected sibling. Treatment with a single oral dose of 15 mg/kg praziquantel cured 84% of the infected children. New or reinfections occurred more frequently in households that had an infected sibling in an urban but not rural setting. The study demonstrates distinct differences in the transmission of H. nana infection in rural and urban communities. The data suggest intrafamily transmission in urban areas, particularly in households with poor hygiene behavior, leading to primary infection early in life. In rural areas, the prevalence of infection and the incidence of reinfection were highest in children of school age, and there was little evidence for intrafamily transmission of the parasite.

    2015-08-01

    Electrographic seizures and electrographic status epilepticus are common in children with critical illness with acute encephalopathy, leading to increasing use of continuous EEG monitoring. Many children with electrographic status epilepticus have no associated clinical signs, so EEG monitoring is required for seizure identification. Further, there is increasing evidence that high seizure burdens, often classified as electrographic status epilepticus, are associated with worse outcomes. This review discusses the incidence of electrographic status epilepticus, risk factors for electrographic status epilepticus, and associations between electrographic status epilepticus and outcomes, and it summarizes recent guidelines and consensus statements addressing EEG monitoring in children with critical illness. This article is part of a Special Issue entitled "Status Epilepticus".

    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

    Ninety-nine children admitted to the Instituto Materno Infantil de Pernambuco with severe malnutrition from May 1999 to May 2000 were investigated in a cross-sectional study focusing on key epidemiological and clinical variables. The majority of the children (88.9%) were less than 6 months of age, 42.4% had a history of low birth weight, and 36.4% were premature. Some 19.2% had never been breastfed, and 49.5% had been breastfed for less than 2 months. Some 15.2% of the mothers were illiterate. Most of the families (86.1%) had incomes less than twice the minimum wage (approximately US$150/month), and 51.5% had migrated from rural areas. Only 26.3% of the homes had running water, and 40.4% lacked sewage disposal facilities. Diarrhea was the reason for hospital admission in 55.6% of the cases. Hospital mortality was 34.3% in this group.

    The most critical phase of exposure to schistosomal infection is the infancy, because of the more frequent contact with contaminated water and the immaturity of the immune system. One of the most severe presentations of this parasitosis is the involvement of the spinal cord, which prognosis is largely dependent on early diagnosis and treatment. Reports on this clinical form of schistosomiasis in children are rare in the literature. We present here the clinical-epidemiological profile of schistosomal myeloradiculopathy (SMR) from ten children who were admitted at the Instituto Materno-Infantil de Pernambuco over a five-year period. They were evaluated according to an investigation protocol. Most of these patients presented an acute neurological picture which included as the main clinical manifestations: sphincteral disorders, low back and lower limbs pain, paresthesia, lower limbs muscle weakness and absence of deep tendon reflex, and impairment of the gait. The diagnosis was presumptive in the majority of the cases. This study emphasizes the importance of considering the diagnosis of SMR in pediatric patients coming from endemic areas who present a low cord syndrome, in order to start the appropriate therapy and avoid future complications.

    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.

    We investigated the knowledge level and risk factors for pediatric unintentional burns in rural Southwest China with an aim to provide basic evidence for the prevention strategies. A stratified sampling method was used to recruit 1842 rural children from 9 schools. Self-reported burns during the past 12 months and relevant risk factors were collected by questionnaires. The burn incidence of all surveyed children was 12.7% (95% confidence interval [95% CI] 11.2–14.2%). We found that burn incidence had a trend to increase with the increasing school grade level and a trend to decrease with increasing knowledge scores on burns. The top two causes of burns were hot liquids (36.3%) and hot object (29.5%). More than 30% of children had little knowledge about preventive measures and how to give first-aid after burns. The main risk factors for burns included female gender, left-behind children by parents who were working in cities, and poor mother school education level. As the incidence of pediatric unintentional burns was high in rural southwest China, schools, families, and local public health agencies should put efforts into health education targeting burn prevention and first-aid measures after burns, particularly in “left-behind” children and those with mothers with poor education.

    Renal colic is a common reason for presentation to emergency departments, and imaging has become fundamental for the diagnosis and clinical management of this condition. Ultrasonography and particularly noncontrast computed tomography have good diagnostic performance in diagnosing renal colic. Radiologic management will depend on the tools available at the center and on the characteristics of the patient. It is essential to use computed tomography techniques that minimize radiation and to use alternatives like ultrasonography in pregnant patients and children. In this article, we review the epidemiology, clinical and radiologic presentations, and clinical management of ureteral lithiasis.

    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.

    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

    A prospective observational study was carried out at the Emergency Department, Hospital Kuala Lumpur to determine the proportion of accidental head injury among children and the circumstances of injury. The study was carried out from November 1993 to January 1994 on all children below 14 years who presented to the Emergency Department with accidental head injury. Accidental head injury made up (4.75%) of all cases seen at the Casualty Department. The ratio of boys to girls was 2:1. The mean age of head injured children was 5.2 (S.D. 3.63) years. The leading cause of head injury was fall (63%) followed by road traffic accidents (RTA) in (30.7%) while the rest were due to 'impact' (injury caused by flying object or missiles) injuries. More than half (54.4%) of those injured in RTA were pedestrians. Pedestrian injury was particularly important in the 5-< 14 years age group, where adult supervision was lacking in two thirds of the children. None of the patients who were involved in vehicle-related injuries had used a suitable protective or restraining device. All three patients who died were from this group. This study emphasises the need for stricter enforcement of laws related to the use of protective devices and measures to decrease child pedestrian injury. The issues of lack of adult supervision, both in and outside the home need to be addressed.

    Insomnia is the predominant sleep concern in children with autistic spectrum disorder (ASD), and its nature is most likely multifactorial, with neurochemical (abnormalities in serotonergic transmission or melatonin levels), psychiatric (anxiety), and behavioral (poor sleep habits) etiological factors involved. Children with ASD experience sleep problems similar to those of typically developing children, although the prevalence is markedly higher, occurring in 44-83% of school-aged children with ASD. Caregivers usually report that insomnia is the most frequent sleep disorder, described as disorders of initiating and maintaining sleep, restless sleep, bedtime resistance, co-sleeping, alterations of sleep hygiene, and early awakenings in the morning. Many actigraphic studies have added information on sleep disorders, confirming the questionnaire findings in the majority of cases. There are relatively few polysomnographic data for ASD, compared with questionnaire studies, and most of these studies reported a reduction in total sleep time and more undifferentiated sleep in the youngest patients. These findings were associated with several sleep microstructure alterations during rapid eye movement (REM) sleep, and with non-REM (NREM) sleep microstructure changes that appeared to be related to cognitive impairment rather than to the autistic core. Moreover, few data about other less frequent sleep disorders, such as periodic limb movements disorder and obstructive sleep apnea syndrome, bruxism, and the influence of epilepsy and EEG abnormalities, are available. Both pharmacologic and behavioral interventions have been suggested for the treatment of sleep problems in autistic children. The most common types of behavioral interventions are complete extinction (removing reinforcement to reduce a behavior) and various forms of graduated extinction. Melatonin has shown promising results in the treatment of insomnia in children with ASD. Although controlled studies are limited

    Full Text Available In Sub-Saharan Africa, infectious diarrhea is a major cause of morbidity and mortality. A case-control study was conducted to identify the etiology of diarrhea and to describe its main epidemiologic risk factors among hospitalized children under five years old in Bangui, Central African Republic.All consecutive children under five years old hospitalized for diarrhea in the Pediatric Complex of Bangui for whom a parent's written consent was provided were included. Controls matched by age, sex and neighborhood of residence of each case were included. For both cases and controls, demographic, socio-economic and anthropometric data were recorded. Stool samples were collected to identify enteropathogens at enrollment. Clinical examination data and blood samples were collected only for cases.A total of 333 cases and 333 controls was recruited between December 2011 and November 2013. The mean age of cases was 12.9 months, and 56% were male. The mean delay between the onset of first symptoms and hospital admission was 3.7 days. Blood was detected in 5% of stool samples from cases. Cases were significantly more severely or moderately malnourished than controls. One of the sought-for pathogens was identified in 78% and 40% of cases and controls, respectively. Most attributable cases of hospitalized diarrhea were due to rotavirus, with an attributable fraction of 39%. Four other pathogens were associated with hospitalized diarrhea: Shigella/EIEC, Cryptosporidium parvum/hominis, astrovirus and norovirus with attributable fraction of 9%, 10%, 7% and 7% respectively. Giardia intestinalis was found in more controls than cases, with a protective fraction of 6%.Rotavirus, norovirus, astrovirus, Shigella/EIEC, Cryptosporidium parvum/hominis were found to be positively associated with severe diarrhea: while Giardia intestinalis was found negatively associated. Most attributable episodes of severe diarrhea were associated with rotavirus, highlighting the urgent

There was increase in the number of people with nodules in the territories exposed to radioactive fallout after Chernobyl accident in comparison to the territories without such pollution – 57.3%/42.4% as well as malignant tumors among them (5.2%/2.7% Comparison of thyroid palpation and ultrasound in detection of thyroid nodules revealed that thyroid nodules of 10 mm were detected only in every 10th patient by means of pal pation: and nodules of 11–15 mm in every 4th patient, comparing to ultrasound data of the same patients’ group. Malignant tumors were detected on cytology in 2.9% of thyroid nodules less than 2 cm (30171 patients and in 1.9% of thyroid nodules larger than 2 cm (15 656 patients. At the same time the frequency of regional lymph node metas tases was significantly higher in patients with thyroid nodules larger than 2 cm (34.8%, than in patients with nod ules less than 2 cm – 18.3%. Only one malignant tumor was detected among 358 patients with autonomously func tioning nodules. Risk groups with higher rate of malignancy were patients living in the areas with Chernobyl’s fall out, and patients in whom nodules with “suspicious” sonographic features were revealed (rough edges, capsule inva sion, microcalcifications. Patients with high risk of malignant transformation should be submitted to FNAB regard less of thyroid nodule size.

    Full Text Available &lt;b&gt;Purpose:&lt;/b&gt; Early diagnosis and treatment of acute pyelonephritis in children is of special importance in order to prevent serious complications. This study was conducted to determine the diagnostic value of serum interleukin (IL-6 and IL-8 in children with acute pyelonephritis. &lt;b&gt;Methods:&lt;/b&gt; Eighty seven patients between 1 month to 12 years old with urinary tract infection (UTI were divided into 2 groups based on the result of 99m-technetium dimercapto-succinic acid (DMSA renal scan: acute pyelonephritis (n=37 and lower UTI (n=50 groups. White blood cell (WBC count, neutrophil (Neutl count, erythrocyte sedimentation rate (ESR, C-reactive protein (CRP concentration, platelet count, and serum IL-6 and IL-8 concentrations of both groups were measured and compared . &lt;b&gt;Results:&lt;/b&gt; There was a significant difference between two groups regarding WBC count, Neutl count, ESR, and CRP concentration (P&lt;0.05. In addition, the difference between the two groups regarding serum IL-6 and IL-8 concentrations was not significant (IL-6, 60 and 35.4 pg/mL and IL-8, 404 and 617 pg/mL, respectively. The sensitivity and specificity of serum IL-6 and IL-8 for diagnosis of acute pyelonephritis were 73%, 42% and 78%, 32%, respectively. Sensitivity, specificity, negative and positive predictive values of serum IL-6 and IL-8 were less than those of acute phase serum reactants such as CRP. &lt;b&gt;Conclusion:&lt;/b&gt; This study showed that there was no significant difference between acute pyelonephritis and lower UTI groups regarding serum IL-6 and IL-8 levels. Therefore, despite confirming results of previous studies, it seems that IL-6 and IL-8 are not suitable markers for differentiating between acute pyelonephritis and lower UTI.

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.

    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

No strains of EPEC belonging to serogroups 086, 0126, and 0158 were found. Among the samples in which EPEC strains were isolated, 15.0 per cent were children living in dwellings which had piped systems of water supply and drain, whereas with regard to those living in houses without such facilities, this percentage raised to 24 per cent. Similar results were found when the availability of water supply of drainage were taken separately.

    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.

    Mothers with hepatitis C virus (HCV) and HIV coinfection are the major source of HCV/HIV coinfection in infancy and childhood. There is no known intervention capable of interrupting HCV spread from mother to child, while the majority of infant HIV infections occurring in the developed world can be prevented by antiretroviral prophylaxis in the mother and child, elective caesarean section, and formula-feeding. In the era preceding treatment of HIV infection with highly active antiretroviral therapy, HCV coinfection was of little concern because the short-term survival of patients with HIV infection prevented the slowly developing consequences of chronic hepatitis C. As the life expectancy of patients with HIV infection increased with therapy, HCV has emerged as a significant pathogen. Several lines of evidence in adult patients suggest that liver disease may be more severe in patients coinfected with HIV and that progression of HIV disease may be accelerated by HCV coinfection. Whether coinfected children may share these clinical patterns remains a matter of speculation. Chronic hepatitis C in otherwise healthy children is usually a mild disease; liver damage may be sustained and fibrosis may increase over the years, suggesting slow progression of the disease. Interferon-alpha has been the only drug used in the past decade to treat hepatitis C in children and adolescents, with average response rates of 20%. Preliminary results of treatment with interferon-alpha and ribavirin suggest that the efficacy would be greater with combined therapy. These treatment protocols have not yet been applied to children coinfected with HIV, but the increasing number of long-term survivors will probably prompt further investigation in the near future. At present, treating HIV disease and monitoring HCV infection and hepatotoxicity induced by antiretroviral drugs seem to be the more reasonable approach to HCV/HIV coinfection in childhood.

    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.

    We report the results of pneumococcal meningitis surveillance conducted at the Provincial Pediatric Hospital of Posadas, Misiones (Argentina), before the conjugate vaccine was introduced into the national vaccination schedule. Between January 1994 and December 2009, 167 cases of Streptococcus pneumoniae meningitis were diagnosed in children aged 1 month to 15 years. The attack rate/100,000 children ranged from 19.2 (1997) to 4.3 (2009), with a mean of 10.6 and a tendency to decrease (y=-0.689x+16.52). The number of cases per 100,000 children decreased from 146.6 to 34.8 and particularly involved the group of children aged 1 to 11 months (94/167, 56%). Thirty point seven percent (30.7%) (46/150) of the isolates were resistant to penicillin whereas 16.7% (25/150) were non-susceptible to cefotaxime. β-lactam resistance increased as from 1997 and began to decline in 2005. Nineteen serotypes were detected; type 14 was predominant and accounted for 32% (40/125). Eighty four point eight percent (84.8%) of the isolates were circumscribed to nine serotypes: 14, 5, 1, 7F, 18C, 6B, 9N, 9V and 4. Theoretical coverage for patients aged 2 years was 84.1% (74/88) and 83.8% (31/37) for the 10-valent vaccine and 89.8 % (79/88) and 83.8% (31/37) for the 13-valent vaccine respectively. Penicillin resistance was restricted to 8 serotypes (14, 6B, 6A, 9V, 4, 23B, 19A1) and nonsusceptibility to cefotaxime was circumscribed to 3 serotypes (14, 9V and 1). This study will allow to evaluate the impact of the implementation of conjugate vaccines on our area.

    Post-traumatic stress disorder (PTSD) is a common psychiatric condition in childhood and adolescence. Rates vary widely depending upon the type of trauma exposure. Interpersonal traumas, such as rape or physical abuse, are more likely to result in PTSD than exposure to natural or technological disaster. Clinical presentations are exceedingly complex and children with PTSD are at increased risk of having comorbid psychiatric diagnoses. Because of its complexity and frequent occurrence with other disorders, assessment of PTSD necessitates a broad-based evaluation utilizing multiple informations and structured instruments specific to the symptoms of PTSD in youth. Cognitive-behavioral therapy (CBT) is the treatment of first choice. Pharmacological agents for PTSD treatment have received little empirical investigation in childhood. Pharmacological treatment is used to target disabling symptoms of the disorder, which limit psychotherapy or life functioning, by helping children to tolerate working through distressful material in therapy and life. Pharmacological treatment should be based on a stepwise approach utilizing broad spectrum medications such as the selective serotonin reuptake inhibitors as first-line agents. Comorbid conditions should be identified and treated with appropriate medication or psychosocial interventions. Treatment algorithms are provided to guide rational medication strategies for children and adolescents with PTSD, subsyndromal PTSD, and in PTSD that is comorbid with other psychiatric conditions of childhood. Reduction in even one debilitating symptom of PTSD can improve a child's overall functioning across multiple domains.

    Objective: To estimate the prevalence of intestinal parasites and their species in Afghan school children and to establish appropriate treatment methods for detected pathogens. Methods: Parasitological examination of stool samples collected from 1369 children aged 8-18, students of the Jahan Malika High School in Ghazni Province in eastern Afghanistan, was conducted in the period November 2013-April 2014. Three stool samples were collected from each patient every second day; the samples were fixed in 10% formalin and tested by light microscopy using the methods of direct smear in Lugol’s solution, decantation in distilled water, and Fülleborn’s flotation. Results: Of 535 examined children (39.1% of the study group) were infected with nematodes (n=324), cestodes (n=118), trematodes (n=12), and protozoa (n=228), 132 were diagnosed with co-infections (mainly ascariasis+giardiasis, ascariasis+hymenolepiasis) and received single or combined therapy. Conclusions: The Afghan community is an example of population characterized by a high rate of parasitic infections. Owing to high prevalence of multiple infections among inhabitants of Afghanistan, it seems that a mass deworming campaign with a single-dose chemotherapy may prove ineffective in eradicating intestinal parasites in the local population.

    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.

    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.

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.

    2005-02-01

    Full Text Available In the few cases of acute childhood diarrhea that require antimicrobial therapy, the correct choice of the drug depends on detailed previous knowledge of local strains. In order to establish such parameters in our city, we reviewed the results of all 260 positive stool cultures of children between 0 and 15 years of age during two years at a pediatric tertiary care facility in Salvador, Brazil. Bacterial strains had been presumptively identified by culturing in selective media and by biochemical testing, and their antimicrobial susceptibility patterns were automatically detected by the MicroScan Walkaway System. Data about patients' sex and age, monthly distribution of the cases, pathogens isolated and their antimicrobial resistance patterns were recorded. Males corresponded to 55.4% of our sample, and most of our patients (42.7% were between one and four years of age. Shigella was the commonest pathogen, being found in 141 (54.3% cultures, while Salmonella was found in 100 (38.4% cultures and Enteropathogenic E. coli in 19 (7.3%. Salmonella was the main causal agent of diarrhea in children younger than five years old, whereas Shigella was the most frequent pathogen isolated from the stools of children between five and 15 years old. The peaks of incidence correspond to the periods of school vacations. Shigella specimens presented a very high resistance rate to trimethoprim-sulfamethoxazole (90.1% and to ampicillin (22.0%, while Salmonella presented very low resistance rates to all drugs tested. These data are useful for practitioners and they reinforce the need for continuous microbiological surveillance.

    The aim of this study was to assess the Staphylococcus aureus nasal carriage rate in healthy children all over Hungary and to specify some risk factors, the antibiotic resistance patterns of the bacteria, and their genetic relatedness. In total, 878 children (aged 3-6 years) were screened at 21 day-care centers in 16 different cities in Hungary, between February 2009 and December 2011. Samples taken from both nostrils were cultured on blood agar, and suspected S. aureus isolates were identified by β-hemolysis, catalase positivity, clump test, and nucA PCR. Methicillin-resistant strains were screened by mecA and mecC PCR. Antibiotic susceptibility was determined by agar dilution or gradient test strips. Pulsed-field gel electrophoresis was used for genotyping. S. aureus carriage rate was found to be 21.3%, which correlates well with international data. We found no statistically significant correlation between the gender or the sibling status and S. aureus carriage. All isolates were sensitive to oxacillin, trimethoprim-sulfamethoxazole, and mupirocin. The resistance rates for erythromycin, ciprofloxacin, clindamycin, gentamicin, and tetracycline were 7.5%, 0.5%, 1.1%, 3.7%, and 4.3%, respectively. The isolates showed very high genetic diversity. In summary, carried S. aureus isolates are more sensitive to antibiotics compared with clinical isolates in Hungary, and methicillin-resistant S. aureus carriage rate is very low yet.

    The incidence of dysphonia among children and adolescents is evaluated internationally at 6 % to 25 %. Nonetheless, hoarseness as a leading symptom among children is often insufficiently recognized by their parents/attachment figures, by the young patients themselves, and even by physicians. In an overview, the hereditary and acquired organic and functional causes - including secondary organic lesions of the vocal folds - their pathomechanisms and the symptoms typical for this age group are presented. For diagnostics suitable for these age groups and developmental stages, modern methods of laryngoscopy (including stoboscopy and real-time laryngoscopy), of functional diagnostics of vocal capacity and quality as well as anamnestic and psychometric procedures for the investigation of possible psychosomatic genesis are available. Frequent therapeutic measures are vocal hygienic counseling and psycho- and family dynamic therapies. Vocal exercise treatments are particularly employed for the consequences of laryngeal surgery and with voice techniques unfavorable as a precondition for increased vocal activity. Operative measures in the sound-producing areas of the vocal apparatus and in the framework of plastic reconstruction concentrate on the optimizing of vocal capacity and quality. In clinical routine, symptoms of dysphonia in children and adolescents should be consciously registered, and any long-term hoarseness, in this age group as well, should be examined by specialized physicians using the methods suitable to the age group and the developmental stage. When the appropriate indications are present, all of the therapeutic options currently available should be discussed.

    Full Text Available 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.

    There is a critical need for improved diagnosis of tuberculosis in children, particularly in young children with intrathoracic disease as this represents the most common type of tuberculosis in children and the greatest diagnostic challenge. There is also a need for standardized clinical case definitions for the evaluation of diagnostics in prospective clinical research studies that include children in whom tuberculosis is suspected but not confirmed by culture of Mycobacterium tuberculosis. A panel representing a wide range of expertise and child tuberculosis research experience aimed to develop standardized clinical research case definitions for intrathoracic tuberculosis in children to enable harmonized evaluation of new tuberculosis diagnostic technologies in pediatric populations. Draft definitions and statements were proposed and circulated widely for feedback. An expert panel then considered each of the proposed definitions and statements relating to clinical definitions. Formal group consensus rules were established and consensus was reached for each statement. The definitions presented in this article are intended for use in clinical research to evaluate diagnostic assays and not for individual patient diagnosis or treatment decisions. A complementary article addresses methodological issues to consider for research of diagnostics in children with suspected tuberculosis.

    Full Text Available Background - The main goal of this paper is to investigate the frequency, clinical profile, and endoscopic findings of children and teenagers submitted to colonoscopies. Methods - Patients of below 18 years of age, diagnosed with polyps by means of colonoscopies at two reference centers of pediatric endoscopy were followed-up between 2002 and 2012. The clinical variables evaluated in this study included: gender, recommendation of colonoscopy, associated signs and symptoms, age of onset of symptoms, age at identification of the polyp, interval of time between the onset of symptoms and the endoscopic diagnosis of colonic polyps, and family history of intestinal polyposis and/or colorectal cancer. The characteristics of the polyps also included: number, morphological type, histology, and distribution. Polyposis syndromes were also investigated. Results - From the 233 patients submitted to colonoscopies, polyps were found in 74 (31.7% patients, with a median age of 6.6 years, of which 61% were male. Juvenile polyps were identified in 55 (74% patients, with 7 (9% characterized within the criteria for juvenile polyposis. Patients with intestinal polyposis syndromes were diagnosed in 35% of the patients. The most frequent clinical presentation was hematochezia. Abdominal pain with acute episodes of intestinal partial obstruction or intussusception with emergency laparotomy was observed in the majority of Peutz-Jeghers syndrome patients leading to an increased morbidity. Conclusions - Even though juvenile colonic polyps are the most frequent type of diagnosed polyps, the present study identified a significant level of children with polyposis syndromes (35%, associated with a higher morbidity of these individuals.

    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). Conclusions: The current COG risk group

    Background Tinea capitis remains a prevalent health problem among school-aged children. Objective To estimate the prevalence of tinea capitis among primary school students, in Fayoum, Egypt with identification of etiological agents in both public and private primary schools. Methods A cross-sectional study was conducted in twelve primary schools. The students were selected from different grades with a total number of 12,128 students. Hair and scalp were clinically examined for any lesions that may suspect tinea capitis and mycological samples were collected for direct microscopy and culture. Results The prevalence of tinea capitis in the study group was 0.4% and higher in public than private schools (73.5% versus 26.5% respectively). Boys were more affected than girls with boy to girls' ratio 5:1. Intrafamily history of infection was present in 40.8% of tested group while 51% showed low social standard profile. Mycological culture revealed that Microsporum canis was the predominant isolated organism followed by M. audouinii (52% and 36% respectively). Conclusion M. canis is replacing Trichophyton violaceum as an etiology for tinea capitis in Egypt with lower prevalence rate than reported previously. PMID:28223741

    Anomalous origin of the left coronary artery from the pulmonary artery is a rare congenital anomaly. It is important to demonstrate the anomalous origin of the left coronary artery and its course before surgery. To explore the clinical diagnostic use of multidetector CT coronary angiography in detecting anomalous origin of the left coronary artery from the pulmonary artery in children. Nine children (2 boys, 7 girls) ages 2 months to 9 years with surgically confirmed anomalous origin of the left coronary artery from the pulmonary artery were studied. Clinical data, transthoracic echocardiography and CT coronary angiography images were retrospectively analyzed. Transthoracic echocardiography correctly diagnosed anomalous origin of the left coronary artery from the pulmonary artery in 7 of 9 patients (95% CI: 40-97%). CT coronary angiography revealed the anomalous origin of the left coronary artery in all children (95% CI: 66-100%). In a 4-year-old girl and a 9-year-old girl, CT coronary angiography showed dilation of the right coronary artery and collateral circulation between the right and the left coronary arteries. CT coronary angiography is a useful method to show the anomalous origin of the coronary artery in children with anomalous origin of the left coronary artery from the pulmonary artery, especially for patients in whom origin of the left coronary artery cannot be detected by transthoracic echocardiography.

    Speech-language pathologists experience uncertainty about how to interpret standardized assessment results for Indigenous Australian children. There are risks for inappropriate diagnosis: both over- and under-diagnosis of language impairment may occur due to a convergence of linguistic features which causes difficulty in distinguishing between impairment and difference. While the literature suggests that standardized assessments are inappropriate for Indigenous Australian children, there is an absence of empirical documentation to show how Indigenous children perform on standardized tests of language ability. This study examined the performance of 19 Indigenous Australian children, aged 8;01-13;08, from one school on the Clinical Evaluation of Language Fundamentals, Fourth Edition, Australian Standardized Edition. Standardized scores were compared with teacher ratings of children's oral language skills. Analysis showed poor alignment between teacher ratings and language assessment, and assessment scores were negatively influenced by features of Aboriginal English. Children rated with above average language skills presented with different linguistic profiles from the children rated with average and below average language abilities. The inappropriateness of current standardized language assessments for Indigenous children and the need for further research to guide appropriate assessment are discussed.

    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.

    ABSTRACT This systematic review evaluated the epidemiology of community-acquired pneumonia in children <6 y of age within 90 developing and newly industrialized countries. Literature searches (1990–2011), based on MEDLINE, EMBASE, Cochrane, CAB Global Health, WHO, UNICEF, country-specific websites, conferences, health-technology-assessment agencies, and the reference lists of included studies, yielded 8,734 records; 62 of 340 studies were included in this review. The highest incidence rate among included studies was 0.51 episodes/child-year, for children <5 y of age in Bangladesh. The highest prevalence was in Chinese children <6 months of age (37.88%). The main bacterial pathogens were Streptococcus pneumoniae, Haemophilus influenzae and Mycoplasma pneumoniae and the main viral pathogens were respiratory syncytial virus, adenovirus and rhinovirus. Community-acquired pneumonia remains associated with high rates of morbidity and mortality. Improved and efficient surveillance and documentation of the epidemiology and burden of community-acquired pneumonia across various geographical regions is warranted. PMID:27269963

    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.

    AIM: To investigate the diagnostic accuracy of potent serum biochemical fibrosis markers in children with chronic hepatitis B evaluated by receiver operating characteristics (ROC) analysis.METHODS: We determined the serum level of apolipoprotein A-I (APO A-I), haptoglobin (HPT) and a-2macroglobulin (A2M) with an automatic nephelometer in 63 children (age range 4-17 years, mean 10 years)with biopsy-verified chronic HBeAg-positive hepatitis B.Fibrosis stage and inflammation grade were assessed in a blinded fashion according to Batts and Ludwig. We defined mild liver fibrosis as a score ≤2 and advanced fibrosis as a score equal to 3. ROC analysis was used to calculate the power of the assays to detect advanced liver fibrosis (AccuROC, Canada).RESULTS: Serum concentrations of APO A-I, HPT and A2M were not significantly different in patients with chronic hepatitis B compared to controls. However, APO A-I level of 1.19 ng/L had a sensitivity of 85.7% and a specificity of 60.7% (AUC = 0.7117, P = 0.035) to predict advanced fibrosis. All other serum biochemical markers and their combination did not allow a useful prediction.None of these markers was a good predictor of histologic inflammation.CONCLUSION: Apolipoprotein A-I may be a suitable serum marker to predict advanced liver fibrosis in children with chronic hepatitis B.

    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.

    Mycobacterium africanum comprises two phylogenetic lineages within the Mycobacterium tuberculosis complex (MTBC). M. africanum was first described and isolated in 1968 from the sputum of a Senegalese patient with pulmonary tuberculosis (TB) and it has been identified increasingly as an important cause of human TB, particularly prevalent in West Africa. The restricted geographical distribution of M. africanum, in contrast to the widespread global distribution of other species of MTBC, requires explanation. Available data indicate that M. africanum may also have important differences in transmission, pathogenesis, and host-pathogen interactions, which could affect the evaluation of new TB intervention tools (diagnostics and vaccines)-those currently in use and those under development. The unequal geographical distribution and spread of MTBC species means that individual research findings from one country or region cannot be generalized across the continent. Thus, generalizing data from previous and ongoing research studies on MTBC may be inaccurate and inappropriate. A major rethink is required regarding the design and structure of future clinical trials of new interventions. The West, Central, East, and Southern African EDCTP Networks of Excellence provide opportunities to take forward these pan-Africa studies. More investments into molecular, epidemiological, clinical, diagnostic, and immunological studies across the African continent are required to enable further understanding of host-M. africanum interactions, leading to the development of more specific diagnostics, biomarkers, host-directed therapies, and vaccines for TB.

    Despite the existence of a government-run tuberculosis (TB) control program, the current nationwide burden of TB continues to be a public health problem in Taiwan. Intense current and previous efforts into diagnostic, therapeutic, and preventive interventions have focused on TB in adults, but childhood TB has been relatively neglected. Children are particularly vulnerable to severe disease and death following infection, and children with latent infections become reservoirs for future transmission following disease reactivation in adulthood, thus fueling future epidemics. Additional research, understanding, and prevention of childhood TB are urgently needed. This review assesses the epidemiology, diagnosis, treatment, and relevant principles of TB vaccine development and presents efficacy data for the currently licensed vaccines.

    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%.

    Full Text Available Pediatric multiple trauma victims present a unique set of problems to the emergency physician, pediatrician, or surgeon. Children rarely sustain lethal injury; delayed recognition and inappropriate management of the common problems encountered in the pediatric trauma patient can lead to a poor outcome.This study was designed as a retrospective descriptive review of medical records of 289 injured children. All children were admitted in age from 1 to 15 years to the Republican Research Center of Emergency Medicine (Uzbekistan and its branches during 2000-2009.Caring for pediatric trauma patients requires an understanding of the distinct anatomy and pathophysiology of the pediatric population. Initial evaluation, management, and resuscitation require a multidisciplinary approach including trauma surgeons, anesthesiologists, and pediatric intensive care physicians.

    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). Overall diagnostic accuracy of MRI and pre

    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.

    Full Text Available Introduction. 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.

    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 National Institutes of Health and other federal agencies are considering initiating a cohort study of 500,000 people, including 120,000 children, to measure genetic and environmental influences on common diseases. A community engagement pilot study was conducted to identify public attitudes and concerns about the proposed cohort study, including the ethics of involving children. The pilot included 15 focus groups where the inclusion of children in the proposed cohort study was discussed. Focus groups, conducted in six cities, included 141 adults of different ages, incomes, genders, ethnicities, and races. Many of the concerns expressed by participants mirrored those addressed in pediatric research guidelines. These concerns included minimizing children's fear, pain, and burdens; whether to include young children; and how to obtain children's assent. There was little agreement about which children can assent. Some voiced concern about children's privacy, but most expected that parents would have access to children's study results. Some believed children would not benefit from participating, while others identified personal and societal benefits that might accrue. A few people believed that children's participation would not advance the study's goals. To successfully include children, proposed cohort study would need to address children's changing capabilities and rights as they grow and reach the age of consent.

    Examined the performance of 64 children on the Minnesota Percepto-Diagnostic test (MPD) who were diagnosed as either Brain-Damaged (BD) or emotionally impaired Non-Brain-Damaged (NBD). There were 31 children in the NBD group and 33 in the BD group. The MPD T-score and Actuarial Table significantly differentiated between the two groups. Seventy-four percent of the combined BD-NBD groups were identified correctly. Additional discriminant analysis on this sample yielded combined BD-NBD groups classification rates that ranged from 77% with the MPD variables Separation of Circle-Diamond (SPCD), Distortion of Circle-Diamond (DCD) and Distortion of Dots (DD) to 83% with the WISC-R three IQ scores plus the MPD T-score, SPCD and DD. The MPD T-score and Actuarial Table (MPD Two-Step Diagnosis) appeared to generalize to other populations more readily than discriminant analysis formulae, which tend to be sensitive to the samples from which they are derived.

  14. Ventilator-associated pneumonias in children (I)--diagnostic criteria, etiology and pathogenesis.

    Yankov, Ivan V; Shmilev, Tonyo I

    2012-01-01

    Ventilator-associated pneumonias have been estimated to be the second most common nosocomial infections among children treated in intensive care units. They occur in mechanically ventilated patients through intubation tube or tracheostomy, the inflammation usually involving the lung parenchyma. The ventilator-associated pneumonia is associated with a longer antibiotic treatment, greater duration of mechanical ventilation (MV) and higher mortality rates in children. The condition is also associated with a higher cost of the treatment. This paper reviews and comments in detail the criteria formulated by the National Nosocomial Infection Surveillance (NNSI) and the Centers for Disease Control and Prevention (CDC) for diagnosis of ventilator-associated pneumonias in children. The disease etiology is associated with the typical causes of nosocomial infections in this age: P. aeruginosa, E. coli and K. pneumoniae. The pathogenesis of the condition is inadequately studied but the aspiration of gastric contents and immune deficiency are proven risk factors. Two mechanisms have a major role in the development of the disease--micro-aspiration of gastric contents and colonization of the lower airways with pathogens.

    This study reports the epidemiology of respiratory syncytial virus (RSV) in hospitalized children in Cyprus over three successive seasons (2010-2013) and the association between prevalent genotypes and disease severity. RSV infections had a circulation pattern from December to March. Most RSV-positive children (83%) were aged <2 years. Genotyping of RSV isolates showed that during the first winter season of the study (2010-2011), the only RSV genotype circulating was GA2 (RSV-A), followed by genotype BA (RSV-B) in the next winter season with only few sporadic cases of GA2. During the last winter season of the study (2012-2013) the newly emerged RSV genotype ON1 (RSV-A) was virtually the only circulating genotype. Children infected with genotype ON1 suffered a significantly milder illness compared to infections with genotypes GA2 and BA with a higher percentage of BA-infected children requiring oxygen. Our findings are in contrast to the majority of published reports that suggest RSV-A causes more severe illness than RSV-B. Therefore, further investigation of the association between RSV genotypes and disease severity is required, as it might affect treatment strategies in the future.

    The goal of the study was twofold: (1) to investigate the effect of different diagnostic criteria on prevalence estimates of adult attention deficit hyperactivity disorder (ADHD), and (2) to provide prevalence estimates of adult ADHD for the first time in a Hungarian sample. Subjects between 18 and 60 years were included in the screening phase of the study (N = 3,529), conducted in 17 GP practices in Budapest. Adult self-report scale 6-item version was used for screening. Out of 279 positively screened subjects 161 subjects participated in a clinical interview and filled out a self-report questionnaire to confirm the diagnosis. Beside DSM-IV diagnostic criteria, we applied four alternative diagnostic criteria: 'No-onset' (DSM-IV criteria without the specific requirement for onset); full/Sx (DSM-IV "symptoms only" criteria); and reduced/Sx (DSM-IV "symptoms only" criteria with a reduced threshold for symptom count). Crude prevalence estimates adjusted for the specificity and sensitivity data of the screener were 1.35% in the 'DSM-IV' group, 1.64% in the 'No-onset' group, 3.65% in the 'Sx/full' group and 4.16% in the 'Sx/reduced' group. Logistic regression analysis showed that ADHD was significantly more prevalent with younger age and male gender [chi(2) = 14.46; P = 0.0007]. Prevalence estimates corrected for the 'not-interviewed' subsample and adjusted for specificity and sensitivity data of the screener was 2.3% in males, 0.91% in females; 2.02% in the 40 years age group, based on DSM-IV diagnostic criteria. Prevalence rates found in this study are somewhat lower, but still are in line with those reported in the literature.

    A clinical evaluation of hydro-MRI as an alternative method to barium studies in children with abdominal pain of unknown origin is presented. Patients and Methods: 20 children with abdominal pain of unknown origin aged from 9 - 16 years were examined after oral bowel opacification using 1000 ml of 2.5% mannitol solution with a 1.0T MRI system. The investigation was done in 2 planes (coronal and axial) under breath-hold conditions. Imaging procedures included various sequences (T2W HASTE + FS, contrast-enhanced T1W FLASH FS). Suspicious findings in bowel segments and extra-intestinal changes were assessed. Results: In 21/24 examinations the small bowel was completely visualized, in 15/24 cases colon segments were identified. An accurate assessment of the terminal ileum was not possible in 3/24 procedures. Breathing artefacts occurred in 3/24 examinations. Signs of Crohn's disease were found in 4 examinations, inflammatory changes of the ileum were detected in 3 cases. Inflammation of the colon was demonstrated in 2 children. Furthermore, pathological findings included constipation in one child and inflammation of the ileo-colic and mesenterial lymph nodes were found in another child. Extra-intestinal changes in 3 children were caused by ovarian cysts, and in one case by pleural effusion. In 4 examinations we detected ascites in the absence of other pathological findings. In 5 children there was no pathological correlation in the bowel or extra-intestinal region for the complaints. The children tolerated the hydro-MRI very well. There were no side effects using oral mannitol. (orig.)

    Full Text Available Examination of the anatomical and functional states of feet in children with congenital clubfoot is an urgent priority that has significant theoretical and practical value. The purpose of the study was to investigate the morphological and functional parameters of the foot to evaluate the degree of affection of its support function in congenital clubfoot using the technique of computer plantography. Plantographic characteristics of the feet were determined in 65 children with this disorder, aged from 4 to 16 years. The mathematical processing of plantographic characteristics of the feet was performed using the following; the calcaneo-axial and the calcaneo-metatarsal angles and the angle between the outer tangents on the basis of what were defined border values of angles, depending on the severity of foot deformities. The proposed method of analysis of the foot plantogram is statistically significant for the classification of congenital clubfoot with different degrees of severity: mild, moderate, and severe. This technique is an addition to the clinical and X-ray methods and allows the evaluation of functional support for the feet.

    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. We will

    Chronic tics (CT) are observed in 3-4% population, Tourette syndrome (TS) in 0.1-3.0%. In most cases, tic disorders start at age 2-15 years, but frequently they are diagnosed late. Clinical presentations of tics and comorbid disorders are various and depend on child's age. Difficulties in treatment of CT are associated with their persistence and those for TS with the fluctuating course of tics and probable onset of the disease in the form of behavioral disorders. Treatment of CT and TS is individual. Methods of behavioral and psychotherapy are recommended for a certain period of time if tics do not hamper everyday life. Increase in tick frequency and severity indicate the necessity of using pharmacological treatment. The European recommendations on pharmacotherapy of tic disorders and the drugs available in Russia are considered. Results of the studies on the efficacy of antiepileptic drugs and tenoten children in CT and TS are presented.

    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.

    Full Text Available BACKGROUND: Clinical significance of Staphylococcus aureus colonization has been demonstrated in hospital settings; however, studies in the community have shown contrasting results regarding the relevance of colonization in infection by community-associated MRSA (CA-MRSA. In Colombia there are few studies on S. aureus colonization. The aim of this study was to determine the molecular and epidemiological characteristics of nasal colonization by S. aureus (MSSA-MRSA in children from a university hospital and day care centers (DCCs of Medellin, Colombia. METHODS: An observational cross-sectional study was conducted in 400 children (200 in each setting, aged 0 months to 5 years, during 2011. Samples were collected from each nostril and epidemiological information was obtained from the parents. Genotypic analysis included spa typing, PFGE, MLST, SCCmec typing, detection of genes for virulence factors and agr groups. RESULTS: Frequency of S. aureus colonization was 39.8% (n = 159 (hospital 44.5% and DCCs 35.0% and by MRSA, 5.3% (n = 21 (hospital 7.0% and DCCs 3.5%. Most S. aureus colonized children were older than two years (p = 0.005, the majority of them boys (59.1%, shared a bedroom with a large number of people (p = 0.028, with history of β-Lactamase inhibitors usage (p = 0.020. MSSA strains presented the greatest genotypic diversity with 15 clonal complexes (CC. MRSA isolates presented 6 CC, most of them (47.6% belonged to CC8-SCCmec IVc and were genetically related to previously reported infectious MRSA strains. CONCLUSION: Differences in epidemiological and molecular characteristics between populations may be useful for the understanding of S. aureus nasal colonization dynamics and for the design of strategies to prevent S. aureus infection and dissemination. The finding of colonizing MRSA with similar molecular characteristics of those causing infection demonstrates the dissemination capacity of S. aureus and the risk of

    Fever of unknown origin (FUO) and unexplained signs of inflammation are challenging medical problems especially in children and predominantly caused by infections, malignancies or noninfectious inflammatory diseases. The aim of this study was to assess the diagnostic value of {sup 18}F-FDG PET and PET/CT in the diagnostic work-up in paediatric patients. In this retrospective study, 47 FDG PET and 30 PET/CT scans from 69 children (median age 8.1 years, range 0.2-18.1 years, 36 male, 33 female) were analysed. The diagnostic value of PET investigations in paediatric patients presenting with FUO (44 scans) or unexplained signs of inflammation without fever (33 scans) was analysed. A diagnosis in paediatric patients with FUO or unexplained signs of inflammation could be established in 32 patients (54%). Of all scans, 63 (82%) were abnormal, and of the total number of 77 PET and PET/CT scans 35 (45%) were clinically helpful. In patients with a final diagnosis, scans were found to have contributed to the diagnosis in 73%. Laboratory, demographic or clinical parameters of the children did not predict the usefulness of FDG PET scans. This is the first larger study demonstrating that FDG PET and PET/CT may be valuable diagnostic tools for the evaluation of children with FUO and unexplained signs of inflammation. Depicting inflammation in the whole body, while not being traumatic, it is attractive for use especially in children. The combination of PET with CT seems to be superior, since the site of inflammation can be localized more accurately. (orig.)

    UTI in young infants generally presents with fever. Among the youngest infants, boys and girls are equally affected. The incidence of UTI in uncircumcised boys is comparable with that in girls, whereas the rate in circumcised boys is much lower. Based on gender and race, white girls have the highest incidence of UTI. A full understanding of the epidemiology of UTI is complicated by the presence of asymptomatic bacteriuria and by incomplete evidence regarding the significance of scarring and the risk of sequelae.

  11. Serum IgA responses against pertussis proteins in infected and Dutch wP or aP vaccinated children: an additional role in pertussis diagnostics.

    Lotte H Hendrikx

    Full Text Available BACKGROUND: Whooping cough is a respiratory disease caused by Bordetella pertussis, which induces mucosal IgA antibodies that appear to be relevant in protection. Serum IgA responses are measured after pertussis infection and might provide an additional role in pertussis diagnostics. However, the possible interfering role for pertussis vaccinations in the induction of serum IgA antibodies is largely unknown. METHODS/PRINCIPAL FINDINGS: We compared serum IgA responses in healthy vaccinated children between 1 and 10 years of age with those in children who despite vaccinations recently were infected with Bordetella pertussis. All children have been vaccinated at 2, 3, 4 and 11 months of age with either the Dutch whole-cell pertussis (wP vaccine or an acellular pertussis (aP vaccine and additionally received an aP booster vaccination at 4 years of age. Serum IgA responses to pertussis toxin (PT, filamentous heamagglutinin (FHA and pertactin (Prn were measured with a fluorescent multiplex bead-based immuno-assay. An ELISPOT-assay was used for the detection of IgA-memory B-cells specific to these antigens. Serum IgA levels to all pertussis vaccine antigens were significantly higher in infected children compared with healthy children. High correlations between anti-PT, anti-FHA or anti-Prn IgA and IgG levels were found in infected children and to some degree in wP primed children, but not at all in aP primed children. Highest numbers of IgA-pertussis-specific memory B-cells were observed after infection and generally comparable numbers were found after wP and aP vaccination. CONCLUSIONS: This study provides new insight in the diagnostic role for serum IgA responses against PT in vaccinated children. Since aP vaccines induce high serum IgG levels that interfere with pertussis diagnostics, serum IgA-PT levels will provide an additional diagnostic role. High levels of serum IgA for PT proved specific for recent pertussis infection with reasonable

    Full Text Available Abstract Background Diligent and correct laboratory diagnosis and up-front identification of risk factors for progression to severe disease are the basis for optimal management of malaria. Methods Febrile children presenting to the Medical Research Unit at the Albert Schweitzer Hospital (HAS in Lambaréné, Gabon, were assessed for malaria. Giemsa-stained thick films for qualitative and quantitative diagnosis and enumeration of malaria pigment, or haemozoin (Hz-containing leukocytes (PCL were performed, and full blood counts (FBC were generated with a Cell Dyn 3000® instrument. Results Compared to standard light microscopy of Giemsa-stained thick films, diagnosis by platelet count only, by malaria pigment-containing monocytes (PCM only, or by pigment-containing granulocytes (PCN only yielded sensitivities/specificities of 92%/93%; 96%/96%; and 85%/96%, respectively. The platelet count was significantly lower in children with malaria compared to those without (p ® instrument detected significantly more patients with PCL (p Conclusion In the age group examined in the Lambaréné area, platelets are an excellent adjuvant tool to diagnose malaria. Pigment-containing leukocytes (PCL are more readily detected by automated scatter flow cytometry than by microscopy. Automated Hz detection by an instrument as used here is a reliable diagnostic tool and correlates with disease severity. However, clinical usefulness as a prognostic tool is limited due to an overlap of PCL numbers recorded in severe versus non-severe malaria. However, this is possibly because of the instrument detection algorithm was not geared towards this task, and data lost during processing; and thus adjusting the instrument's algorithm may allow to establish a meaningful cut-off value.

    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 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.

    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

    Frank Baiden

    Full Text Available INTRODUCTION: WHO now recommends test-based management of malaria (TBMM across all age-groups. This implies artemisinin-based combination treatment (ACT should be restricted to rapid diagnostic test (RDT-positive cases. This is a departure from what caregivers in rural communities have been used to for many years. METHODS: We conducted a survey among caregivers living close to 32 health centres in six districts in rural Ghana and used logistic regression to explore factors likely to influence caregiver acceptability of RDT based case management and concern about the denial of ACT on account of negative RDT results. Focus group discussions were conducted to explain the quantitative findings and to elicit further factors. RESULTS: A total of 3047 caregivers were interviewed. Nearly all (98% reported a preference for TBMM over presumptive treatment. Caregivers who preferred TBMM were less likely to be concerned about the denial of ACT to their test-negative children (O.R. 0.57, 95%C.I. 0.33-0.98. Compared with caregivers who had never secured national health insurance cover, caregivers who had valid (adjusted O.R. 1.30, 95% CI 1.07-1.61 or expired (adjusted O.R. 1.38, 95% CI 1.12-1.73 insurance cover were more likely to be concerned about the denial of ACT to their RDT-negative children. Major factors that promote TBMM acceptability include the perception that a blood test at health centre level represents improvement in the quality of care, leads to improvement in treatment outcomes, and offers opportunity for better communication between health workers and caregivers. Acceptability is also enhanced by engaging caregivers in the procedures of the test. Apprehensions about negative health worker attitude could however undermine acceptance. CONCLUSION: Test (RDT-based management of malaria in under-five children is likely to be acceptable to caregivers in rural Ghana. The quality of caregiver-health worker interaction needs to be improved if

    The aim of the study was assessment of the usefulness of multiplex real-time PCR tests in the diagnostic and therapeutic process in children hospitalized due to pneumonia and burdened with comorbidities. Methods. The study group included 97 children hospitalized due to pneumonia at the Karol Jonscher Teaching Hospital in Poznań, in whom multiplex real-time PCR tests (FTD respiratory pathogens 33; fast-track diagnostics) were used. Results. Positive test results of the test were achieved in 74 patients (76.3%). The average age in the group was 56 months. Viruses were detected in 61 samples (82% of all positive results); bacterial factors were found in 29 samples (39% of all positive results). The presence of comorbidities was established in 90 children (92.78%). On the basis of the obtained results, 5 groups of patients were established: viral etiology of infection, 34 patients; bacterial etiology, 7 patients; mixed etiology, 23 patients; pneumocystis, 9 patients; and no etiology diagnosed, 24 patients. Conclusions. Our analysis demonstrated that the participation of viruses in causing severe lung infections is significant in children with comorbidities. Multiplex real-time PCR tests proved to be more useful in establishing the etiology of pneumonia in hospitalized children than the traditional microbiological examinations.

Results. Positive test results of the test were achieved in 74 patients (76.3%). The average age in the group was 56 months. Viruses were detected in 61 samples (82% of all positive results); bacterial factors were found in 29 samples (39% of all positive results). The presence of comorbidities was established in 90 children (92.78%). On the basis of the obtained results, 5 groups of patients were established: viral etiology of infection, 34 patients; bacterial etiology, 7 patients; mixed etiology, 23 patients; pneumocystis, 9 patients; and no etiology diagnosed, 24 patients. Conclusions. Our analysis demonstrated that the participation of viruses in causing severe lung infections is significant in children with comorbidities. Multiplex real-time PCR tests proved to be more useful in establishing the etiology of pneumonia in hospitalized children than the traditional microbiological examinations. PMID:28182108

    The purpose of this study was to evaluate the psychometric properties of DSM-IV symptom criteria for assessing personality disorders (PDs) in a national population and to compare variations in proposed symptom coding for social and/or occupational dysfunction. Data were obtained from a total sample of 34,653 respondents from Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). For each personality disorder, confirmatory factor analysis (CFA) established a 1-factor latent factor structure for the respective symptom criteria. A 2-parameter item response theory (IRT) model was applied to the symptom criteria for each PD to assess the probabilities of symptom item endorsements across different values of the underlying trait (latent factor). Findings were compared with a separate IRT model using an alternative coding of symptom criteria that requires distress/impairment to be related to each criterion. The CFAs yielded a good fit for a single underlying latent dimension for each PD. Findings from the IRT indicated that DSM-IV PD symptom criteria are clustered in the moderate to severe range of the underlying latent dimension for each PD and are peaked, indicating high measurement precision only within a narrow range of the underlying trait and lower measurement precision at lower and higher levels of severity. Compared with the NESARC symptom coding, the IRT results for the alternative symptom coding are shifted toward the more severe range of the latent trait but generally have lower measurement precision for each PD. The IRT findings provide support for a reliable assessment of each PD for both NESARC and alternative coding for distress/impairment. The use of symptom dysfunction for each criterion, however, raises a number of issues and implications for the DSM-5 revision currently proposed for Axis II disorders (American Psychiatric Association, 2010).

    BACKGROUND: Epidemiological research is facilitated in Sweden by a history of national health care registers, making large unselected national cohort studies possible. However, for complex clinical populations, such as children with congenital heart disease (CHD), register-based studies...... are challenged by registration limitations. For example, the diagnostic code system International Classification of Diseases, 10th version (ICD-10) does not indicate the clinical significance of abnormalities, therefore may be of limited use if used as the sole parameter in epidemiological research.

    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.

    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.

    Full Text Available India, a developing country, faces many challenges in rendering oral health needs. The majority of Indian population resides in rural areas of which more than 40% constitute children. The purpose of this study was to assess the oral health status of 5 years and 12 years school going children in Chennai city. The study population consisted of 1200 school children of both the sexes (600 private and 600 corporation school children in 30 schools, which had been selected randomly. The survey is based on WHO, 1999 Oral Health Assessment, which has been modified by including gingival assessment, enamel opacities/ hypoplasia for 5 years. Evaluation of the oral health status of these children revealed, dental caries is the most prevalent disease affecting permanent teeth, more than primary teeth and more in corporation than in private schools, thereby, correlating with the socioeconomic status. It may be concluded that the greatest need of dental health education is at an early age including proper instruction of oral hygiene practices and school based preventive programs, which would help in improving preventive dental behaviour and attitude which is beneficial for life time.

    2014-12-05

    Epigenetic epidemiology includes the study of variation in epigenetic traits and the risk of disease in populations. Its application to the field of cancer has provided insight into how lifestyle and environmental factors influence the epigenome and how epigenetic events may be involved in carcinogenesis. Furthermore, it has the potential to bring benefit to patients through the identification of diagnostic markers that enable the early detection of disease and prognostic markers that can inform upon appropriate treatment strategies. However, there are a number of challenges associated with the conduct of such studies, and with the identification of biomarkers that can be applied to the clinical setting. In this review, we delineate the challenges faced in the design of epigenetic epidemiology studies in cancer, including the suitability of blood as a surrogate tissue and the capture of genome-wide DNA methylation. We describe how epigenetic epidemiology has brought insight into risk factors associated with lung, breast, colorectal and bladder cancer and review relevant research. We discuss recent findings on the identification of epigenetic diagnostic and prognostic biomarkers for these cancers.

    Full Text Available Purpose: The most common chronic disease of childhood is early childhood caries which is five times more prevalent than asthma and seven times higher than that of allergic rhinitis. Most children do not receive dental care until they are three years old, yet by the time more than thirty percent of children from lower socioeconomic groups already have caries. To determine the prevalence and severity of early childhood caries among pre-school children, to describe the child characteristics associated with the development of early childhood caries and to find the association of early childhood caries and maternal risk factors. Materials and Methods: This descriptive study was carried out among children attending the immunization clinic of Sree Avittam Thirunal Hospital, Medical College, Trivandrum and children attending the randomly selected Anganwadies and Day care centres in Trivandrum, the capital of Kerala, wherein there are migrants from all over the State.

    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. CONCLUSIONS: Only a small proportion of children

    2016-11-01

    Brain tumors are the commonest solid tumor in children, leading to significant cancer-related mortality. Several hereditary syndromes associated with brain tumors are nonfamilial. Ionizing radiation is a well-recognized risk factor for brain tumors. Several industrial exposures have been evaluated for a causal association with brain tumor formation but the results are inconclusive. A casual association between the common mutagens of tobacco, alcohol, or dietary factors has not yet been established. There is no clear evidence that the incidence of brain tumors has changed over time. This article presents the descriptive epidemiology of the commonest brain tumors of children and adults.

    Full Text Available The safety of children younger than 10 years on motorized two-wheeled vehicles (MTWs in low- and middle-income countries receives substantial attention from global road safety advocates. However, there is little empirical evidence available to describe the magnitude of the problem. Therefore, we constructed a population-level database of road traffic injury statistics disaggregated by age (<5, 5–9, 10+ years and mode of transport. Our database included mortality data from 44 countries and 5 Indian cities, and hospital admissions from 17 countries. The MTW fleet in these settings ranged from 2% to 70% of all registered vehicles. We find that children under 5 years averaged 0.05% (SD 0.13% of all road traffic deaths, and 5–9 year olds averaged 0.11% (SD 0.25%. Even in regions with high prevalence of MTWs, young children comprised at most 1.5% of all road traffic deaths and 5.8% of all MTW deaths. Young children were a slightly larger proportion of all road traffic deaths in countries where MTWs were more common. However, after adjusting for population age structure, this effect was no longer evident. The percentage of child road traffic injuries that are due to MTWs increased with increasing MTW use, but at a much lower rate. Our findings suggest that children may be at lower risk from MTW crashes than previously assumed, and certainly at a lower risk than as pedestrians. Further studies are needed to explain the underlying mechanisms that regulate risk of road users.

    2014-01-01

    Juvenile idiopathic arthritis (JIA) is a group of disorders characterized by arthritis persisting for at least 6 weeks with onset before the age of 16 years. Within this cluster of conditions, the polyarticular form (involving more than four joints within the first 6 months) is further divided based on the presence of rheumatoid factor. Children with polyarticular JIA pose unique diagnostic and therapeutic challenges compared to children with involvement of fewer joints. Polyarticular JIA patients tend to have a more refractory course and therefore are at increased risk for joint damage, resulting in poorer functional outcomes and decreased quality of life. Although the ability to treat this disorder continues to improve, especially with the advent of biologic agents, there is still much about the epidemiology and pathogenesis of polyarticular JIA that is unknown. The epidemiology of polyarticular JIA varies worldwide with a vast difference in reported cases between different global regions as well as within individual countries. Several genetic risk loci have been identified conferring increased susceptibility to JIA, many within the human leukocyte antigen region. Beyond the genome, environmental factors also seem to contribute to the etiology of polyarticular JIA. This review article will focus on the epidemiology and current treatments of polyarticular JIA and briefly discuss genetic and environmental influences on the pathogenesis of JIA as well as new and emerging therapies.

Cost-effective and sensitive rapid diagnostic tests have been recently proposed as alternatives to microscopy. In Equatorial Guinea, a study was conducted to assess the reliability of a rapid diagnostic test compared to microscopy. The study was designed in accordance with the directives of the Standards for Reporting Diagnostic Accuracy Initiative (STARD. Peripheral thick and thin films for the microscopy diagnosis and a rapid immunochromatographic test (ICT Malaria Combo Cassette Test were performed on under five-year-old children with malaria suspicion. The ICT test detected Plasmodium spp. infection with a sensitivity of 81.5% and a specificity of 81.9% while P. falciparum diagnosis occurred with a sensitivity of 69.7% and a specificity of 73.7%. The sensitivity of the ICT test increased with higher parasitemias. The general results showed little concordance between the ICT test and microscopy (kappa = 0.28, se: 0.04. In Equatorial Guinea, the ICT Malaria Combo Cassette Test has proven to be an acceptable test to detect high P. falciparum parasitemias. However, the decrease of sensitivity at medium and low parasitemias hampers that ICT can replace properly performed microscopy at present in the diagnosis of malaria in children.

    Full Text Available Abstract Background Instruments for field diagnosis of eczema are increasingly used, and it is essential to understand specific limitations to make best use of their strengths. Our objective was to assess the validity of ISAAC and UK Working Party criteria for field diagnosis of eczema in children. Methods We performed a cohort study in urban Brazil. Parents/guardians of 1,419 children answered ISAAC phase II questionnaire. Children were examined for skin lesions (UKWP protocol. Two dermatologists examined most cases of eczema (according to ISAAC or UKWP, and a sample without eczema. Results Agreement between repeat questionnaires on the filter question was poor (kappa = 0.4. Agreement between the 2 dermatologists was fair (kappa = 0.6. False positive reports included scabies in 39% of ISAAC cases and 33% of UKWP cases. Sensitivity and PPV were low (ISAAC: 37.1% and 16.1%; UKWP: 28.6% and 23.8%. Specificity and NPV were high (ISAAC: 90.0% and 96.6%; UKWP: 95.3% and 96.2%. One-year prevalence of eczema was 11.3% (ISAAC, 5.9% (UKWP and 4.9% (adjusted dermatologist diagnosis. Point prevalence of scabies (alone or not was 43%, 33% and 18%, in eczemas according to ISAAC, to UKWP and to dermatologists. The reasons why children with eczema were not identified by ISAAC or UKWP were wrongly denying dry skin, itchy rash or personal history of atopic diseases. A limitation is that questionnaire was already validated in Brazil, but not field tested in this specific setting. Conclusions Studies using UKWP or ISAAC criteria should include a validation arm, to contribute to the understanding of potential limitations of their use in different contexts and to explore solutions. We list specific recommendations.

    In April 1994, Vibrio metschnikovii was isolated from five infants with watery diarrhoea in Arequipa, Peru, as part of a passive cholera surveillance system. The children ranged in age from 11 to 20 months and had acute diarrhoea, with two cases showing moderate dehydration. Two children also had traces of blood in liquid stool. The children were seen at two different hospitals, and no evidence of a common source of infection was found. No additional V. metschnikovii isolates were identified in the remaining surveillance period that covered the rest of 1994 and 1995. However, stool samples were not screened for enteric pathogens other than vibrios. V. metschnikovii strains isolated from stool samples produced opaque and translucent colonies on agar plates, suggesting capsular material. All isolates were resistant to ampicillin, erythromycin and streptomycin. Plasmid analysis revealed a common 200-kb plasmid in isolates from all cases and an additional 2.7-kb plasmid in three of the isolates. Ribotyping of each isolate after restriction with BglI and HindIII endonucleases demonstrated identical ribotyping patterns. The cases reported suggest that V. metschnikovii may be associated with diarrhoea in man by mechanisms so far unknown.

    Full Text Available Abstract Background The metabolic syndrome has been described in children; however, a standard criterion has not been established for its diagnosis. Also, few studies have been conducted to specifically observe the possible existence of agreement among the existing diagnostic criteria. The purpose of the study is to evaluate agreement concerning prevalence rates of the metabolic syndrome diagnosed by six different criteria in overweight schoolchildren in the city of Botucatu - SP -Brazil. Methods This is a cross-sectional study on 128 overweight schoolchildren. Clinical examination included anthropometry, pubertal staging evaluation, and blood pressure. Triacylglycerol, glycemia, HDL-cholesterol, insulin levels, and HOMA-IR were determined. The Kappa index, the Mann-Whitney test and the chi-square test were used for statistical analysis. Results The prevalence of the metabolic syndrome varied from 10 to 16.5% according to different diagnostic criteria. Results were similar for boys and girls and pubertal stage. Great agreement was observed among the six different diagnostic criteria for the metabolic syndrome. Conclusions Different diagnostic criteria, when adopted for subjects with similar demographic characteristics, generate similar and compatible prevalence. Results suggest that it is possible to adopt any of the analyzed criteria, and the choice should be according to the components available for each situation.

    The incidence and characteristics of AIH differ in various geographic regions. Based on limited epidemiologic studies, the incidence of type 1 AIH among Caucasoid populations of Europe and North America ranges from 0.1 to 1.9/100,000/year. The disease is considerably less frequent in Japan. The relative proportion of AIH among cases with chronic hepatitis is low in regions with a high prevalence of viral hepatitis. Type 2 AIH is more frequent in southern Europe than in northern Europe, the United States, and Japan. The occurrence of anti-SLA/LP is also higher in European than in Japanese patients with type 1 AIH. The frequency of HLA markers that affect susceptibility to AIH varies between ethnic groups. DRB1*0301 (DR3) and DRB1*0401 (DR4) are the major risk factors for type 1 AIH in white European and North American populations. DRB1*0405 (DR4) is the principal risk factor in Japanese and adult Argentine patients with type 1 AIH, and DRB1*0404 (DR4) is the main susceptibility allele in Mestizo Mexicans. Children may have different clinical manifestations than adults, and the diagnoses of type 2 AIH, autoimmune sclerosing cholangitis, and APS1 should be considered. Uniform application of diagnostic criteria formulated by the International Autoimmune Hepatitis Group should strengthen future epidemiologic studies and extend awareness of AIH to yet unstudied minority groups.

    In order to obtain reliable information about time-domain ECG parameters in Russian children and to analyse their links with physiological changes the Project "ECG screening of children and adolescents of the Russian Federation" was carried out in 2003-2008. Time domain ECG parameters were studied in the representative sample of 5387 healthy individuals aged 0 to 18 years. In each age group, lower and upper limits of the norm for heart rate (HR), P wave, PQ and QRS intervals were defined as 2nd and 98th percentiles of their distribution. The equivalent limits of QT interval duration were defined as its 5th and 95th percentiles. Relationship between time domain parameters of pediatric ECG and HR was analyzed as well as relationship of these parameters with sex and age. The most important differences from prior pediatric studies completed 30 years ago were obtained for the heart rate limits. Among children aged 0 to 3, there was a tendency toward lowering of age-specific lower limits and elevation of age-specific upper limits. At ages older than 3 years, there was a tendency toward lowering of both the upper and the lower limits of HR. The newly obtained 2nd percentiles of the heart rate were lower than the known lower limits in nearly all ages. This indicates the necessity for revision of criteria of bradicardia in children. The present study showed that 5th and 95th percentiles of QTc interval (Bazett's formula) varied between 340 ms and 465 ms and were not significantly dependent on children's age and only for ages under 13 also on sex. Results of the study allowed to build age-specific ranges of norm for the time domain ECG parameters presented in a tabular form.

    Full Text Available OBJECTIVE: To describe the epidemiological characteristics of infantile hypertrophic pyloric stenosis (IHPS in ethnic Chinese children. MATERIALS AND METHODS: We reviewed the National Health Insurance claims database and analyzed data from children less than one year of age who had been diagnosed with IHPS (ICD-9-CM 750.5 and had undergone pyloromyotomy (ICD-9-CM 43.3. We analyzed the incidence, gender, age at diagnosis, length of hospital stay, seasonal variation and cost of IHPS from data collected between January 1997 and December 2007. RESULTS: A total of 1,077 infants met inclusion criteria, including 889 boys and 188 girls. The annual incidence of IHPS ranged from 0.30 to 0.47 per 1,000 live births with a mean incidence of 0.39 per 1,000 live births. Between 2002 and 2007, the incidence showed a declining trend (P = 0.025 with coincidentally increasing trends for both exclusive breastfeeding (P = 0.014 and breastfeeding plus bottle feeding (P = 0.004. The male-to-female rate ratio was dynamic and increased from 3.03 during the first two weeks of life to 8.94 during the 8(th through 10th weeks of life. The overall male-to-female rate ratio was 4.30. The mean age at diagnosis was 43.1 ± 2.4 days. After analyzing the months of birth and hospital admission, no seasonal variation associated with IHPS was detected. The mean length of hospital stay was 8.28 ± 7.10 days. CONCLUSIONS: The incidence of IHPS in Taiwan, a country with a majority ethnic Chinese population, was lower than observed incidences in Caucasian populations living in Western countries. Breastfeeding campaigns and low maternal smoking rates may contribute to the lower incidence of IHPS in Taiwan. However, additional studies with longer follow-up periods are needed.

    Full Text Available 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 < .001. The rate of coronary 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.

    Introduction Accurate etiological diagnosis of meningitis is important, but difficult in resource-limited settings due to prior administration of antibiotics and lack of viral diagnostics. We aimed to develop and validate 2 real-time multiplex PCR (RT-PCR) assays for the detection of common causes of community-acquired bacterial and viral meningitis in South African children. Methods We developed 2 multiplex RT- PCRs for detection of S. pneumoniae, N. meningitidis, H. influenzae, enteroviruses, mumps virus and herpes simplex virus. We tested residual CSF samples from children presenting to a local paediatric hospital over a one-year period, whose CSF showed an abnormal cell count. Results were compared with routine diagnostic tests and the final discharge diagnosis. We calculated accuracy of the bacterial RT-PCR assay compared to CSF culture and using World Health Organisation definitions of laboratory-confirmed bacterial meningitis. Results From 292 samples, bacterial DNA was detected in 12 (4.1%) and viral nucleic acids in 94 (32%). Compared to CSF culture, the sensitivity and specificity of the bacterial RT-PCR was 100% and 97.2% with complete agreement in organism identification. None of the cases positive by viral RT-PCR had a bacterial cause confirmed on CSF culture. Only 9/90 (10%) of patients diagnosed clinically as bacterial meningitis or partially treated bacterial meningitis tested positive with the bacterial RT-PCR. Discussion In this population the use of 2 multiplex RT-PCRs targeting 6 common pathogens gave promising results. If introduced into routine diagnostic testing, these multiplex RT-PCR assays would supplement other diagnostic tests, and have the potential to limit unnecessary antibiotic therapy and hospitalisation.

    In the region Eindhoven 36 children with Campylobacter-enteritis were examined from I January 1980 to 31 December 1980. Symptoms were studied and stools were cultured over a four-month period. Abdominal pain and/or diarrhea occurred in more than 90% of patients and were not infrequently of longer duration. Bloody stools were found in 58% of patients and disappeared relatively early during the time of illness, as well as fever and vomiting. After one month Campylobacter could only be cultured in 5% of children; 14 household contacts, who proved to have Campylobacter-enteritis, had also negative stool cultures after one month. Asymptomatic carriership was found in four cases among these household contracts. Campylobacter fetus subspecies jejuni could not be isolated in stools of a number of asymptomatic individuals, working in the meat industry, who were considered to have a higher risk of infection. This group could therefore not be determined as an endogenous human reservoir. On the other hand Campylobacter was isolated in a few domestic animals without symptoms of illness, as well as in some cattle stables and sites. In these places, where several contaminated animals are together, significant reservoirs for human infection may be present.

    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

    As there are some difficulties in the performance of renal biopsy and intravenous pyelography is of little use in children with chronic renal insufficiency, we evaluated the usefulness of sup(99m)Tc-DTPA renogram in two children. The causes of the renal insufficiency presented were obstructive congenital anomalies and chronic pyelonephritis in one patient and polycystic kidneys in the other. As expected, intravenous pyelography poorly visualized in the upper urinary tracts of both the cases examined. Sup(99m)Tc-DTPA renogram gave us distinct image for the diagnosis of the kidneys and urinary tracts, and the individual renal functions were clarified as well. It was apparently superior to the combined use of sup(99m)Tc-DMSA renoscintigram and /sup 131/I-Hippuran renogram in both the imaging and functional evaluations. In such cases as are reported herein, sup(99m)Tc-DTPA renogram might be a useful alternative to several other diagnostic tests.

    Full Text Available Abstract Background Non-typeable Haemophilus influenzae (NTHi and Streptococcus pneumoniae are major causes of bacterial acute otitis media (AOM. Data regarding AOM are limited in Latin America. This is the first active surveillance in a private setting in Venezuela to characterize the bacterial etiology of AOM in children Methods Between December 2008 and December 2009, 91 AOM episodes (including sporadic, recurrent and treatment failures were studied in 87 children enrolled into a medical center in Caracas, Venezuela. Middle ear fluid samples were collected either by tympanocentesis or spontaneous otorrhea swab sampling method. Standard laboratory and microbiological techniques were used to identify bacteria and test for antimicrobial resistance. The results were interpreted according to Clinical Laboratory Standards Institute (CLSI 2009 for non-meningitis isolates. All statistical analyses were performed using SAS 9.1 and Microsoft Excel (for graphical purposes. Results Overall, bacteria were cultured from 69.2% (63 of the 91 episodes; at least one pathogen (S. pneumoniae, H. influenzae, S. pyogenes or M. catarrhalis was cultured from 65.9% (60/91 of episodes. H. influenzae (55.5%; 35/63 episodes and S. pneumoniae (34.9%; 22/63 episodes were the most frequently reported bacteria. Among H. influenzae isolates, 62.9% (22/35 episodes were non-capsulated (NTHi and 31.4% (11/35 episodes were capsulated including types d, a, c and f, across all age groups. Low antibiotic resistance for H. influenzae was observed to amoxicillin/ampicillin (5.7%; 2/35 samples. NTHi was isolated in four of the six H. influenzae positive samples (66.7% from recurrent episodes. Conclusions We found H. influenzae and S. pneumoniae to be the main pathogens causing AOM in Venezuela. Pneumococcal conjugate vaccines with efficacy against these bacterial pathogens may have the potential to maximize protection against AOM.

    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.

    The aim of this work was to describe the prevalence of signs and symptoms of temporomandibular disorders (TMD) in children of the State of Puebla, Mexico. A descriptive observational study was performed. After calculating sample size, children who met the following selection criteria were included: registered at an official elementary school, either sex, ages between 8 and 12 years, who accept to participate in the study and whose parents have signed the informed consent forms. The Research Diagnostic Criteria for Temporomandibular Disorders were used by calibrated researchers (Kappa 90) under the same conditions. Descriptive statistics were applied by using SPSSv15 software. The study included 235 children, 129 (54.9%) female and 106 (45.1%) male, of average age 9.31 + 1.2 years. Prevalence of signs and symptoms was 33.2%, and predominately muscular (82%), 48.1% showed signs of muscular pain and 19.1% joint pain. 63.4% showed signs of alteration in the mouth opening pattern, 39.1% presented joint sounds on opening or closing the mouth and 20.4% on mandibular excursions. The high prevalence of signs and symptoms related to temporomandibular disorders, in particular in children with mixed dentition, shows the importance of TMD evaluation during this period, when morphological changes associated to growth and craniofacial development prevail.

    Full Text Available Background and purpose: Chronic abdominal pain is a common clinical problem in children. Apleys reported the incidence of 10-15% of chronic abdominal pain in school age children, but recent studies reported 20% of that type of pain. The aim of this study was determining the spectrum of clinical manifestations of dyspeptic children and to identify the relation between some clinical symptoms, organic or functional dyspepsia, and long term follow up of functional type.Materials and Methods: This descriptive case series study was done on 232 children between 4 and 18 years of age complaining about chronic abdominal pain chiefly who had referred to pediatric gastroenterology department of Boo-Ali Hospital of sari in 2005-2006. A checklist composed of patient demographic criteria and pain characteristics was prepared. Physical exam and laboratory tests such as AST, ALT, U/A, U/C, S/E, ESR, CBC were performed for all patients. If there were any alarming signs of organic abdominal pain-persistence or recurrence of symptoms and severe disability despite the use of H-blockers-upper GI endoscopies was indicated. Recorded data were analyzed by SPSS software and Chi- square tests.Results: 102 of 232 patients had dyspepsia; 59 were girls (9.2y/o, and 43 were boys (7.5y/o. 65 out of 102 patients had dominant abdominal pain and the rest had flatulence, vomiting and early fullness. 64 of them went under UGI endoscopies. 28 of 64 had mucosal erosion.Conclusion: Because the functional or organic abdominal pain has not unique diagnostic criteria, and the data about pathological change in children are fewer than that of adults we recommend the clinical findings and biochemical change of mucosa for differential diagnosis in children.

    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.

  4. Epidemiological causality.

    Science.gov (United States)

    Morabia, Alfredo

    2005-01-01

    Epidemiological methods, which combine population thinking and group comparisons, can primarily identify causes of disease in populations. There is therefore a tension between our intuitive notion of a cause, which we want to be deterministic and invariant at the individual level, and the epidemiological notion of causes, which are invariant only at the population level. Epidemiologists have given heretofore a pragmatic solution to this tension. Causal inference in epidemiology consists in checking the logical coherence of a causality statement and determining whether what has been found grossly contradicts what we think we already know: how strong is the association? Is there a dose-response relationship? Does the cause precede the effect? Is the effect biologically plausible? Etc. This approach to causal inference can be traced back to the English philosophers David Hume and John Stuart Mill. On the other hand, the mode of establishing causality, devised by Jakob Henle and Robert Koch, which has been fruitful in bacteriology, requires that in every instance the effect invariably follows the cause (e.g., inoculation of Koch bacillus and tuberculosis). This is incompatible with epidemiological causality which has to deal with probabilistic effects (e.g., smoking and lung cancer), and is therefore invariant only for the population.

    Full Text Available Edward J Oberle, Julia G Harris, James W VerbskyDepartment of Pediatrics, Division of Rheumatology, Medical College of Wisconsin, Milwaukee, WI, USAAbstract: Juvenile idiopathic arthritis (JIA is a group of disorders characterized by arthritis persisting for at least 6 weeks with onset before the age of 16 years. Within this cluster of conditions, the polyarticular form (involving more than four joints within the first 6 months is further divided based on the presence of rheumatoid factor. Children with polyarticular JIA pose unique diagnostic and therapeutic challenges compared to children with involvement of fewer joints. Polyarticular JIA patients tend to have a more refractory course and therefore are at increased risk for joint damage, resulting in poorer functional outcomes and decreased quality of life. Although the ability to treat this disorder continues to improve, especially with the advent of biologic agents, there is still much about the epidemiology and pathogenesis of polyarticular JIA that is unknown. The epidemiology of polyarticular JIA varies worldwide with a vast difference in reported cases between different global regions as well as within individual countries. Several genetic risk loci have been identified conferring increased susceptibility to JIA, many within the human leukocyte antigen region. Beyond the genome, environmental factors also seem to contribute to the etiology of polyarticular JIA. This review article will focus on the epidemiology and current treatments of polyarticular JIA and briefly discuss genetic and environmental influences on the pathogenesis of JIA as well as new and emerging therapies.Keywords: juvenile arthritis, polyarticular, epidemiology, treatment, rheumatology

To determine frequency of anti-cyclic citrullinated peptide antibodies (ACCP and anti-modified citrullinated vimentin antibodies (AMCV elevation and their diagnostic significance in children with early juvenile arthritis (JA. Material and methods. ACCP were evaluated in serum of 80 pts with early JA (36 girls, 44 boys, mean age 8,5±5,03 years, AMCV — in 85 pts with early JA (49 girls and 36 boys aged from 1,5 to 16 years (mean age 8,7±4,9 years. Disease duration in all children was less than 6 months. Control group included 54 grown up pts with early rheumatoid arthritis (RA, 27 - with undifferentiated arthritis (UDA and 37 conditionally healthy children. АССР was assessed by immuno-enzyme assay (IEA with commercial kits “Axis Shield Diagnostics" (Great Britain, upper normal limit 5,0 U/ml. AMCV was examined by IEA with commercial kits “Orgentec Diagnostics” (Germany, upper normal limit — 25 U/ml. Results. ACCP was elevated in 7 children with early JA (8,8%. Frequency was higher than in healthy children but lower than in grown up pts with early RA and comparable with UDA. In juvenile rheumatoid arthritis (JRA ACCP were more frequent than in juvenile chronic arthritis (JCA. Concentration was higher in rheumatoid factor (RF positive pts with polyarticular JA. AMCV level was elevated in in 23 (27,1% pts with early JA (more frequent than in healthy donors but less frequent than in grown up pts with early RA and UDA. AMCV was significantly more frequent in JRA than in JCA and in RF positive than in RF negative pts. AMCV concentration in JA was higher than in healthy children but lower than in grown up pts with RA. It was also higher in RF+ than RF- JA. ACCP and AMCV correlated with swollen joint count, tender joint count and RF. AMCV also correlated with ESR and CRP. Conclusion. In pts with early JA ACCP and AMCV are equally or more frequent than RF. In spite of low sensitivity they have high specificity for JRA in contrast

    Background The sensitivity of rapid influenza diagnostic test (RIDT) of children with influenza-like illness (ILI) remains low. Objective We compare the parameters between pandemic A(H1N1) 2009 influenza with negative RIDT and ILI not H1N1 for improving the low sensitivity of RIDT for children with ILI. Methods In a cohort of consecutive laboratory-confirmed H1N1 influenza, we identified 150 H1N1 children with positive RIDT, 152 H1N1 children with negative RIDT, and 75 children with ILI not H1N1. Viral load in throat, complete blood count (CBC), and C-reactive protein (CRP) levels between H1N1 children with negative RIDT and children with ILI not H1N1 were assessed. Results The diagnostic sensitivity of the RIDT was 45·5%. An analysis of CBC and CRP levels indicated that H1N1 children with negative RIDT had lower total leukocyte, neutrophil, lymphocyte, and basophil counts, and serum CRP levels (P < 0·01). Lymphocyte counts less than 1500 cells/mm3 and CRP levels <15 mg/l, determined by a receiver operating characteristic curve, showed a diagnostic sensitivity of 52·5% and 80·7%, respectively. Combining the lymphocyte counts and CRP levels provided a diagnostic sensitivity of 91·5%. Moreover, H1N1 children with negative RIDT had a lower viral load than those with positive RIDT (3·33 versus 4·48 log10 copies/ml, P < 0·001); the viral load was negatively correlated to the lymphocyte count (P < 0·001). Conclusions A combination of a low lymphocyte count and a low CRP level could, in the early disease phase, provide a useful screening for H1N1 children with false-negative RIDT, potentially facilitating differential diagnoses.

    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.

    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). Whilst male patients aged 6-12 years had the highest prevalence; the relative increase in prescribing was higher amongst female patients of the same age - the increase in prevalence in females aged 6–12 years was 2.1 fold

    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.

    Full Text Available Objectives. The aim of the study was to establish whether fecal calprotectin concentration (FCC may be useful in children with chronic abdominal pain to differentiate between inflammatory bowel disease (IBD, other inflammatory gastrointestinal disorders, and functional gastrointestinal disorders. Methods. The study included 163 patients (median age 13 years, who were assigned to four study groups: group 0 (control, 22 healthy children; group 1, 33 children with functional gastrointestinal disorders; group 2, 71 children with inflammatory gastrointestinal disorders other than IBD; group 3, 37 children with IBD. FCC was measured using ELISA assay. Results. In group 0 and group 1 FCCs were below 100 μg/g. Low FCCs were found in 91% of patients in group 2. In patients with IBD FCCs were markedly elevated with median value of 1191.5 μg/g. However, in children with inflammatory gastrointestinal disorders other than IBD and in children with IBD mean FCCs were significantly higher compared with the control group. Significant differences in FCCs were also found between group 1 and group 2, between group 1 and group 3, and between group 2 and group 3. Conclusion. FCC is the best parameter allowing for differentiation between IBD, other inflammatory gastrointestinal disorders, and functional gastrointestinal disorders. High FCC is associated with a high probability of IBD and/or other inflammatory gastrointestinal disorders, and it allows excluding functional gastrointestinal disorders.

    This article defines clinical epidemiology and describes its goal and objectives. The author claims that clinical epidemiology is a section of epidemiology which underlies the development of evidence-based standards for diagnostics, treatment and prevention and helps to select the appropriate algorithm for each clinical case. The study provides a comprehensive overview of the relationship between clinical epidemiology and evidence-based medicine. Epidemiological research is shown to be methodological basis of clinical epidemiology and evidence-based medicine with randomized controlled trials being the "gold standard" for obtaining reliable data. The key stages in the history of clinical epidemiology are discussed and further development of clinical epidemiology and the integration of courses on clinical epidemiology in education is outlined for progress in medical research and health care practice.

    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.

    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.

    PURPOSE Up to 50% of urinary tract infections (UTIs) in young children are missed in primary care. Urine culture is essential for diagnosis, but urine collection is often difficult. Our aim was to derive and internally validate a 2-step clinical rule using (1) symptoms and signs to select children for urine collection; and (2) symptoms, signs, and dipstick testing to guide antibiotic treatment. METHODS We recruited acutely unwell children aged under 5 years from 233 primary care sites across England and Wales. Index tests were parent-reported symptoms, clinician-reported signs, urine dipstick results, and clinician opinion of UTI likelihood (clinical diagnosis before dipstick and culture). The reference standard was microbiologically confirmed UTI cultured from a clean-catch urine sample. We calculated sensitivity, specificity, and area under the receiver operator characteristic (AUROC) curve of coefficient-based (graded severity) and points-based (dichotomized) symptom/sign logistic regression models, and we then internally validated the AUROC using bootstrapping. RESULTS Three thousand thirty-six children provided urine samples, and culture results were available for 2,740 (90%). Of these results, 60 (2.2%) were positive: the clinical diagnosis was 46.6% sensitive, with an AUROC of 0.77. Previous UTI, increasing pain/crying on passing urine, increasingly smelly urine, absence of severe cough, increasing clinician impression of severe illness, abdominal tenderness on examination, and normal findings on ear examination were associated with UTI. The validated coefficient- and points-based model AUROCs were 0.87 and 0.86, respectively, increasing to 0.90 and 0.90, respectively, by adding dipstick nitrites, leukocytes, and blood. CONCLUSIONS A clinical rule based on symptoms and signs is superior to clinician diagnosis and performs well for identifying young children for noninvasive urine sampling. Dipstick results add further diagnostic value for empiric antibiotic

    Epidemiology is the study of the distribution, determinants, and natural history of disease in populations. Epidemiology has several uses in addition to its traditional role of documenting the public health significance of a condition. Notably, epidemiologic methods and data can be used to identify and verify causes of disease. This article reviews the epidemiologic data on pain in the temporomandibular region, and on signs and symptoms associated with specific subtypes of temporomandibular disorders, with the aim of identifying possible etiologic factors for these conditions that deserve further study. Despite methodologic and population differences, several consistencies are apparent in the epidemiologic literature. Pain in the temporomandibular region appears to be relatively common, occurring in approximately 10% of the population over age 18; it is primarily a condition of young and middle-aged adults, rather than of children or the elderly, and is approximately twice as common in women as in men. This prevalence pattern suggests that etiologic investigations should be directed at biologic and psychosocial factors that are more common in women than in men, and diminish in older age groups. Most signs and symptoms associated with particular temporomandibular disorders (e.g., joint sounds, pain in the joint) also appear to be more prevalent in women than in men, although age patterns for these signs and symptoms are not as clear as for temporomandibular pain. The available data highlight the need for further research on etiologic factors associated with temporomandibular pain and with specific diagnostic subtypes of temporomandibular disorders.

    Full Text Available Tuberculosis in childhood differs from the adult clinical form and even has been suggested that it is a different disease due to its differential signs. However, prevention, diagnostics, and therapeutic efforts have been biased toward adult clinical care. Sensibility and specificity of new diagnostic approaches as GeneXpert, electronic nose (E-nose, infrared spectroscopy, accelerated mycobacterial growth induced by magnetism, and flow lateral devices in children populations are needed. Adequate and timely assessment of tuberculosis infection in childhood could diminish epidemiological burden because underdiagnosed pediatric patients can evolve to an active state and have the potential to disseminate the etiological agent Mycobacterium tuberculosis, notably increasing this worldwide public health problem.

    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

    Full Text Available Brett Ley, Harold R Collard Department of Medicine, Division of Pulmonary and Critical Care Medicine, University of California San Francisco, San Francisco, California, USA Abstract: Idiopathic pulmonary fibrosis is a chronic fibrotic lung disease of unknown cause that occurs in adults and has a poor prognosis. Its epidemiology has been difficult to study because of its rarity and evolution in diagnostic and coding practices. Though uncommon, it is likely underappreciated both in terms of its occurrence (ie, incidence, prevalence and public health impact (ie, health care costs and resource utilization. Incidence and mortality appear to be on the rise, and prevalence is expected to increase with the aging population. Potential risk factors include occupational and environmental exposures, tobacco smoking, gastroesophageal reflux, and genetic factors. An accurate understanding of its epidemiology is important, especially as novel therapies are emerging.

    Full Text Available BACKGROUND: Early recognition and prompt and appropriate antibiotic treatment can significantly reduce mortality from serious bacterial infections (SBI. The aim of this study was to evaluate the utility of five markers of infection: C-reactive protein (CRP, procalcitonin (PCT, soluble triggering receptor expressed on myeloid cells-1 (sTREM-1, CD163 and high mobility group box-1 (HMGB1, as markers of SBI in severely ill Malawian children. METHODOLOGY AND PRINCIPAL FINDINGS: Children presenting with a signs of meningitis (n = 282 or pneumonia (n = 95, were prospectively recruited. Plasma samples were taken on admission for CRP, PCT, sTREM-1 CD163 and HMGB1 and the performance characteristics of each test to diagnose SBI and to predict mortality were determined. Of 377 children, 279 (74% had SBI and 83 (22% died. Plasma CRP, PCT, CD163 and HMGB1 and were higher in HIV-infected children than in HIV-uninfected children (p<0.01. In HIV-infected children, CRP and PCT were higher in children with SBI compared to those with no detectable bacterial infection (p<0.0005, and PCT and CD163 were higher in non-survivors (p = 0.001, p = 0.05 respectively. In HIV-uninfected children, CRP and PCT were also higher in children with SBI compared to those with no detectable bacterial infection (p<0.0005, and CD163 was higher in non-survivors (p = 0.05. The best predictors of SBI were CRP and PCT, and areas under the curve (AUCs were 0.81 (95% CI 0.73-0.89 and 0.86 (95% CI 0.79-0.92 respectively. The best marker for predicting death was PCT, AUC 0.61 (95% CI 0.50-0.71. CONCLUSIONS: Admission PCT and CRP are useful markers of invasive bacterial infection in severely ill African children. The study of these markers using rapid tests in a less selected cohort would be important in this setting.

    Abstract Infectious diseases are common in internationally adopted children (IAC). With the objective to evaluate infectious diseases prevalence in a large cohort of IAC and to explore possible risk factors for tuberculosis (TB) and parasitic infections, clinical and laboratory data at first screening visit of all IAC (children (median age: 5.40 years; interquartile range: 3.00–7.90) were enrolled, 123/1612 (7.60%) having medical conditions included in the special needs definition. The most frequent cutaneous infections were Molluscum contagiosum (42/1612; 2.60%) and Tinea capitis (37/1612; 2.30%). Viral hepatitis prevalence was children, 0.80%; hepatitis C virus: 1 child, 0.10%; hepatitis A virus: 6 children, 0.40%). A parasitic infection was diagnosed in 372/1612 (23.10%) children. No risk factors for parasitosis were evidenced. Active TB was diagnosed in 4/1355 (0.3%) children, latent TB in 222/1355 (16.40%). Only 3.7% (51/1355) children had concordant positive tuberculin skin test (TST) and QuantiFERON-TB-Gold In-Tube (QFT-G-IT) results. Risk factors for TST+/QFT-G-IT− results were previous Bacille de Calmette-Guérin vaccination (adjusted odds ratio [aOR]: 2.18; 96% confidence interval [CI]: 1.26–3.79; P = 0.006), and age ≥5 years (aOR: 1.49; 95% CI: 1.06–2.11; P = 0.02). The proportion of children with nonprotective titers for vaccine-preventable diseases (VPD) ranged from 15.70% (208/1323) for tetanus to 35.10% (469/1337) for HBV. Infectious diseases were commonly observed in our cohort. The high rate of discordant TST/QFT-G results brings up questions regarding the optimal management of these children, and suggests that, at least in children older than 5 years, only QFT-G-IT results may be reliable. The low proportion of children protected for VPD, confirms importance of a timely screening. PMID:28328809

    As with most traumas, the epidemiology of the "burn" health-event has long been neglected by public health doctors and rarely considered by burns specialists. There were therefore few verified data and many approximations and preconceived ideas. The gathering of information recently undertaken in France enables the reliability of the data to be improved and the diagnostic and demographic elements relating to hospitalised patients with burns to be established.

    This chapter outlines the epidemiology of brucellosis in the Russian Federation and in five countries bordering Russia. Since the Soviet Union's dissolution, Russia and the newly formed independent republics have failed to maintain policies to control brucellosis and other zoonotic diseases. Many of these republics, due to weak animal control and prevention systems and dangerous food preparation practices, are still burdened with the human cost of brucellosis. The final summary of this section provides an example of the successful transboundary cooperative efforts between Arizona and Mexico, which could be applied to the situation between Russia and the bordering independent republics.

    ABSTRACT Asthma is a chronic disease caused by the inflammation of the main air passages of the lungs. This paper outlines a review of the published literature on asthma. While a few studies show a trend of rising asthma cases in the Caribbean region, even fewer have explored the genetic epidemiological factors of asthma. This is a literature review that seeks to sum the body of knowledge on the epidemiology of asthma. Specifically, the major objective of the literature review is to provide a unified information base on the current state of factors involved in the genetic epidemiology of asthma. The review is a simple, yet detailed summary of the literature sources and their methodology and findings on the genetic epidemiology of asthma. Further, it seeks to direct this effort to the Caribbean region. The paper then reviews a summarized and synthesized collection of the body of previous research. Of specific interest are peer-reviewed sources that have been published in recent times. The paper provides more recent insight and recapitulates on the previous research, while tracing the intellectual progress on the debate. Where possible, reviewing and discussing the results of the previous literature, this review singles out the gaps and potential future research directions for studying the genetic epidemiology of asthma. Overall, we hope to contribute to a more synthesized knowledge and improved understanding of the previous literature and future potential direction of genetic and epidemiological asthma research.

    CT and MRI are both used for abdominal staging of pediatric renal tumors. The diagnostic performance of the two modalities for local and regional staging of renal tumors has not been systematically evaluated. 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.)

    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.

    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

    Full Text Available Abstract Background This was a method comparison study. The aim of study was to compare caries information obtained from a full mouth visual examination using the method developed by the British Association for the Study of Community Dentistry (BASCD for epidemiological surveys with caries data obtained from eight, six and four intra-oral digital photographs of index teeth in two groups of children aged 5 years and 10/11 years. Methods Five trained and calibrated examiners visually examined the whole mouth of 240 5-year-olds and 250 10-/11-year-olds using the BASCD method. The children also had intra-oral digital photographs taken of index teeth. The same 5 examiners assessed the intra-oral digital photographs (in groups of 8, 6 and 4 intra-oral photographs for caries using the BASCD criteria; dmft/DMFT were used to compute Weighted Kappa Statistic as a measure of intra-examiner reliability and intra-class correlation coefficients as a measure of inter-examiner reliability for each method. A method comparison analysis was performed to determine the 95% limits of agreement for all five examiners, comparing the visual examination method with the photographic assessment method using 8, 6 and 4 intra-oral photographs. Results The intra-rater reliability for the visual examinations ranged from 0.81 to 0.94 in the 5-year-olds and 0.90 to 0.97 in the 10-/11-year-olds. Those for the photographic assessments in the 5-year-olds were for 8 intra-oral photographs, 0.86 to 0.94, for 6 intra-oral photographs, 0.85 to 0.98 and for 4 intra-oral photographs, 0.80 to 0.96; for the 10-/11-year-olds were for 8 intra-oral photographs 0.84 to 1.00, for 6 intra-oral photographs 0.82 to 1.00 and for 4 intra-oral photographs 0.72 to 0.98. The 95% limits of agreement were −1.997 to 1.967, -2.375 to 2.735 and −2.250 to 2.921 respectively for the 5-year-olds and −2.614 to 2.027, -2.179 to 3.887 and −2.594 to 2.163 respectively for the 10-/11-year

    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.

    The problem of treatment of periodontitis remains one of the hot topics in practical stomatology. It has been established that modern adaptogenic infection is rather aggressive to whole organism of a human being. All these demands accurate approach while choosing of a conservative method of treatment for such forms as acute and chronic periodontitis. There were 27 children under observation with diabetes mellitus of type 1 (I group). Mean age was 10.5+/-0.75 years. 15 were girls and 13 boys. All patients from the I group were examined for the pathologies of oral cavity. In 100% dryness in a mouth and in 67% bleeding from the gum had been revealed. The mild form of chronic catarrhal gingivitis was revealed in 12 patients, moderate in 5, chronic hypertrophic gingivitis in 8 respectively. Studying of pH of saliva and lactate dehydrogenase (LDH) activity in children with periodontitis developed on the background of recently diagnosed type 1 diabetes mellitus has shown, that pH of saliva was equal to 5.3+/-0.18. In control group (healthy children) pH of saliva was 6.8+/-0.06. In the conclusion it should be emphasized, that we have tried to explain some aspects of multiple character of development of periodontitis at recently discovered insulin-depended diabetes mellitus. Character of changes of some properties of saliva pH and of enzyme activity of LDG promotes to carrying out medical and preventive actions, influencing the main blocks of pathogenesis of this pathological process. Besides, we consider possibility of inclusion the studied parameters of mixed saliva in the algorithm of investigation of periodontitis in children with recently diagnosed type 1 diabetes mellitus.

    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 febrile neutropenia; however, persistent high serum suPAR level may predict mortality in FN in children.

    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.)

    AIM: To evaluate the maximal-outer-diameter (MOD) and the maximal-mural-thickness (MMT) of the appendix in children with acute appendicitis and to determine their optimal cut-off values to diagnose acute appendicitis. METHODS: In total, 164 appendixes from 160 children between 1 and 17 years old (84 males, 76 females; mean age, 7.38 years) were examined by high-resolution abdominal ultrasound for acute abdominal pain and the suspicion of acute appendicitis. We measured the MOD and the MMT at the thickest point of the appendix. Patients were categorized into two groups according to their medical records: patients who had surgery (surgical appendix group) and patients who did not have surgery (non-surgical appendix group). Data were analyzed by MedCalc v.9.3. The rank sum test (Mann-Whitney test) was used to evaluate the difference in the MOD and the MMT between the two groups. ROC curve analysis was used to determine the optimal cut-off value of the MOD and the MMT on diagnosis of acute appendicitis.RESULTS: There were 121 appendixes (73.8%) in the non-surgical appendix group and 43 appendixes (26.2%) in the surgical appendix group. The median 26.2%) in the surgical appendix group. The median MOD differed significantly between the two groups (0.37 cm vs 0.76 cm, P 0.57 cm (sensitivity 95.4%, specificity 93.4%) and > 0.22 cm (sensitivity 90.7%, specificity 79.3%), respectively. CONCLUSION: The MOD and the MMT are reliable criteria to diagnose acute appendicitis in children. An MOD > 0.57 cm and an MMT > 0.22 cm are the optimal criteria.

Although FC is a common childhood problem, its global burden remains unknown as data from parts of the world are missing. Another problem is that there is a large variation in prevalence due to differences in study methods and defining age groups. The pathophysiology of FC remains unclear to date but is probably multifactorial. Withholding behavior is likely to be the most important factor in toddlers and young children. Genetics may also play a role since many patients have positive family history, but mutations in genes associated with FC have not been found. Over the past years, different diagnostic criteria for FC in infants and children have been proposed. This year, Rome IV criteria have been released. Compared to Rome III, it eliminates two diagnostic criteria in children under the age of 4 who still wear diapers. Physical examination and taking a thorough medical history are recommended, but other investigations such as abdominal radiography, transabdominal recto-ultrasonography, colonic transit time, rectal biopsies, and colon manometry are not routinely recommended. Regarding treatment, guidelines recommend disimpaction and maintenance therapy with polyethylene glycol (PEG with or without electrolytes. But experience shows that acceptability, adherence, and tolerance to PEG are still a challenge. Counseling of parents and children about causes of FC is often neglected. Recent studies suggest that behavior therapy added to laxative therapy improves the relief of symptoms. Further homogeneous studies, better-defined outcomes, and studies

    2013-06-01

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

    2016-05-01

    In order to solve public health problems posed by the epidemiology of risk factors centered on the individual and neglecting the causal processes linking the risk factors with the health outcomes, Mervyn Susser proposed a multilevel epidemiology called eco-epidemiology, addressing the interdependence of individuals and their connection with molecular, individual, societal, environmental levels of organization participating in the causal disease processes. The aim of this epidemiology is to integrate more than a level of organization in design, analysis and interpretation of health problems. After presenting the main criticisms of risk-factor epidemiology focused on the individual, we will try to show how eco-epidemiology and its development could help to understand the need for a broader and integrative epidemiology, in which studies designed to identify risk factors would be balanced by studies designed to answer other questions equally vital to public health.

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

    Objective: To analysis the epidemiologic features on fall injury between migrant and native children. This information would provide the scientific basis for the prevention and control of fall injury. Methods: The features were retrospectively analyzed on fall injury between migrating and native children aged 0-6 years through the injury surveillance network in Guangzhou. Results: Boys aged 3-6 years prone to fall, more children from kindergarten fell than children living scattered. Comparing with native children, migrant boy had a higher rate of falling, more migrant children in the middle or large class, and the kind of their families mostly was nuclear family. More migrant children fell in summer than native children, while more native children in spring or winter. Comparing with native children, migrant children had a higher rate of falling when they were playing or had recreation activities, more migrant children had parnets as their caregivers, and they were more likely to get some treatment at home. More native children fell when being take care by teachers or got treatment in the infirmary than migrant children.

    Unenhanced MRI has emerged as a useful tool for diagnosing pediatric acute appendicitis. The use of contrast-enhanced MRI for diagnosing pediatric appendicitis has not been documented. The purpose of this study is to examine the diagnostic performance of contrast-enhanced MRI for acute appendicitis and alternative entities in the pediatric population presenting with acute abdominal pain. A retrospective review was conducted of 364 consecutive pediatric patients undergoing contrast-enhanced MRI for the evaluation of possible appendicitis at a single institution between November 2012 and September 2013. There were 132 cases of pathologically confirmed appendicitis out of 364 pediatric patients (36.3%) included in the study. Overall sensitivity and specificity were 96.2% (95% CI [91.4-98.4%]) and 95.7% (95% CI [92.3-97.6%]), respectively. Positive predictive value and negative predictive value were 92.7% (95% CI [86.6-96.3%]) and 97.8% (95% CI [94.7-99.1%]), respectively. The appendix was visualized in 243 cases (66.8%). Imaging confirmed alternative diagnoses in 75 patients, including most commonly colitis, enteritis or terminal ileitis (n = 25, 6.9%), adnexal cysts (n = 25, 6.9%) and mesenteric adenitis (n = 7, 1.9%). Contrast-enhanced MRI is capable of accurately diagnosing acute appendicitis while detecting many alternative entities of abdominal pain, and it allows good visualization of the appendix. Further evaluation is needed to determine whether contrast-enhanced MRI provides an advantage over non-enhanced MRI for imaging evaluation of acute abdominal pain in the pediatric population.

    Objectives To compare the validity of diagnosis of urinary tract infection (UTI) through urine culture between samples processed in routine health service laboratories and those processed in a research laboratory. Population and methods We conducted a prospective diagnostic cohort study in 4808 acutely ill children aged <5 years attending UK primary health care. UTI, defined as pure/predominant growth ≥105 CFU/mL of a uropathogen (the reference standard), was diagnosed at routine health service laboratories and a central research laboratory by culture of urine samples. We calculated areas under the receiver-operator curve (AUC) for UTI predicted by pre-specified symptoms, signs and dipstick test results (the “index test”), separately according to whether samples were obtained by clean catch or nappy (diaper) pads. Results 251 (5.2%) and 88 (1.8%) children were classified as UTI positive by health service and research laboratories respectively. Agreement between laboratories was moderate (kappa = 0.36; 95% confidence interval [CI] 0.29, 0.43), and better for clean catch (0.54; 0.45, 0.63) than nappy pad samples (0.20; 0.12, 0.28). In clean catch samples, the AUC was lower for health service laboratories (AUC = 0.75; 95% CI 0.69, 0.80) than the research laboratory (0.86; 0.79, 0.92). Values of AUC were lower in nappy pad samples (0.65 [0.61, 0.70] and 0.79 [0.70, 0.88] for health service and research laboratory positivity, respectively) than clean catch samples. Conclusions The agreement of microbiological diagnosis of UTI comparing routine health service laboratories with a research laboratory was moderate for clean catch samples and poor for nappy pad samples and reliability is lower for nappy pad than for clean catch samples. Positive results from the research laboratory appear more likely to reflect real UTIs than those from routine health service laboratories, many of which (particularly from nappy pad samples) could be due to contamination.

    BACKGROUND It is not clear which young children presenting acutely unwell to primary care should be investigated for urinary tract infection (UTI) and whether or not dipstick testing should be used to inform antibiotic treatment. OBJECTIVES To develop algorithms to accurately identify pre-school children in whom urine should be obtained; assess whether or not dipstick urinalysis provides additional diagnostic information; and model algorithm cost-effectiveness. DESIGN Multicentre, prospective diagnostic cohort study. SETTING AND PARTICIPANTS Children < 5 years old presenting to primary care with an acute illness and/or new urinary symptoms. METHODS One hundred and seven clinical characteristics (index tests) were recorded from the child's past medical history, symptoms, physical examination signs and urine dipstick test. Prior to dipstick results clinician opinion of UTI likelihood ('clinical diagnosis') and urine sampling and treatment intentions ('clinical judgement') were recorded. All index tests were measured blind to the reference standard, defined as a pure or predominant uropathogen cultured at ≥ 10(5) colony-forming units (CFU)/ml in a single research laboratory. Urine was collected by clean catch (preferred) or nappy pad. Index tests were sequentially evaluated in two groups, stratified by urine collection method: parent-reported symptoms with clinician-reported signs, and urine dipstick results. Diagnostic accuracy was quantified using area under receiver operating characteristic curve (AUROC) with 95% confidence interval (CI) and bootstrap-validated AUROC, and compared with the 'clinician diagnosis' AUROC. Decision-analytic models were used to identify optimal urine sampling strategy compared with 'clinical judgement'. RESULTS A total of 7163 children were recruited, of whom 50% were female and 49% were < 2 years old. Culture results were available for 5017 (70%); 2740 children provided clean-catch samples, 94% of whom were ≥ 2 years old

    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.

    Full Text Available Among the over 90 serotypes of Streptococcus pneumoniae described, serotypes 1, 5, and 7F account for a significant proportion of invasive disease worldwide and are now covered by the most recent 10- and 13-valent pneumococcal conjugate vaccines (PCVs. 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.

    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.

    Neurobrucellosis is a complication of brucellosis,which is considered endemic in the Indian subcontinent,Arabian Peninsula and Mediterranean countries.Brucella reaches the central nervous system via hematogenous spread in the infected human being,or through phagocytosis.Neurobrucellosis can present with any neurological symptoms,hence,the index of suspicion must be high enough to make proper diagnosis.Cerebrospinal fluid studies are usually diagnostic,while imagings including magnetic resonance imaging and computed tomography are of little assistance.As for therapy,a combination of antibiotics must be administered with a goal to reduce relapse or avoid failure.The duration of treatment should be tailored as per clinical signs and symptoms until the cerebrospinal fluid components return to normal,which might be up to six months.In this article,we present an overall view of current understanding of neurobrucellosis in children,its epidemiology,clinical features,diagnostictests,and management options.

    A large body of literature on diminished ejaculatory disorders has been generated without the use of a clear diagnostic definition. Many studies have not distinguished between the orgasm and ejaculation disorders leading to doubtful results. Delayed ejaculation (DE) is one of the diminished ejaculatory disorders, which range from varying delays in ejaculatory latency to a complete inability to ejaculate. The present review is aimed at providing a comprehensive overview of the current knowledge on the definition and epidemiology of diminished ejaculatory disorders. We focus on the acquired diseases, such as benign prostatic hyperplasia (BPH) and specific drug regimens that may cause an iatrogenic form of ejaculatory disorder. In addition, the impact of aging is discussed since the prevalence of DE appears to be moderately but positively related to age. Finally, we also focus on the importance of the hormonal milieu on male ejaculation. To date, evidence on the endocrine control of ejaculation is derived from small clinical trials, but the evidence suggests that hormones modulate the ejaculatory process by altering its overall latency.

    We assessed vaccine effectiveness (VE) against medically attended, laboratory-confirmed influenza in children 6 months to 15 years of age in 22 hospitals in Japan during the 2013-14 season. Our study was conducted according to a test-negative case-control design based on influenza rapid diagnostic test (IRDT) results. Outpatients who came to our clinics with a fever of 38 °C or over and had undergone an IRDT were enrolled in this study. Patients with positive IRDT results were recorded as cases, and patients with negative results were recorded as controls. Between November 2013 and March 2014, a total of 4727 pediatric patients (6 months to 15 years of age) were enrolled: 876 were positive for influenza A, 66 for A(H1N1)pdm09 and in the other 810 the subtype was unknown; 1405 were positive for influenza B; and 2445 were negative for influenza. Overall VE was 46% (95% confidence interval [CI], 39-52). Adjusted VE against influenza A, influenza A(H1N1)pdm09, and influenza B was 63% (95% CI, 56-69), 77% (95% CI, 59-87), and 26% (95% CI, 14-36), respectively. Influenza vaccine was not effective against either influenza A or influenza B in infants 6 to 11 months of age. Two doses of influenza vaccine provided better protection against influenza A infection than a single dose did. VE against hospitalization influenza A infection was 76%. Influenza vaccine was effective against influenza A, especially against influenza A(H1N1)pdm09, but was much less effective against influenza B.

    Full Text Available Understanding the etiology of a disease such as prostate cancer may help in identifying populations at high risk, timely intervention of the disease, and proper treatment. Biomarkers, along with exposure history and clinical data, are useful tools to achieve these goals. Individual risk and population incidence of prostate cancer result from the intervention of genetic susceptibility and exposure. Biochemical, epigenetic, genetic, and imaging biomarkers are used to identify people at high risk for developing prostate cancer. In cancer epidemiology, epigenetic biomarkers offer advantages over other types of biomarkers because they are expressed against a person’s genetic background and environmental exposure, and because abnormal events occur early in cancer development, which includes several epigenetic alterations in cancer cells. This article describes different biomarkers that have potential use in studying the epidemiology of prostate cancer. We also discuss the characteristics of an ideal biomarker for prostate cancer, and technologies utilized for biomarker assays. Among epigenetic biomarkers, most reports indicate GSTP1 hypermethylation as the diagnostic marker for prostate cancer; however, NKX2-5, CLSTN1, SPOCK2, SLC16A12, DPYS, and NSE1 also have been reported to be regulated by methylation mechanisms in prostate cancer. Current challenges in utilization of biomarkers in prostate cancer diagnosis and epidemiologic studies and potential solutions also are discussed.

Methods; Conners Parent Symptom Questionnaire ( PSQ ) and a self - designed questionnaire about the effect factors of children behaviors were used to survey 724 children aged 3 ~ 7 years old in urban area and rural area of Zhenjiang city. Results: The detection rate of behavior problems in children aged 3 ~ 7 years old was 13. 1% , the detection rates of behavior problems in boys and girls were 17. 0% and 9. 2% , respectively, there was significant difference (P<0. 01) . There was significant difference in character problems between boys and girls (P<0. 05) . There was also significant difference in impulse, hyperactivity and hyperactive index between boys and girls (P <0. 01) . Univariate analysis found that the effect factors of behavior problems in children aged 3 ~ 7 years old included maternal anxiety or depression during pregnancy, physical health state during pregnancy, paternal educational level, complications during perinatal period, past medical history of children and the time of starting to speak of children. Multivariate stepwise regression analysis found that maternal anxiety or depression during pregnancy, poor physical health state during pregnancy and complications during perinatal period were the main risk factors of behavior problems in children. Conclusion: The behavior problems of children aged 3 ~7 years old are resulted from multiple factors, keeping good maternal spirit and reducing complications during perinatal period have important significances to reduce the behavior problems of children.%目的:探讨镇江市3~7岁儿童行为问题的流行病学特点,为减少儿童行为问题的发生提供干预措施.方法:应用Conners父母症状问卷(Parent Symptom Questionnaire,PSQ)和自编儿童

    Objective To investigate and analyze the molecular epidemiology of enteric adenovirus infection in the children with diarrhea in Shaoguan. Methods 250 children with diarrhea in Shaoguan from January 2010 to December 2013 were selected as the study subjects and their diarrhea feces were collected to receive adenovirus detection. Results Twelve children with enteric adenovirus infection were detected, with a positive rate of 4.80%(12/250). Of the 12 children with enteric adenovirus infection(EAdV), 9 children had type 41 enteric adenovirus infection, accounting for 3.60%(9/250). Three children had type 40 enteric adenovirus infection, accounting for 1.20%(3/250). Enteric adenovirus infection mainly concentrated in the infants and young children under the age of 2 years, and its attack rate was not obviously related to the sex, residence, season and other factors, with no significant differences(P>0.05). The children mainly displayed fever, diarrhea and vomiting symptoms. Conclusion Enteric adenovirus infection is an important cause of diarrhea in children and is mainly caused by type 41 enteric adenovirus. Enhancing monitoring of infants and young children and offering timely and specific treatment once infection occurs are of important significance to improving the children's state of illness and promoting prognosis.%目的:对韶关市腹泻患儿肠道腺病毒感染进行分子流行病学调查分析。方法选取2010年1月~2013年12月韶关市腹泻患儿250例作为研究对象,收集其腹泻粪便并展开腺病毒检测。结果本次研究结果共检测出12例肠道腺病毒感染患儿,阳性率为4.80%(12/250)。12例肠道腺病毒(EAdV)感染患儿中,属于肠道腺病毒41型的9例,占3.60%(9/250)。属于肠道腺病毒40型的3例,占1.20%(3/250)。腺病毒感染主要集中在2岁以下的婴幼儿儿童,且发病率与性别、居住地、季节等因素之间无明显的联系,差异不显著(P>0.05)

    Only a little data is available so far on the prevalence of Asperger's syndrome. The prevalence that Fombonne (2003) estimated after considering six European research was 2/10,000. In Ishikawa's study (2006) conducted in Nagoya city, Japan, the prevalence of Asperger's syndrome was 56/10,000. Currently there are not strict diagnostic criteria of Asperger's syndrome and methods of investigation are not consistent in each study. Therefore the prevalence rate for Asperger's syndrome covered very wide range. Although we still don't have a precise prevalence data on Asperger's syndrome, the awareness of this syndrome emerged in these several decades tells us that further research and support for the children of Asperger's syndrome and their family are necessary.
