Nonsymptomatic Generalized Epilepsy in Children Younger than Six Years: Excellent Prognosis, but Classification Should Be Reconsidered after Follow-up: The Dutch Study of Epilepsy in Childhood

EPILEPSIA, Issue 7 2002
C. M. Middeldorp
Summary: ,Purpose: To assess the prognosis and the accuracy of the epilepsy classification in young children with nonsymptomatic generalized epilepsy. Methods: Of the cohort of the Dutch Study of Epilepsy in Childhood (n = 466), all children younger than 6 years with a diagnosis of idiopathic (IGE) or cryptogenic (CGE) generalized epilepsy either at intake (n = 108) and/or after 2 years of follow-up (n = 102) were included. The number of reclassifications after 2 years was determined, and the reasons for reclassification were analyzed. All children receiving a diagnosis of IGE or CGE at 2 years were followed up for 5 years to study their outcome in terms of terminal remission (TR). Data on their level of intellectual functioning were collected at the start of this analysis. Results: The epilepsy syndrome was reclassified in 17 children. In 14 of them, the seizure type also was reclassified, and in three, the course of the epilepsy determined the new epilepsy type. Two other children had a reclassification of their seizure types without a change of the epilepsy type. Many children were categorized as having IGE not otherwise specified. In all probability, this is a heterogeneous group, containing patients with various epilepsy syndromes, with generalized tonic,clonic seizures as a common hallmark. Of the 102 children with IGE or CGE at 2 years of follow-up, 75% had a TR of >6 months after 2 years, and 85% a TR of ,1 year after 5 years. Conclusions: In a fair proportion of children with nonsymptomatic generalized epilepsy in this age group, it is not possible to classify firmly the epilepsy and/or the seizures immediately after the intake. Instead, they are reclassified during the course of the disease. This and the apparent heterogeneity of the category IGE not otherwise specified point to inherent drawbacks of the current International League Against Epilepsy (ILAE) classification of epilepsy and epileptic syndromes. The prognosis of IGE at this young age is generally excellent. [source]

Suicidal Behavior in Children Younger than Twelve: A Diagnostic Challenge for Emergency Department Personnel

ACADEMIC EMERGENCY MEDICINE, Issue 9 2007
Carl L. Tishler PhD
Suicide is one of the leading causes of death in children younger than 12 years and is the fourth leading cause of death in 12 year olds. Increasing numbers of young children now present to the emergency department (ED) with mental health issues, and ED personnel must determine the most appropriate disposition options for these children, sometimes without the assistance of specialty mental health services. Much of the present body of literature describing suicidality fails to separate children from adolescents for analysis and discussion. This article reviews relevant literature pertaining to suicidal thoughts and behaviors in young children and discusses problems with available data, as well as epidemiology, risk factors, typical motivations, methods, assessment, and disposition for these patients. Suicidal children younger than 12 years are often clinically different from suicidal adolescents and adults and may require unique assessment and disposition strategies in the ED. A child who has ideation without a clear plan, or has made an attempt of low lethality, can sometimes be discharged home, provided that a supportive, responsible caregiver is willing to monitor the child and take him or her to outpatient mental health appointments. If the home environment is detrimental, or the child has used a method of high potential lethality, inpatient treatment is the most appropriate course of action. Mental health specialty services, when available, should be used to help determine the most appropriate disposition. [source]

Influenza A in Young Children with Suspected Respiratory Syncytial Virus Infection

ACADEMIC EMERGENCY MEDICINE, Issue 12 2003
Marla J. Friedman DO
Objectives: To determine the prevalence of influenza A in young children suspected of having respiratory syncytial virus (RSV) infection and to compare the clinical presentation of these patients with those who have proven RSV infection. Methods: Children younger than or at 36 months of age who presented to a pediatric emergency department (ED) with suspected RSV infection during the influenza A season of 2001,2002 were eligible. Eligible children had an RSV antigen test ordered as part of their initial clinical management. A consecutive sample of children was enrolled for prospective observational analysis. The main outcome measure was the prevalence of influenza A in young children with suspected RSV infection. The secondary outcome measure was a comparison of the clinical presentations, of the two groups. Results: During the study period, 420 patients presented for evaluation of respiratory illness. RSV tests were ordered on 251 patients. Of 197 eligible patients, 124 (63%) tested positive for RSV and 33 (17%) for influenza A. Influenza A patients were more likely to have temperatures at or above 39°C than RSV patients (36% vs. 15%; p = 0.01). RSV patients were more tachypneic (54 vs. 43 breaths/minute; p < 0.0001) and more often had wheezing (90% vs. 8%; p < 0.0001). Twenty influenza patients (61%) were hospitalized. Conclusions: This study found a high prevalence of influenza A in young children suspected of having RSV infection. Clinicians should consider influenza A in young febrile children presenting with respiratory illnesses. [source]

Seasonal Variation in Fluoride Intake: the Iowa Fluoride Study

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 4 2004
Barbara Broffitt MS;
ABSTRACT Objectives: Although patterns of fluid intake change seasonally, little is known about how fluoride intake varies by season. Since even short-term increases in fluoride intake could potentially lead to more dental fluorosis, it is valuable to assess the degree of seasonal variation to determine if it increases fluoride intake to levels that could be considered a concern in young children. Methods: Questionnaires were mailed periodically to participants in the Iowa Fluoride Study beginning at 6 weeks of age and continuing for a number of years. Parents recorded the date; child's weight; estimates of the amounts of water and other beverages that their child consumed per week; the type and amount of any fluoride supplements used; and the type, amount, and frequency of dentifrice used, with an estimate of the proportion of dentifrice that was swallowed. Documented water fluoride levels from municipal sources and assay of individual sources were linked to water intake amounts. Total fluoride intake per kg body weight was estimated from water, other beverages, fluoride supplements, and ingested dentifrice. Generalized linear models compared temperature-related and seasonal effects after adjusting for the child's age. Results: Separate analyses for ages 0,12 months and 12,72 months showed different results. Children younger than 12 months of age did not exhibit significant seasonal or temperature-related variation in any of the components of fluoride intake. Children aged 12,72 months had higher fluoride intake (mg F/kg bw) from beverages in summer (P <.05), and fluoride intake from beverages increased with monthly temperature (P <.001). Conclusions: Fluoride intake from beverages for children aged 12,72 months is slightly higher in the summer and increases with mean monthly temperature. Fluoride intake from supplements and dentifrice did not change significantly with either season or temperature. [source]

Fatal Passenger Vehicle Crashes With At Least 1 Driver Younger Than 15 Years: A Fatality Analysis Reporting System Study

THE JOURNAL OF RURAL HEALTH, Issue 2 2007
Larry Frisch MD
ABSTRACT:,Context: A small number of fatalities continue to occur due to motor vehicle crashes on highways in which at least 1 passenger vehicle (automobile, van, or small truck) is driven by a child younger than 15 years. Purpose: The purpose of this study was to extend previous work suggesting that such crashes occur frequently in the Southern states and have relatively high rates in rural areas in the South and Great Plains. Methods: This study utilizes data for the 5-year period 1999-2003 from the National Highway Transportation Safety Administration's online Fatality Analysis Reporting System. All cases were identified in which at least 1 conventional passenger vehicle in a fatal crash was being driven by a child younger than 15 years. Findings: During the 5-year period, 350 fatal crashes occurred with at least 1 driver younger than 15 years involved. Twenty-one of these drivers were licensed (11) or driving with a learner's permit (10). A total of 987 individuals in 419 vehicles were involved in these crashes, and 402 deaths resulted (1.16 deaths/crash). These crashes occurred primarily in Texas, Florida, Arkansas, and Arizona, but the highest rates per 100,000 children were found in North and South Dakota and predominantly in a band of Intermountain and Plains states. There was a strong correlation between crash rates and several measures of rurality. Conclusions: Crashes involving young, largely unlicensed, drivers account for about 70 deaths yearly. [source]

Nonsymptomatic Generalized Epilepsy in Children Younger than Six Years: Excellent Prognosis, but Classification Should Be Reconsidered after Follow-up: The Dutch Study of Epilepsy in Childhood

Intrafamilial transmission of hepatitis C in Egypt,

HEPATOLOGY, Issue 3 2005
Mostafa K. Mohamed
The incidence of hepatitis C (HCV) infection and associated risk factors were prospectively assessed in a cohort of 6,734 Egyptians from 2 rural villages who were negative for antibodies to HCV (anti-HCV). Initial and follow-up sera were tested for anti-HCV by enzyme immunoassay (EIA), and possible incident cases were confirmed by using the microparticle enzyme immunoassay (MEIA) and tested for HCV RNA. All follow-up serum samples converting from negative to positive without detectable HCV-RNA were further tested by recombinant immunoblot assay. Over an average of 1.6 years, asymptomatic anti-HCV seroconversion occurred in 33 people (3.1/1,000 person-years [PY]), including 28 (6.8/1,000 PY) in the Nile Delta village (AES), where prevalence was 24% and 5 (0.8/1,000 PY) in the Upper Egypt village (baseline prevalence of 9%). The strongest predictor of incident HCV was having an anti-HCV,positive family member. Among those that did, incidence was 5.8/1,000 PY, compared (P < .001) with 1.0/1,000 PY; 27 of 33 incident cases had an anti-HCV,positive family member. Parenteral exposures increased the risk of HCV but were not statistically significant; 67% of seroconverters were younger than 20 years of age, and the highest incidence rate (14.1/1,000 PY) was in children younger than 10 who were living in AES households with an anti-HCV,positive parent. In conclusion, young children would especially benefit from measures reducing exposures or preventing infection with HCV. (HEPATOLOGY 2005.) [source]

The burden of paediatric stroke and cerebrovascular disorders in Croatia

INTERNATIONAL JOURNAL OF STROKE, Issue 5 2009
J. Lenicek Krleza
Pediatric stroke is significantly less common than stroke in adults, but represents a major challenge to public health authorities. The aim of this retrospective study was to identify the total and annual number of children younger than 18 years with arterial ischaemic stroke and transient ischaemic attack referred to the Children's Hospital Zagreb, which is a major national centre specialised for the treatment and prevention of stroke in children. We reviewed the medical records of the Department of Neuropediatrics database at the Children's Hospital Zagreb between 1998,2005 in order to provide demographic and clinical characteristics and neuroimaging findings in children with arterial ischaemic stroke. In the 7-year period, we identified a total of 124 children from different geographic areas of Croatia with a confirmed diagnosis of transient ischaemic attack (N=77), and arterial ischaemic stroke (N=47). Perinatal and childhood arterial ischaemic stroke were equally represented (23 and 24 children, respectively). The average number of new cases identified each year was 18 cases (range: 12,21), seven arterial ischaemic stroke and 11 transient ischaemic attack cases. Male predominance was found in children with arterial ischaemic stroke with a male : female ratio of 1·76 : 1, and was slightly higher in childhood arterial ischaemic stroke compared with perinatal arterial ischaemic stroke (2 : 1 and 1·56 : 1, respectively). In contrast, transient ischaemic attack was more frequently found in girls, and more likely identified in older children compared with younger children with arterial ischaemic stroke. Obtained data will contribute to better understanding of paediatric stroke in Croatia and will provide a base for the establishment of the national referral center and national pediatric stroke registry.

Fluoride Intake and Prevalence of Dental Fluorosis: Trends in Fluoride Intake with Special Attention to Infants: REVIEW & COMMENTARY

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 3 2000
Samuel J. Fomon MD
ABSTRACT Background : Although the predominant beneficial effect of fluoride occurs locally in the mouth, the adverse effect, dental fluorosis, occurs by the systemic route. The caries attack rate in industrialized countries, including the United States and Canada, has decreased dramatically over the past 40 years. However, the prevalence of dental fluorosis in the United States has increased during the last 30 years both in communities with fluoridated water and in communities with nonfluoridated water. Dental fluorosis is closely associated with fluoride intake during the period of tooth development. Methods: We reviewed the major changes in infant feeding practices that have occurred since 1930 and the changes in fluoride intakes by infants and young children associated with changes in feeding practices. Results and Conclusions: Based on this review, we conclude that fluoride intakes of infants and children have shown a rather steady increase since 1930, are likely to continue to increase, and will be associated with further increase in the prevalence of enamel fluorosis unless intervention measures are instituted. Recommendations: We believe the most important measures that should be undertaken are (1) use, when feasible, of water low in fluoride for dilution of infant formulas; (2) adult supervision of toothbrushing by children younger than 5 years of age; and (3) changes in recommendations for administration of fluoride supplements so that such supplements are not given to infants and more stringent criteria are applied for administration to children.

Water Consumption and Nursing Characteristics of Infants by Race and Ethnicity

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 3 2000
Keith E. Heller DDS
Abstract Objective: The purpose of this project was to determine racial/ethnic differences in water consumption levels and nursing habits of children younger than 2 years old. Methods: Data from the 1994,96 Continuing Survey of Food Intakes by Individuals (CSFII) were used for these analyses. Water consumption and breast-feeding data on 946 children younger than 2 years old were used. Results: For black non-Hispanic children younger than 2 years old (n=121), 5.3 percent of the children were currently being breast fed. This percentage was less than that seen in other racial/ethnic groups. For white non-Hispanic children (n=620), this percentage was 10.8 percent; for Hispanic children (n=146), 12.2 percent; for "other" children, 18.5 percent (n=59). Black non-Hispanic children had the highest total water consumption (128.6 ml/kg/day) among all groups, white non-Hispanic had the lowest (113.2 ml/kg/day). These differences were not statistically significant in multivariate regression modeling. Black non-Hispanic children also drank moretap water (21.3 ml/kg/day) than white non-Hispanic children (12.7 ml/kg/day) and Hispanic children (14.9 ml/kg/day). The difference was statistically significant in multivariate regression modeling. Conclusions: The differences in breast feeding and water consumption observed among black children younger than 2 years of age could be a factor in the observed higher levels of fluorosis in black children compared to other children.

Micronutrients and Child Health: Studies in International Nutrition and HIV Infection

NUTRITION REVIEWS, Issue 11 2001
Christopher Duggan M.D., M.P.H.
Increasing data link micronutrient deficiencies to excess childhood morbidity and mortality, and similar relationships have been noted in the study of nutrition and HIV infection. We review epidemiologic studies that have examined the relationship between micronutrient deficiencies and health outcomes in childhood and HIV infection, as well as clinical trials of micronutrient supplementation. Vitamin A supplementation among communities at risk of deficiency effectively reduces mortality and morbidity in children younger than age 5, and vitamin A may be especially effective in HIV-infected children. Vertical transmission of HIV has not to date been affected by maternal micronutrient supplementation. In children with poor dietary zinc intake and/or bioavailability, zinc supplementation reduces the incidence and severity of diarrheal diseases, as well as the occurrence of pneumonia. Vitamin A therapy has not been associated with improved growth, whereas some trials have shown that zinc supplementation is associated with greater increments in height. Further trials of micronutrient supplementation are warranted. [source]

Clinical and Therapeutic Approach to Childhood Acne: An Update

PEDIATRIC DERMATOLOGY, Issue 4 2009
C. Antoniou M.D., Ph.D.
Childhood acne can be classified in neonatal, infantile, mid-childhood, and prepubertal acne, depending on the age of onset. In this review we will present an update on the clinical approach and therapeutic options when facing prepubertal acne in a child. The use of tetracyclines is contraindicated in children younger than 8 years, and oral isotretinoin is not recommended in children younger than 12 years of age according to the FDA and the European Commission. Nevertheless, there are case reports of 10 patients successfully treated with oral isotretinoin for recalcitrant infantile acne with scarring. Further studies are needed to investigate whether isotretinoin may improve the long-term prognosis of infantile acne, which may be associated with more severe acne in adolescence. [source]

Short-term effects of coping skills training in school-age children with type 1 diabetes

PEDIATRIC DIABETES, Issue 3pt2 2008
Jodie M Ambrosino
Objective:, Little is known about the use of psychosocial interventions in children younger than adolescence with type 1 diabetes (T1D) and their parents. We report preliminary short-term outcomes of a randomized controlled trial of coping skills training (CST) compared with group education (GE) in school-aged children with T1D and their parents. Methods:, One hundred and eleven children (range = 8,12 yr) with T1D for at least 6 months (3.71 ± 2.91 yr) were randomized to CST (55.6% female (F); 81.5% white (W)) or GE (69.7% F; 90.9% W). Children and parents (n = 87) who completed the intervention, baseline, 1- and 3-month data are included. Children completed measures of self-efficacy, coping, and quality of life; parents completed measures of family functioning (adaptability and cohesion), diabetes-related conflict, parent depression, and parent coping. Metabolic control was assessed with glycosylated hemoglobin A1c. Mixed-model repeated measures anova was used to analyze the data. Results:, CST and GE group composition was generally comparable. Children had good psychosocial adaptation and metabolic status. CST parents reported significantly more improvement in family adaptability compared with GE parents, and a trend was seen indicating that CST children showed greater improvement in life satisfaction than GE children. Effect sizes for this short-term follow-up period were small, but group participants were receptive to the intervention and reported positive gains. Conclusions:, In these preliminary results, CST and GE were more similar than different across multiple measure of psychosocial adaptation, although CST showed promising statistical trends for more adaptive family functioning and greater life satisfaction. Longer term follow-up is underway. [source]

Incidence of Kawasaki disease in Japan: the nationwide surveys of 1999,2002

PEDIATRICS INTERNATIONAL, Issue 4 2006
HIROSHI YANAGAWA
Abstract Objective: The purpose of the present study was to describe the results of nationwide epidemiologic surveys of Kawasaki disease for the 4 year period 1999,2002. Methods: The design is a retrospective incidence survey. The patients reported in these two surveys are all new patients who were reported during the two study periods (1999,2000 and 2001,2002), although the data were collected retrospectively. A questionnaire was sent to all pediatric departments of hospitals with 100 beds or more throughout Japan, requesting data on patients with Kawasaki disease, such as sex, age, date of first hospital visit, recurrence, and cardiac lesions. Results: The total number of patients reported in the 4 year period 1999,2002 was 32 266 (18 604 male, 13 662 female), with an average annual incidence of 137.7 per 100 000 children younger than 5 years old. The male/female ratio was 1.30. The incidence peaked at 9,11 months of age, and the proportion of patients under 1 year of age was 26%. The monthly distribution had a high peak in January and a gradual increase in summer. Geographically, the high-incidence areas were limited to certain prefectures and moved from year to year. The cardiac lesions at acute stage and cardiac sequelae occurred more in children under 1 year and older than 4 years. Among the principal symptoms, fever persisting ,5 days occurred most commonly, followed by conjunctival congestion, changes in lips and oral cavity, polymorphous exanthema, and changes of extremities. Cervical lymphadenopathy occurred less. Conclusion: More than 32 000 patients with Kawasaki disease during the 4 year period 1999,2002 were reported to the nationwide incidence surveys. The number of patients is steadily increasing despite the decrease of children. The seasonal variation, geographical distribution, and age-specific distribution support the infection theory for the etiology of Kawasaki disease. [source]

Studies on cerebrospinal fluid ionized calcium and magnesium concentrations in convulsive children

PEDIATRICS INTERNATIONAL, Issue 4 2004
Yusaku Miyamoto
AbstractBackground:,The concentrations of ionized calcium (iCa) and ionized magnesium (iMg) were measured in the cerebrospinal fluid (CSF) of convulsive and non-convulsive children, to investigate the relationship between seizure manifestation and CSF iCa and iMg concentrations. Standard concentrations of CSF iCa and iMg were also established. Methods:,CSF samples from 23 patients, ages 0,15 years, with various forms of seizures and 26 age-matched non-convulsive children were collected by lumbar puncture. CSF was obtained anaerobically and the concentrations of CSF iCa and iMg were measured with an electolyte analyzer (Stat Profile Ultra M1, NOVA, USA) immediately after the lumbar puncture. Results:,The concentrations of CSF iCa were significantly higher in non-convulsive children younger than 11 months old compared with children older than 12 months. The concentrations of CSF iMg in non-convulsive children did not differ significantly with aging. The concentrations of CSF iCa in convulsive children did not differ significantly from the concentrations of non-convulsive children. The concentrations of CSF iMg in convulsive children were significantly lower than in non-convulsive children. Conclusion:,These results suggest that seizure manifestation is related to age-dependent changes in iCa and decreased iMg in the developing brain. [source]

Failure of inactivated influenza A vaccine to protect healthy children aged 6,24 months

PEDIATRICS INTERNATIONAL, Issue 2 2004
Taro Maeda
AbstractBackground:,The efficacy of inactivated influenza vaccine in healthy infants and children younger than 24 months has not been confirmed. The aim of the present study was to determine the prophylactic effect of inactivated influenza vaccine against influenza A in healthy children aged 6,24 months. Methods:,Healthy infants and young children (6,24 months old) were immunized by subcutaneous injection of inactivated influenza vaccine before influenza seasons. Age matched children were randomly assigned as the control. These children were followed up from January to April in each year (2000, 2001 and 2002). The attack rates of influenza A infection was compared and statistically assessed. Results:,The attack rate of influenza A virus infection in the vaccine group and the control group were 14.8% (n = 27) vs 12.5% (n = 32) in 2000 (P = 0.526); 2.8% (n = 72) vs 7.2% (n = 69) in 2001 (P = 0.203); and 3.4% (n = 52) vs 8.9% (n = 56) in 2002 (P = 0.205). The attack rates of influenza A between the two groups were not significantly different. Conclusion:,Inactivated influenza vaccine did not reduce the attack rate of influenza A infection in 6,24 month old children. [source]

Unplanned extubation in a paediatric intensive care unit: impact of a quality improvement programme

ANAESTHESIA, Issue 11 2008
P. S. L. Da Silva
Summary Unplanned tracheal extubation is an important quality issue in current medical practice as it is a common occurrence in paediatric intensive care units. We have assessed the effectiveness of a continuous quality improvement programme in reducing the incidence of unplanned extubation over a 5-year period. After a 2-year baseline period, we developed action plans to address the issues identified. Following implementation of the programme, the overall incidence of unplanned extubation decreased from 2.9 unplanned extubations per 100 intubated patient days in the first year to 0.6 in the last year (p = 0.0001). This reduction was the result of a decrease in unplanned extubation in children younger than 2 years of age. Although mortality was similar to that of children who did not experience an unplanned extubation, those with an unplanned extubation had a significantly longer duration of mechanical ventilation, longer stay in the intensive care unit, and longer hospital stay. We found that the implementation of a continuous quality improvement programme is effective in reducing the overall incidence of unplanned extubations. [source]

REVIEW OF THE EXTENT TO WHICH ORCHIDOPEXY IS PERFORMED AT THE OPTIMAL AGE: IMPLICATIONS FOR HEALTH SERVICES

ANZ JOURNAL OF SURGERY, Issue 11 2008
Christine J. P. Bruijnen
Background: In recent decades, the recommended age for orchidopexy for primary undescended testes has decreased, in the expectation that this might improve subsequent fertility. The aim of this study was to investigate whether this is reflected in a reduction in the age at which orchidopexies are carried out, and the implications for child health services. Methods: All boys who underwent an orchidopexy for an undescended testis carried out by the Christchurch-based paediatric surgical service between January 1997 and December 2007 were identified through a prospectively collected database. They were analysed according to the age at time of operation and year of surgery to determine whether there was any trend over time. The proportions of children younger than 2 years and between 2 and 5 years of age were calculated for each year. Results: In total, 788 boys underwent orchidopexies for primary undescended testes, with 335 (42.5%) boys having surgery before the age of 2 (mean age 54.3 months, median 31.1 months). During the whole 11-year period, there was no significant change in age at orchidopexy, whereas from 2003, a significant trend towards lower age at operation (Spearman's rank ,0.1112, P = 0.0071) and a significant increase in the proportion of boys having surgery before the age of 2 (Spearman's rank 0.9000, P = 0.0374) were seen. Conclusions: Although there has been a modest reduction in the mean age of orchidopexy since 2003, overall, the mean age at orchidopexy remains well above the recommended optimal age, implying that more attention should be paid towards earlier diagnosis and referral for primary undescended testes.

Thalidomide dramatically improves the symptoms of early-onset Sarcoidosis/Blau syndrome: Its possible action and mechanism

ARTHRITIS & RHEUMATISM, Issue 1 2010
Kozo Yasui
Objective Early-onset sarcoidosis (EOS), which occurs in children younger than 5 years of age, is associated with granulomatous lesions and a sporadic genetic mutation of the nucleotide-binding oligomerization domain 2 that causes constitutive NF-,B activation. The symptoms of EOS can be uncontrollable, progressive, and associated with profound complications. However, appropriate therapy is still under investigation. The aim of this study was to assess the efficacy of thalidomide in patients with severe EOS, based on etiology supporting an initial role of NF-,B in activation of this disease. Methods Thalidomide was given to 2 patients with EOS (a 16-year-old girl and an 8-year-old boy) at an initial dosage of 2 mg/kg/day, and the dosage was increased if necessary. To elucidate the mechanism of the drug, peripheral blood monocytes were isolated from the patients and stimulated with cytokines (macrophage colony-stimulating factor, tumor necrosis factor ,, and interleukin-4), and their ability to form multinucleated giant cells (MGCs) and osteoclasts was measured. Results Both patients showed dramatic improvement of their clinical symptoms (alleviation of fever and optic nerve papillitis, achievement of a response according to the American College of Rheumatology Pediatric 50 and Pediatric 70 criteria) and laboratory findings. Monocytes from patients with EOS had a greater ability to survive and induce MGCs and osteoclasts than those from healthy control subjects. The formation of MGCs and osteoclasts was inhibited by the presence of thalidomide. Conclusion The ability of thalidomide to improve clinical symptoms and laboratory findings in patients with EOS indicates a central role for NF-,B activity in this disorder. Inhibition of IKK might be a pharmacologic action by which thalidomide down-regulates NF-,B signaling. Thalidomide may be an effective medication in patients with severe complications of EOS, including ocular involvement. [source]

Interobserver Agreement in Assessment of Clinical Variables in Children with Blunt Head Trauma

ACADEMIC EMERGENCY MEDICINE, Issue 9 2008
Marc H. Gorelick MD
Abstract Objectives:, To be useful in development of clinical decision rules, clinical variables must demonstrate acceptable agreement when assessed by different observers. The objective was to determine the interobserver agreement in the assessment of historical and physical examination findings of children undergoing emergency department (ED) evaluation for blunt head trauma. Methods:, This was a prospective cohort study of children younger than 18 years evaluated for blunt head trauma at one of 25 EDs in the Pediatric Emergency Care Applied Research Network (PECARN). Patients were excluded if injury occurred more than 24 hours prior to evaluation, if neuroimaging was obtained at another hospital prior to evaluation, or if the patient had a clinically trivial mechanism of injury. Two clinicians independently completed a standardized clinical assessment on a templated data form. Assessments were performed within 60 minutes of each other and prior to clinician review of any neuroimaging (if obtained). Agreement between the two observers beyond that expected by chance was calculated for each clinical variable, using the kappa (,) statistic for categorical variables and weighted kappa for ordinal variables. Variables with a lower 95% confidence limit (LCL) of , > 0.4 were considered to have acceptable agreement. Results:, Fifteen-hundred pairs of observations were obtained. Acceptable agreement was achieved in 27 of the 32 variables studied (84%). Mechanism of injury (low, medium, or high risk) had , = 0.83. For subjective symptoms, kappa ranged from 0.47 (dizziness) to 0.93 (frequency of vomiting); all had 95% LCL > 0.4. Of the physical examination findings, kappa ranged from 0.22 (agitated) to 0.89 (Glasgow Coma Scale [GCS] score). The 95% LCL for kappa was <0.4 for four individual signs of altered mental status and for quality (i.e., boggy or firm) of scalp hematoma if present. Conclusions:, Both subjective and objective clinical variables in children with blunt head trauma can be assessed by different observers with acceptable agreement, making these variables suitable candidates for clinical decision rules.

Childhood epidermolysis bullosa acquisita with autoantibodies against the noncollagenous 1 and 2 domains of type VII collagen: case report and review of the literature

BRITISH JOURNAL OF DERMATOLOGY, Issue 5 2006
M. Mayuzumi
Summary Epidermolysis bullosa acquisita (EBA) is an acquired subepidermal bullous disease characterized by IgG autoantibodies to type VII collagen, a major component of anchoring fibrils. Most patients with EBA are adult and develop autoantibodies to the noncollagenous (NC) 1 domain of type VII collagen. We describe a 4-year-old Japanese boy presenting pruritic vesicles and tense blisters over his whole body. Immunofluorescence studies revealed linear IgG/C3 deposits along the dermal,epidermal junction of the patient's skin, and circulating IgG autoantibodies mapping to the dermal side of 1 M NaCl-split skin. By immunoblotting analysis using dermal extracts as a substrate, the patient's IgG antibodies labelled a 290-kDa protein corresponding to type VII collagen. Immunoblotting studies using recombinant proteins demonstrated that the patient's circulating autoantibodies recognized not only the NC1 but also the NC2 domain of type VII procollagen. Review of the previously reported cases and the present case suggested that patients with EBA with autoantibodies to regions other than the NC1 domain are all children younger than 10 years of age with clinical features of an inflammatory phenotype.

In utero exposure to female hormones and germ cell tumors in children,

CANCER, Issue 5 2006

Abstract BACKGROUND Maternal exposure to exogenous female hormones during pregnancy has been implicated as a risk factor for malignant germ cell tumors (GCTs) in the offspring in some epidemiologic studies of testicular and ovarian carcinoma in adults. METHODS From 1996 to 2002, 278 children younger than 15 years of age with malignant GCTs and 423 healthy controls, frequency-matched for geographic location, age, and sex were enrolled in a case,control study to investigate whether in utero exposure to female hormones is associated with the risk of malignant GCT in children. Cases were recruited from 84 institutions in the U.S. and controls were enrolled through random digit dialing. Information was obtained through telephone interview with the biological mothers of the subjects and through blinded review of the mothers' medical records. RESULTS Neither self-reported (odds ratio [OR] = 1.15; 95% confidence interval [CI], 0.63, 2.12) nor medical chart based (OR = 1.14; 95% CI, 0.75, 1.73) maternal exposure to exogenous female hormones was related to malignant GCT risk. Pregnancy-related conditions that may have altered serum levels of circulating female hormones were also unrelated to the risk of GCT in the offspring. CONCLUSION This study failed to provide strong evidence to support the hypothesis that maternal exposure to exogenous female hormones during pregnancy increases the risk of GCT in the offspring.

Nevoid basal cell carcinoma syndrome: Relation with desmoplastic medulloblastoma in infancy

CANCER, Issue 3 2003
A population-based study, review of the literature
Abstract BACKGROUND Patients with nevoid basal cell carcinoma syndrome (NBCCS) are believed to be predisposed to develop early-onset neoplasms including medulloblastomas (MB). The desmoplastic subtype of MB is associated most commonly with NBCCS. The goals of this study were to demonstrate the relation between desmoplastic MB and NBCCS and to evaluate the concomitant diagnosis of NBCCS and MB. METHODS The medical records of 76 consecutive children who received surgical treatment for MB between 1970 and 2000 were studied. A review of the literature was performed based on the National Library of Medicine database and bibliographies of selected articles were scanned. RESULTS The authors reported three patients with NBCCS who received surgical treatment for an MB during infancy. The literature review identified 33 patients with NBCCS who were treated for MB at a mean age of 28 months. The desmoplastic subtype was the only histopathologic subtype of MB reported in the NBCCS population. Although patients with NBCCS are predisposed to develop multiple basal cell carcinomas and intracranial tumors in the field of irradiation, the prognosis for syndromic MBs was much better compared with the prognosis for sporadic MBs. CONCLUSIONS Patients with NBCCS have an increased risk for other malignancies, especially radiation-induced neoplasms. Early diagnosis of this syndrome is important for the selection of appropriate adjuvant treatment and family genetic counseling. The authors did not advocate the use of radiotherapy as an adjuvant treatment in desmoplastic MB diagnosed in children younger than 5 years of age. They suggested that the desmoplastic subtype of MB in children younger than 2 years of age is a major diagnostic criterion for the diagnosis of NBCCS.

Suicidal Behavior in Children Younger than Twelve: A Diagnostic Challenge for Emergency Department Personnel

Invasive pneumococcal disease in children prior to implementation of the conjugate vaccine in the Zurich region, Switzerland

ACTA PAEDIATRICA, Issue 7 2010
P Gessler
Abstract Objective:, To describe symptoms, disease manifestations and outcome of invasive pneumococcal disease in children prior to implementation of the pneumococcal vaccine. Patients and methods:, Analysis of children younger than 16 years of age with invasive pneumococcal disease (IPD; n = 119). Children with culture-confirmed IPD, without underlying illness at risk for invasive disease, were included. Results:, IPD in 90 children (age: median 2, mean 3.2 years) included 15 with meningitis, 16 with septicaemia, 14 with bacteraemia, 24 with pneumonia and 21 with skin, bone and joint infections. Symptoms of IPD most often described were fever and gastrointestinal symptoms (abdominal pain, vomiting, or diarrhoea), and coughing. More than 90% of children with pneumonia were coughing. Most importantly, clinical signs significantly predictive for severe IPD included tachycardia for sepsis, tachypnea for pneumonia, and meningeal signs for meningitis. Leukocyte, neutrophil and platelet counts were lower and C-reactive protein concentrations were higher on admission in children with complicated than in children with uncomplicated IPD but, due to wide overlap of these numbers, the difference was not of prognostic help to predict clinical course and outcome. Overall, 40% of children with IPD manifested complications and IPD showed a mortality rate of 6.6%. Conclusions:, IPD is a serious disease with a high complication rate and mortality. The clinical signs tachycardia, tachypnea, and meningism were highly predictive for severe IPD. The initial clinical presentation and laboratory evaluation were mostly unpredictable with respect to complications and outcome in contrast to the clinical signs. [source]

Montelukast does not prevent reactive airway disease in young children hospitalized for RSV bronchiolitis

ACTA PAEDIATRICA, Issue 11 2009
M Proesmans
Abstract Aim:, To evaluate the long-term effect of montelukast on symptoms of cough and wheeze following RSV bronchiolitis. Methods:, Fifty eight patients (aged , 24 months) hospitalized with a first episode of RSV bronchiolitis were enrolled in this double blind prospective randomized trial comparing montelukast (n = 31) vs placebo (n = 27). Results:, During the 3-month treatment period, there were no statistical significant differences between the two groups for symptom-free days and nights (48.5 [interquartile range 33.0.0,66.0] for montelukast vs 57.0 [29.0,71.0] for placebo p = 0.415) nor disease-free days and nights (44.5 days [26.0,54.0] vs 53.0 [22.3,71.0]; p = 0.266). During the 1 year follow-up, there were 41 exacerbations in the montelukast group vs 54 exacerbations in the placebo group (p = 0.57). Time to first exacerbation was not different. Number of unscheduled visits and need to start inhaled steroids were comparable in the two groups. Conclusion:, Treatment with montelukast after hospital admission for RSV bronchiolitis in children younger than 2 years of age did not reduce symptoms of cough and wheeze. We cannot exclude that a subgroup of children may, however, benefit from this treatment. [source]

A Pilot Study of Ultrasound Analysis before Pediatric Peripheral Vein Cannulation Attempt

ACADEMIC EMERGENCY MEDICINE, Issue 5 2007
David Schnadower MD
ObjectivesTo determine whether peripheral veins can be detected by ultrasound (US) and to determine vein characteristics, as measured by US, that are associated with successful peripheral venous (PV) catheterization in young children. MethodsThe authors conducted an observational study in the pediatric emergency department (ED), with a convenience sample of children younger than 7 years. They evaluated attempts at PV catheterization in two groups on the basis of the visibility and palpability of the patients' veins: 1) clinically apparent (visible or palpable) and 2) not clinically apparent (nonvisible and nonpalpable). The authors obtained sonographic measurements in a transverse view (vertical diameter, circumference, and area) and in a longitudinal view (maximal uninterrupted length). Practitioners blinded to the US images then attempted to catheterize veins in the usual manner. The proportion of clinically apparent veins and the proportion of veins that were successfully catheterized that were identified by US were assessed, and the association between ultrasonographic vein measurements and success at catheterization, controlling for possible confounders, was determined. ResultsThe authors assessed 120 attempts (90 clinically apparent and 30 not clinically apparent) at PV catheterization in 83 patients. US detected all 90 clinically apparent veins, and cannulation success rate was 62/90 (69%). In the not clinically apparent vein group, the rate of success was only 3/30 (10%), and US detected all successfully catheterized veins. In no instance was cannulation successful when the vein was not detected by US. Maximal vein length in longitudinal view was an independent predictor of cannulation success in multivariate analysis. ConclusionsUltrasound appears to be capable of detecting peripheral veins in children younger than 7 years of age, with lack of US vein visualization likely leading to unsuccessful PV placement. Greater vein length visualization may be a useful predictor of successful PV catheterization. [source]

Oral health inequalities between young Aboriginal and non-Aboriginal children living in Ontario, Canada

Abstract,,, Objectives:, To investigate (i) oral health inequalities between off-reserve Aboriginal and non-Aboriginal children entering junior kindergarten (JK) in the Thunder Bay District, Northwest Ontario, Canada, (ii) oral health inequalities between kindergarten-aged (4 years old) Aboriginal children living on reserves in the Sioux Lookout Zone (SLZ), Northwest Ontario and those living off-reserve in the Thunder Bay District and (iii) early childhood caries (ECC) trends among SLZ children between 2001 and 2005. Methods:, Cross-sectional oral health data (dmft/s Indices) for 416 (2003/2004), 687 (2004/2005) and 544 (2005/2006) 3- to 5-year olds attending JK in the Thunder Bay District were collected by calibrated dental hygienists with the District's Health Unit. Secondary analysis of oral health status data from two studies conducted in the SLZ between 2001 and 2005 provided the dmft of random samples of children younger than 6 years of age living in 16,20 First Nations communities. Results:, When compared with non-Aboriginal children aged 3,5 years attending the same schools in the Thunder Bay District between 2003 and 2006, off-reserve Aboriginal children had 1.9 to 2.3 times the risk of having ECC (dmft > 0), 2.9 to 3.5 times the risk of a dmft > 3 and 1.8 to 2.5 times the risk of untreated decayed teeth after adjusting the prevalence ratios for child's age and sex, school's risk level and clustered-correlated data. The mean dmft of on-reserve Aboriginal 4-year olds in 2005 was 11.2 and 5.9 for their off-reserve Aboriginal counterparts. In 2001, the mean dmft scores (95% confidence interval) of 2-, 3- and 4-year-old Aboriginal children in the SLZ were: 9.1 (8.3,9.9), 12.4 (11.8,13.1), 13.1 (12.1,14.2). In 2005, similarly aged SLZ children had a mean dmft of: 6.2 (5.2,7.1), 8.9 (8.2,9.6), 11.2 (10.5,11.9), representing significant reductions in caries severity (32%, 28% and 14.5%, respectively). Conclusions:, Significant disparities in caries experience exist between off-reserve Aboriginal and non-Aboriginal children living in the same locales and between Aboriginal children living on- and off-reserve in northwestern Ontario. The study showed decreased trends in the severity of ECC for children in the SLZ occurring over the 5-year period. Despite this progress, the oral health of young Aboriginal children in Ontario continues to lag far behind that of non-Aboriginal children, demanding further programs and policies to tackle the social determinants of oral health and resolve these inequalities.

Total fluoride intake in children aged 22,35 months in four Colombian cities

COMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 1 2005
Ángela M. Franco
Abstract , Objective: To obtain information on the level of total fluoride intake from food, beverages and toothpaste by children at the age of 22,25 months of low and high socioeconomic status (SES) in major Colombian cities. Methods:, Daily fluoride intake was assessed by the duplicate plate method and by recovered toothpaste solution during a 3-day period and afterwards analysed by the microdiffusion method. Results:, Mean daily fluoride intake was 0.11 (±0.10), 0.14 (±0.12), 0.10 (±0.07) and 0.07 (±0.06) mg/kg body weight (bw)/day in Bogotá, Medellín, Manizales and Cartagena, respectively. The total fluoride intake was higher in low-SES subjects in the cities of Medellín and Bogotá. In the high-SES children of the four cities, the average intakes ranged from 0.06 to 0.09 mg F/kg bw, whereas, the low-SES children in three cities had intakes between 0.11 and 0.21 mg F/kg bw (Cartagena, 0.07). Toothpaste (containing 1000,1500 ppm F, with 1500 ppm F being more common) accounted for approximately 70% of total fluoride intake, followed by food (24%) and beverages (<6%). More than half the children had their teeth brushed by an adult, on average twice a day, using 0.22,0.65 g of toothpaste. Conclusion:, Children from three Colombian cities have a mean total daily fluoride intake above the ,optimal range'. Health authorities should promote an appropriate use of fluoridated dentifrices discouraging the use of dentifrices containing 1500 ppm F in children younger than 6 years of age and promoting a campaign of education of parents and oral health professionals on adequate toothbrushing practices.
