The Type of Anesthesia Used during Cesarean Section Is Related to the Transient Tachypnea of the Newborn

Wed, 24 Apr 2013 13:43:14 +0000

Aim. To demonstrate whether transient tachypnea of the newborn (TTN) is found more frequently in women undergoing general or combined epidural-spinal (CES) anesthesia during Cesarean section. Methods. This study was done retrospectively. A total of 1447 Cesarean sections (C/S) were performed in our clinic between January 2008 and December 2011. General anesthesia was performed in 1078 (74.5%) of the Cesarean cases. CES anesthesia was performed in 369 cases (25.5%). The International Classification of Diseases,Tenth Revision code of P22.1, was used to identify the infants with TTN. Stratified multivariate analysis was undertaken on subgroups to assess the effect modification by factors known to influence the incidence of TTN: maternal age, maternal systolic-diastolic artery pressure, heart rate, Apgar score at 1 and 5 minutes, sex, time interval from spinal block to skin incision, and time interval from skin incision to umbilical cord clamping. Results. The rate of TTN diagnosis was found to be higher in parturients who had a cesarean section with combined epidural-spinal anesthesia, but no statistical differences were found. (odds ratio = 1.471 and 95%CI: 0.92–2.35). Conclusions. The incidence of TTN was found related to C/S but independent from the type of anesthesia. However, studies with a wider spectrum of patients and a lower quantitative difference between the groups are needed in order to draw firm this conclusions.

Heart Rate and Arterial Pressure Changes during Whole-Body Deep Hypothermia

Thu, 11 Apr 2013 16:50:32 +0000

Whole-body deep hypothermia (DH) could be a new therapeutic strategy for asphyxiated newborn. This retrospective study describes how DH modified the heart rate and arterial blood pressure if compared to mild hypothermia (MH). Fourteen in DH and 17 in MH were cooled within the first six hours of life and for the following 72 hours. Hypothermia criteria were gestational age weeks; birth weight g; clinical signs of moderate/severe hypoxic-ischemic encephalopathy. Rewarming was obtained in the following 6–12 hours (0.5°C/h) after cooling. Heart rates were the same between the two groups; there was statistically significant difference at the beginning of hypothermia and during rewarming. Three babies in the DH group and 2 in the MH group showed HR < 80 bpm and QTc > 520 ms. Infant submitted to deep hypothermia had not bradycardia or Qtc elongation before cooling and after rewarming. Blood pressure was significantly lower in DH compared to MH during the cooling, and peculiar was the hypotension during rewarming in DH group. Conclusion. The deeper hypothermia is a safe and feasible, only if it is performed by a well-trained team. DH should only be associated with a clinical trial and prospective randomized trials to validate its use.

Prevalence and Clinical and Immunoviralogical Profile of Human Immunodeficiency Virus-Hepatitis B Coinfection among Children in an Antiretroviral Therapy Programme in Benue State, Nigeria

Emmanuel Ademola Anigilaje and Ayodotun Olutola — Wed, 03 Apr 2013 11:26:37 +0000

Background. Nigeria has the world largest burden of paediatric HIV and is also highly endemic for Hepatitis B virus (HBV). However, relatively little is known regarding the prevalence of HBV-HIV coinfections among Nigerian children. Methods. A retrospective study among treatment naive HIV-infected children attending the pediatric clinic of the APIN Plus/Harvard PEPFAR program of the Federal Medical Centre, Makurdi, between June 2008 and June 2012. Results. The mean age of the 395 subjects studied was years. Thirty-one subjects (7.8%) were positive for HBV. No subject was HIV-HBV-HCV triply infected. Significantly higher HIV-HBC coinfections were found, in older subjects (11–15 years), subjects that did not receive nor complete Hepatitis B vaccinations, and subjects that had a severe immunosuppression of < 15% with respective values of 0.00, 0.01, and 0.00. HIV-HBV co-infection did not significantly impact on other baseline characteristics including, gender, WHO clinical stage, median absolute CD4 count, mean viral load, median ALT, and hepatotoxicity. Conclusion. A high seroprevalence of HBV among this cohort of HIV-infected children contributes to the calls for pre-ART screening for HBV and the necessary paradigm shift in the ART nucleoside backbone to include agent(s) more dually effective against HIV and HBV.

Clinical Asthma Phenotypes and Therapeutic Responses

Sun, 31 Mar 2013 11:26:56 +0000

Asthma is a heterogeneous disease that means not all asthmatics respond to the same treatment. We hypothesize an approach to characterize asthma phenotypes based on symptomatology (shortness of breath (SOB), cough, and wheezy phenotypes) in correlation with airway inflammatory biomarkers and FEV1. We aimed to detect whether those clinical phenotypes have an impact on the response to asthma medications. Two hundred three asthmatic children were allocated randomly to receive either montelukast (5 mg at bed time) or fluticasone propionate (100 ug twice daily) for 8 consecutive weeks. Serum concentrations of IL-2Rs, ICAM-1, VCAM-1, total IgE, eosinophilic %, eosinophil cationic protein (ECP), and FEV1 were done before and after treatment to patients and once to controls. Children who have SOB were found to have higher levels of total sIgE, older age, and longer disease duration, and they responded to fluticasone alone. Cough group was found to have higher levels of eosinophilic % and sECP, younger age, shorter disease duration and responded to montelukast alone. Wheezy group showed mixed pattern and responded to both medications. Conclusion. Although there is variability in response to ICS and LTRAs, we did identify characteristics of patient that should guide the clinician in the choice of asthma medications.

Automatic Tube Compensation versus Pressure Support Ventilation and Extubation Outcome in Children: A Randomized Controlled Study

Tue, 26 Feb 2013 10:13:47 +0000

Background. Automatic tube compensation (ATC) has been developed to overcome the imposed work of breathing due to artificial airways during spontaneous breathing trials (SBTs). Objectives. This study aimed to assess extubation outcome after an SBT (spontaneous breathing trial) with ATC compared with pressure support ventilation (PSV) and to determine the risk factors for extubation failure. Methods. Patients ready for extubation were randomly assigned to two-hour spontaneous breathing trial with either ATC or pressure support ventilation. Results. In the ATC group (), 11 (65%) patients passed the SBT with subsequent extubation failure (9%). While in PSV group (), 10 (53%) patients passed the SBT with subsequent extubation failure (10%). This represented a positive predictive value for ATC of 91% and PSV of 90% (). Five (83%) of the patients who failed the SBT in ATC group were reintubated. This represented a higher negative predictive value for ATC of 83% than for PSV which was 56%. None of the assessed risk factors were independently associated with extubation failure including failed trial. Conclusion. ATC was equivalent to PSV in predicting patients with successful extubation. A trial failure in ATC group is associated with but does not definitely predict extubation failure.

To Evaluate Serum Eosinophil Cationic Protein and Total IgE Concomitantly May Predict the Persistence of Wheezing in Young Children

Esengül Keleş, Hamza Yazgan, and Arzu Gebeşçe — Mon, 24 Dec 2012 10:45:27 +0000

Background. We investigated the predictive value and the relative risk of the evaluation of serum eosinophilic cationic protein (sECP) and total IgE levels concomitantly in relation to the persistence of wheezing in young children. Methods. The study was conducted prospectively between January 2007 and December 2010. A hundred and eight children, aged between three months and four years, with three or more episodes of wheezing, were studied to evaluate the role of eosinophil inflammation and its relation to persistence of wheezing two years later. Results. A statistically significant difference in terms of total IgE and sECP values was observed between the groups (). When measurement of IgE and sECP was assessed concomitantly, the sensitivity was found to be 92.68%, the negative predictive value was found to be 71.43%, accuracy rate was found to be 84.26%, and the relative risk was found to be 3.06 in group 1. Conclusions. In this study, we aimed to emphasize the importance of the assessment of sECP and total IgE concomitantly, as being two noninvasive and easily applicable tests, useful in predicting persistent wheezing in early childhood.

Peer-Mediated Multimodal Intervention Program for the Treatment of Children with ADHD in India: One-Year Followup

Thu, 20 Dec 2012 13:48:10 +0000

The objective was to assess the efficacy of a one-year, peer-mediated interventional program consisting of yoga, meditation and play therapy maintained by student volunteers in a school in India. The population consisted of 69 students between the ages of 6 and 11 years, previously identified as having attention deficit hyperactivity disorder (ADHD). A program, known as Climb-Up, was initially embedded in the school twice weekly. Local high school student volunteers were then trained to continue to implement the program weekly over the period of one year. Improvements in ADHD symptoms and academic performance were assessed using Vanderbilt questionnaires completed by both parents and teachers. The performance impairment scores for ADHD students assessed by teachers improved by 6 weeks and were sustained through 12 months in 46 (85%) of the enrolled students. The improvements in their Vanderbilt scores assessed by parents were also seen in 92% (, Wilcoxon). The Climb-Up program resulted in remarkable improvements in the students’ school performances that were sustained throughout the year. These results show promise for a cost-effective program that could easily be implemented in any school.

Diabetic and Metabolic Programming: Mechanisms Altering the Intrauterine Milieu

Claudia Eberle and Christoph Ament — Tue, 20 Nov 2012 14:57:25 +0000

A wealth of epidemiological, clinical, and experimental studies have been linked to poor intrauterine conditions as well as metabolic and associated cardiovascular changes postnatal. These are novel perspectives connecting the altered intrauterine milieu to a rising number of metabolic diseases, such as diabetes, obesity, and hypercholesterolemia as well as the Metabolic Syndrome (Met S). Moreover, metabolic associated atherosclerotic diseases are connected to perigestational maternal health. The “Thrifty Phenotype Hypothesis” introduced cross-generational links between poor conditions during gestation and metabolic as well as cardiovascular alterations postnatal. Still, mechanisms altering the intrauterine milieu causing metabolic and associated atherosclerotic diseases are currently poorly understood. This paper will give novel insights in fundamental concepts connected to specific molecular mechanisms “programming” diabetes and associated metabolic as well as cardiovascular diseases.

Childhood Convulsion: Inquiry about the Concerns and Home Management among Mothers in Tegbesun, a Periurban Community in Ilorin, Nigeria

Emmanuel Ademola Anigilaje and Omolara Olufunmilayo Anigilaje — Tue, 20 Nov 2012 12:08:54 +0000

Background. The fear and panic felt by most parents when their child convulsed made them apply all sorts of management. Objective. This study evaluated the concerns and home management of childhood convulsions among mothers in Tegbesun, a periurban community in Ilorin, Nigeria. Methods. A ten-week cross-sectional study comprising 500 mothers interviewed using a structured questionnaire. Results. Fear of death was the commonest concern (450, 90%) among mothers. For a witnessed convulsion, the majority took the child to the hospital (414, 82.8%). Cow’s urine concoction (74, 87.1%) was the most common item administered to a convulsing child. Putting the hand and/or a spoon into the mouth of the convulsing child was the commonest unwholesome practice (74, 61.2%). None of the subjects safely put the convulsing child on his/her side. Conclusions. Maternal concerns are precursors of mismanagement of childhood convulsions, and health education was undertaken at the end of the study.

High Neonatal Mortality Rates in Rural India: What Options to Explore?

Sun, 18 Nov 2012 09:59:12 +0000

The neonatal mortality rate in India is amongst the highest in the world and skewed towards rural areas. Nonavailability of trained manpower along with poor healthcare infrastructure is one of the major hurdles in ensuring quality neonatal care. We reviewed case studies and relevant literature from low and middle income countries and documented alternative strategies that have proved to be favourable in improving neonatal health. The authors reiterate the fact that recruiting and retaining trained manpower in rural areas by all means is essential to improve the quality of neonatal care services. Besides this, other strategies such as training of local rural healthcare providers and traditional midwives, promoting home-based newborn care, and creating community awareness and mobilization also hold enough potential to influence the neonatal health positively and efforts should be made to implement them on a larger scale. More research is demanded for innovations such as “m-health” and public-private partnerships as they have been shown to offer potential in terms of improving the standards of care. The above proposed strategy is likely to reduce morbidity among neonatal survivors as well.

QTc and QTd in Children with Type 1 Diabetes Mellitus during Diabetic Ketoacidosis

Omneya I. Youssef and Samar M. Farid — Tue, 06 Nov 2012 08:37:40 +0000

Cardiac arrest has been described in children with diabetic ketoacidosis (DKA). Aim. To evaluate QTc and QTd in type 1 diabetic children with DKA. Methods. Twelve-lead ECG was done to 30 type 1 diabetic children with DKA at presentation and recovery. Corrected QT interval and QT dispersion (QTd) were assessed. Results. QTc and QTd mean values were significantly decreased in patients after than before DKA recovery (). Procedure. Sixteen patients (53, 3%) had prolonged QTc during DKA (range 451–538 ms) that dropped to one patient after recovery, his QTc (453 ms) returned to normal 5 days after hospital discharge. Nineteen patients (63.3%) had prolonged QTd (>50 ms) that dropped to three after recovery. The fact that three patients had normal QTc but prolonged QTd increases the privilege of QTd over QTc as a better marker for cardiac risk in those patients. Anion gap was significantly associated with QTc and QTd prolongation (). Patients had no electrolyte abnormalities or hypoglycemia to account for QTc or QTd prolongation. Conclusion. Prolonged QTc and QTd frequently occur in DKA positively correlated to ketosis. Cardiac monitoring for patients with DKA is mandatory.

Primary Closure without Diversion in Management of Operative Blunt Duodenal Trauma in Children

Mon, 05 Nov 2012 09:34:19 +0000

Background. Operative blunt duodenal trauma is rare in pediatric patients. Management is controversial with some recommending pyloric exclusion for complex cases. We hypothesized that primary closure without diversion may be safe even in complex (Grade II-III) injuries. Methods. A retrospective review of the American College of Surgeons’ Trauma Center database for the years 2003–2011 was performed to identify operative blunt duodenal trauma at our Level 1 Pediatric Trauma Center. Inclusion criteria included ages years and duodenal injury requiring operative intervention. Duodenal hematomas not requiring intervention and other small bowel injuries were excluded. Results. A total of 3,283 hospital records were reviewed. Forty patients with operative hollow viscous injuries and seven with operative duodenal injuries were identified. The mean Injury Severity Score was 10.4, with injuries ranging from Grades I–IV and involving all duodenal segments. All injuries were closed primarily with drain placement and assessed for leakage via fluoroscopy between postoperative days 4 and 6. The average length of stay was 11 days; average time to full feeds was 7 days. No complications were encountered. Conclusion. Blunt abdominal trauma is an uncommon mechanism of pediatric duodenal injuries. Primary repair with drain placement is safe even in more complex injuries.

Risk Factors of Antibiotic Misuse for Upper Respiratory Tract Infections in Children: Results from a Cross-Sectional Knowledge-Attitude-Practice Study in Greece

Thu, 01 Nov 2012 12:47:12 +0000

Background. Upper respiratory tract infections (URTIs) are common in children. The cause of URTIs is usually viral, but parents’ attitudes often contribute to inappropriate prescription of antibiotics, promoting antibiotic resistance. The objective of this study was to identify possible risk factors associated with antibiotic misuse in Greece, a country with high levels of antibiotic use and antibiotic resistance. Methods. A knowledge-attitude-practice (KAP) questionnaire was developed and distributed to Greek parents caring for children who were 5-6 years old, between January and July of the same school year. Results. The sample of the study contained 5312 parents from all geographic areas of Greece. The risk factors of being a father, having low education, having immigrant status, being a single parent, having low income, having <2 or >3 children, living in the islands, and being without experience in recurrent URTIs were significantly associated to inadequate knowledge, inappropriate attitudes, and wrong practices. Conclusions. This study has identified the main groups of parents that should be targeted in future intervention programs.

Therapeutic Role of Mobilized Bone Marrow Cells in Children with Nonischemic Dilated Cardiomyopathy

Nevin M. Habeeb, Omneya I. Youssef, and Eman S. El Hadidi — Sun, 21 Oct 2012 12:03:12 +0000

Dilated cardiomyopathy is an important cause of congestive cardiac failure in infants and children. Mobilizing hematopoietic progenitor cells is a promising intervention to this deadly disease. Aim. Evaluate granulocyte colony stimulating factor (GCSF) as therapeutic modality in children with idiopathic dilated cardiomyopathy (IDCM). Subjects and Methods. This case-control prospective study was conducted on 20 children with IDCM following up at Cardiology Clinic Children's Hospital, Ain Shams University (group 1) who were compared to another 10 age-, sex-, duration-of-illness-, and systolic-function-matched children with IDCM as control (group 2). They were subjected to history taking, clinical examination, echocardiography, and peripheral blood CD34+ cell assessment before and one week after GCSF intake for 5 consecutive days (by group 1 but not group 2). Results. A significant improvement in echocardiographic data and CD34+-T-cell increase was found in group 1 one week after GCSF intake and for the next 6 months CD34+ T cells percentage of change showed no significant correlation with the that of the left ventricular dimensions and systolic function. Conclusion. Administration of GCSF to children with IDCM resulted in clinical and echocardiographic improvement not correlated to mobilized CD34+ T cells, implying involvement of additional mechanisms over simple stem cell mobilization.

Prevalence of Toxoplasma Infection in Mexican Newborns and Children: A Systematic Review from 1954 to 2009

Tue, 25 Sep 2012 12:14:08 +0000

Introduction. Recent studies in Mexico have shown that from 20/10,000 to 58/10,000 newborns with Toxoplasma infection could be undetected. The aim of this study was to determine the weighed prevalence of T. gondii infection and describe the epidemiological transition of infection in newborns. Methods. Research literature reporting Toxoplasma infection prevalence in Mexican newborns and children were searched in five international databases. Weighted prevalence was calculated by inverse variance-weighted method in asymptomatic and symptomatic study groups, and the epidemiological transition was estimated by a lineal regression analysis. Results. The weighed prevalence in 4833 asymptomatic newborns was 0.616%, CI95% (0.396%–0.835%) (), whereas, among 895 symptomatic newborns, the weighed prevalence was 3.02%, CI 95% (1.91%–4.1%) (). A downward trend of 0.25%/year represented an accumulated decrease of −13,75% in the prevalence in the symptomatic newborns throughout 55 years, whereas, in the asymptomatic children, the prevalence was similar over the course of the years. Conclusion. The high-weighted prevalence of congenital Toxoplasma infection in newborns justifies that Toxoplasma gondii testing be included in the screening programs for women during pregnancy and newborns in Mexico. A rapid diagnosis and treatment strategy could aid in limiting a potential damage to the newborns.

Validation of Advanced Paediatric Life Support Formulas for Weight Calculation in a Multiethnic Population

Colette Seddon, Laurell Lockitt, Sacha Dhanjal, and Michael Eisenhut — Tue, 25 Sep 2012 11:59:34 +0000

Introduction. The aims of this study were to validate the new formulas for weight calculation introduced by the advanced life support group (alsg) of the United Kingdom in 2011 and compare their performance to the formula currently used by the European Resuscitation Council (ERC) and other formulas and to check whether performance of formulas for weight calculation is affected by ethnic group and gender. Methods. Prospective audit of weight versus calculated weight comparing alsg formula with ERC, Luscombe, Argall, and Best Guess formulas analysed for gender, age, and ethnic groups. Results. Prospectively 599 children were included: 157 Asian, 268 Caucasian, and 174 children from other origin. In infants there was no difference between actual weight and alsg formula calculated weight. There was a progressively increased underestimation of weight year by year from 1 to 10 years of age using the ERC formula. In the 6–10 year age group the ERC formula underestimated the weight by a mean of 6.5 kg (21.8%, ) with the alsg and Luscombe formulas performing best. In 11-12 year old children the alsg formula estimated well. Conclusion. In one- to ten-year-old children, the Luscombe formula provided a better weight estimate than alsg and ERC formulas in a multiethnic population.

Diagnostic Value of Exhaled Carbon Monoxide as an Early Marker of Exacerbation in Children with Chronic Lung Diseases

Karima A. Abd EL Khalek, Magda Y. EL Seify, Omneya I. Youssef, and Mona M. Badr — Tue, 11 Sep 2012 10:44:33 +0000

Chronic airways infection and inflammation are leading causes of morbidity and mortality in chronic lung diseases (CLD). Pulmonary exacerbations are major causes of morbidity in CLD. Exhaled carbon monoxide (eCO) is a product of endogenous metabolic processes whose presence in exhaled breath is considered an index of inflammatory processes. Objective. To evaluate carbon monoxide (eCO) as inflammatory marker for early detection of acute exacerbation in CLD. Methods. Case control study included 40 children with CLD (twenty in exacerbation, group I and twenty in quiescent period, group II) recruited from the Chest Clinic, Children’s Hospital, Ain Shams University. Twenty apparently healthy children were included as controls (group III). Results. Patients’ mean age was 9.98 ± 3.29 years: 24 (60%) males and 16 (40%) females. The mean eCO level among patients during exacerbation was 5.35 ± 1.35 (ppm) compared to 2.65 ± 0.49 (ppm) in quiescent stage and 1.30 ± 0.47 (ppm) in controls. eCO cutoff value discriminating cases and control was 1.5 (ppm) (sensitivity; 100% and specificity 70%) and cutoff value discriminating group I from group II was 3 (ppm) (sensitivity: 100% and specificity: 100%). Conclusion. Exhaled CO can be considered a noninvasive early marker of acute exacerbation of CLD.

Cow’s Milk Allergy Is a Major Contributor in Recurrent Perianal Dermatitis of Infants

Mon, 03 Sep 2012 11:52:57 +0000

Background. Recurrent perianal inflammation has great etiologic diversity. A possible cause is cow’s milk allergy (CMA). The aim was to assess the magnitude of this cause. Subjects and Methods. This follow up clinical study was carried out on 63 infants with perianal dermatitis of more than 3 weeks with history of recurrence. Definitive diagnosis was made for each infant through medical history taking, clinical examination and investigations including stool analysis and culture, stool pH and reducing substances, perianal swab for different cultures and staining for Candida albicans. Complete blood count and quantitative determination of cow’s milk-specific serum IgE concentration were done for all patients. CMA was confirmed through an open withdrawal-rechallenge procedure. Serum immunoglobulins and CD markers as well as gastrointestinal endoscopies were done for some patients. Results. Causes of perianal dermatitis included CMA (47.6%), bacterial dermatitis (17.46%), moniliasis (15.87%), enterobiasis (9.52%) and lactose intolerance (9.5%). Predictors of CMA included presence of bloody and/or mucoid stool, other atopic manifestations, anal fissures, or recurrent vomiting. Conclusion. We can conclude that cow’s milk allergy is a common cause of recurrent perianal dermatitis. Mucoid or bloody stool, anal fissures or ulcers, vomiting and atopic manifestations can predict this etiology.

A. A. Kotby, H. M. Elnabawy, W. M. El-Guindy, and R. F. Abd Elaziz — Sun, 02 Sep 2012 14:02:39 +0000

Tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease. The aim of this study was to examine the exercise performance of young patients following the repair of TOF and to assess the influence of different variables related to the surgical repair on exercise testing. This study was conducted on 21 patients (16 males and 5 females) operated on for TOF compared to 15 healthy age- and sex-matched control children. The patients' median age at time of the study was 8 years (range 5–13 years) while age at surgical repair was 5 ± 2.1 years (range 2–10 years). Patients were subjected to 2D and color Doppler echocardiographic examination. Treadmill exercise stress testing was performed for all subjects according to modified Bruce protocol. The resting ECGs of all patients revealed normal sinus rhythm and RBBB. Cases had lower exercise capacity when compared to control subjects and those with aortopulmonary shunt showed significantly lower exercise performance when compared to those without aortopulmonary shunt. In conclusions, exercise tolerance after total correction of TOF is slightly impaired on short-term followup with more affection among patients with previous aortopulmonary shunts. The present study did not reveal any serious ventricular arrhythmia.

The Use of Ketogenic Diet in Pediatric Patients with Epilepsy

Amanda Misiewicz Runyon and Tsz-Yin So — Tue, 28 Aug 2012 09:51:24 +0000

A ketogenic diet is a nonpharmacologic treatment strategy to control refractory epilepsy in children. Although this diet has been used successfully to reduce seizures since the 1920s, the anticonvulsant mechanism of ketosis remains unknown. The initiation of the diet requires an average four-day hospitalization to achieve ketosis in the patient as well as to provide thorough education on diet maintenance for both the patient and the caregivers. A ketogenic diet, consisting of low carbohydrate and high fat intake, leaves little room for additional carbohydrates supplied by medications. Patients on ketogenic diets who exceed their daily carbohydrate limit have the risk of seizure relapse, necessitating hospital readmission to repeat the diet initiation process. These patients are at a high risk for diversion from the diet. Patients admitted to the hospital setting are often initiated on multiple medications, and many hospital systems are not equipped with appropriate monitoring systems to prevent clinicians from introducing medications with high carbohydrate contents. Pharmacists have the resources and the expertise to help identify and prevent the initiation of medications with high carbohydrate content in patients on ketogenic diets.

Sexual Knowledge among High School Students in Northwestern Iran

Mon, 27 Aug 2012 16:33:05 +0000

Objectives. Regarding the importance of sexual desire in adolescence period and public and parental concerns about it and considering the lack of studies on sexual knowledge especially in adolescents in Iran, this study was conducted to evaluate the sexual issues in high school girls and boys. Patients and Methods. The cross-sectional study was performed on 2700 high school students. Students were selected through a multi-staged randomized sampling method in Tabriz and by the convenience method in Ardabil and Urmia. Data collection tool was a questionnaire including knowledge questions and measured by a three-point scale. Data were statistically analyzed with SPSS version 11.5 software. Results. 11.8% of the students had a low sexual knowledge, 46.7% had average and 41.5% had a high one. There was no significant difference between male and female students' general sexual knowledge. The highest knowledge was about being aware of the religious rules concerning sex. Conclusion. Adolescents should be trained and acquire information about the different aspects of sexual issues. Female adolescents especially need to be educated about puberty physiology, fertility physiology and STDs.

Component-Resolved Diagnosis in Pediatrics

Ole D. Wolthers — Sun, 05 Aug 2012 10:25:01 +0000

Component resolved diagnosis is a new concept in the investigation of pediatric allergic disease. The aim of the present paper is to review the available data on component resolved diagnosis with respect to implications for investigation of children with allergic disease. In most conditions head-to-head comparisons of component resolved diagnosis with traditional IgE testing have not been performed. Rather than alternatives the molecular methods should be seen as adjuncts to the cheaper traditional specific IgE tests. It may be appropriate to determine IgE antibodies to components as part of the diagnostic work-up in selected cases of peanut and birch pollen allergy and in hymenoptera allergy. However, cost benefit analyses of component resolved diagnosis compared with traditional work-up of allergy are needed. Prospectively planned protocols for assessment of the extent to which component resolved diagnosis may be able to improve the selection of children to immunotherapy and, thus, the efficacy of immunotherapy, are needed. Finally, studies of component resolved diagnosis with microarray technology in screening panels with hundreds of components should be undertaken before it can be determined to which extent such panel screening, if at all, may be helpful in children.

Bacterial Bloodstream Infections in Neonates in a Developing Country

Daynia E. Ballot, Trusha Nana, Charlotte Sriruttan, and Peter A. Cooper — Sun, 05 Aug 2012 09:38:42 +0000

Background. Ongoing surveillance of antimicrobial sensitivity patterns of bacteria isolated in bloodstream infections guides empiric antibiotic therapy in neonatal sepsis. Methods. Sensitivity profiles of neonatal bacterial bloodstream infections in a tertiary hospital were reviewed between 01/06/2009 and 30/06/2010 . Results. There were 246 episodes of bloodstream infection in 181 individuals—(14.06 episodes in10.35 patients/1000 patient days or 14.4 episodes in 10.6 babies/1000 live births. The majority were (93.5%) were late onset and most (54.9%) were gram positive. There were 2.28 sepsis-related deaths /1000 patient days or 2.3/1000 live births. Death was significantly associated with gram-negative infections (𝑃<0.001), multiple gestation (𝑃<0.001), shock (𝑃=0.008), NEC (𝑃=0.002), and shorter duration of hospital stay (𝑃<0.001). Coagulase-negative staphylococcus was isolated in 19.1%, K. pneumoniae ESBL in 12.1%, and A. baumanni in 10.9%. S. agalactiae predominated in early onset sepsis. Methicillin resistance was present in 86% of CoNS and 69.5% of S. aureus; 46% enterococcal isolates were ampicillin resistant. The majority (65%) of K. pneumoniae isolates were ESBL producers. Ampicillin resistance was present in 96% of E. coli. Conclusions. Penicillin and an aminoglycoside would be suitable empiric therapy for early onset sepsis and meropenem with gentamycin or ceftazidime with amikacin for late onset sepsis.

Regional Variation on Rates of Bronchopulmonary Dysplasia and Associated Risk Factors

Thu, 05 Jul 2012 13:45:57 +0000

Background. An abnormally high incidence (44%) of bronchopulmonary dysplasia with variations in rates among cities was observed in Colombia among premature infants. Objective. To identify risk factors that could explain the observed high incidence and regional variations of bronchopulmonary dysplasia. Study Design. A case-control study was designed for testing the hypothesis that differences in the disease rates were not explained by differences in city-of-birth specific population characteristics or by differences in respiratory management practices in the first 7 days of life, among cities. Results. Multivariate analysis showed that premature rupture of membranes, exposure to mechanical ventilation after received nasal CPAP, no surfactant exposure, use of rescue surfactant (instead of early surfactant), PDA, sepsis and the median daily FIO2, were associated with a higher risk of dysplasia. Significant differences between cases and controls were found among cities. Models exploring for associations between city of birth and dysplasia showed that being born in the highest altitude city (Bogotá) was associated with a higher risk of dysplasia (OR 1.82 95% CI 1.31–2.53). Conclusions. Bronchopulmonary dysplasia was manly explained by traditional risk factors. Findings suggest that altitude may play an important role in the development of this disease. Prenatal steroids did not appear to be protective at high altitude.

Objectives. The aim of this randomized controlled prospective study is to evaluate the efficacy of cranberry capsules for prevention of UTI in children with neurogenic bladder caused by myelomeningocele. Patients and Methods. To be eligible for this study, patients had to be diagnosed as neurogenic bladder caused by myelomeningocele, evaluated urodynamically, followed up with clean intermittent catheterization and anticholinergic drugs. Intervention. Six months of treatment with placebo; after a week of wash-out period treatment of cranberry extract tablets (1 capsule/day) for an additional 6 months. Randomization was performed sequentially. Patients and care givers were blinded to drug assignment. Main outcome measure was infection rate. Group comparisons were performed with Wilcoxon test. Results. The study population included 20 (F/M: 13/7) patients with neurogenic bladder with the mean age of 7.25±3.49 (4, 18) years. The median UTI rate was 0.5/year during placebo usage whereas 0/year during cranberry capsule usage. Decrease in infection rate was significant with cranberry capsule usage (𝑃=0.012). Decrease in the percentage of the pyuria was also recorded as significant (𝑃=0.000). Any adverse events or side effects were not recorded. Conclusion. We concluded that cranberry capsules could be an encouraging option for the prevention of recurrent UTI in children with neurogenic bladder caused by myelomeningocele.

Safety and Efficacy of the ACE-Inhibitor Ramipril in Alport Syndrome: The Double-Blind, Randomized, Placebo-Controlled, Multicenter Phase III EARLY PRO-TECT Alport Trial in Pediatric Patients

Sun, 01 Jul 2012 09:13:14 +0000

Introduction. Retrospective observational data show that ACE-inhibitor therapy delays renal failure and improves life expectancy in Alport patients with proteinuria. The EARLY PRO-TECT Alport trial assesses the safety and efficacy of early therapy onset with ramipril in pediatric Alport patients. Methods and analysis. This double-blind, randomized, placebo-controlled, multicenter phase III trial (NCT01485978; EudraCT-number 2010-024300-10) includes 120 pediatric patients aged 24 months to 18 years with early stages of Alport syndrome (isolated hematuria or microalbuminuria). From March 2012, up to 80 patients will be randomized 1:1 to ramipril or placebo. In the event of disease progression during 3-year treatment, patients are unblinded and ramipril is initiated, if applicable. Approximately 40 patients receive open-label ramipril contributing to the safety database. Primary end-points are “time to progression to next disease level” and “incidence of adverse drug events before disease progression.” Treatment effect estimates from the randomized comparison and Alport registry data will be combined in supportive analyses to maximize evidence. Conclusion. Without this trial, ACE inhibitors may become standard off-label treatment in Alport syndrome without satisfactory evidence base. The results are expected to be of relevance for therapy of all pediatric patients with kidney disease, and the trial protocol might serve as a model for other rare pediatric glomerulopathies.

Background. Sensorineural hearing loss after procedures including extracorporeal circulation and hypothermia is greater than general population. Mild hypothermia has a protective role on cochlea; however, deep hypothermia may result in cochlear injury. This research aimed at assessing auditory function in children after open heart surgery in relation to different hypothermic techniques. Subjects and Methods. Forty children with acyanotic heart diseases who underwent open heart surgery were included: group I: twenty patients subjected to mild hypothermia (33° to 37°C), group II: twenty patients subjected to moderate hypothermia (28° to 32°C). Audiological assessment included basic evaluation and otoacoustic emissions. Results. Both groups had distortion-product otoacoustic emissions (DPOAEs) amplitude >3 dB SPL at all frequencies. However, group II showed lower amplitude at overall and at high frequencies (4.416–8.837 KHz) than group I. Transient evoked otoacoustic emissions (TEOAEs) showed partial pass in three patients of group I (15%) and in 15 patients of group II (75%). Moreover, group II showed statistical significant reduction in overall TEOAEs amplitude as well as at high frequencies (2–4 KHz). Conclusions. Patients exposed to moderate hypothermic technique had subtle cochlear dysfunction. Otoacoustic emissions should be used for early detection of subtle cochlear dysfunction in operated cardiac children.

Assessing Modeled CO2 Retention and Rebreathing of a Facemask Designed for Efficient Delivery of Aerosols to Infants

Tue, 26 Jun 2012 11:53:58 +0000

Background. New aerosol drugs for infants may require more efficient delivery systems, including face masks. Maximizing delivery efficiency requires tight-fitting masks with minimal internal mask volumes, which could cause carbon dioxide (CO2) retention. An RNA-interference-based antiviral for treatment of respiratory syncytial virus in populations that may include young children is designed for aerosol administration. CO2 accumulation within inhalation face masks has not been evaluated. Methods. We simulated airflow and CO2 concentrations accumulating over time within a new facemask designed for infants and young children (PARI SMARTMASK® Baby). A one-dimensional model was first examined, followed by 3-dimensional unsteady computational fluid dynamics analyses. Normal infant breathing patterns and respiratory distress were simulated. Results. The maximum average modeled CO2 concentration within the mask reached steady state (3.2% and 3% for normal and distressed breathing patterns resp.) after approximately the 5th respiratory cycle. After steady state, the mean CO2 concentration inspired into the nostril was 2.24% and 2.26% for normal and distressed breathing patterns, respectively. Conclusion. The mask is predicted to cause minimal CO2 retention and rebreathing. Infants with normal and distressed breathing should tolerate the mask intermittently delivering aerosols over brief time frames.

Frontal Plane Motion of the Pelvis and Hip during Gait Stance Discriminates Children with Diplegia Levels I and II of the GMFCS

Mon, 25 Jun 2012 15:15:45 +0000

Objective. To determine if gait waveform could discriminate children with diplegic cerebral palsy of the GMFCS levels I and II. Patients. Twenty-two children with diplegia, 11 classified as level I and 11 as level II of the GMFCS, aged 7 to 12 years. Methods. Gait kinematics included angular displacement of the pelvis and lower limb joints during the stance phase. Principal components (PCs) analyses followed by discriminant analysis were conducted. Results. PC1s of the pelvis and hip in the frontal plane differ significantly between groups and captured 80.5% and 86.1% of the variance, respectively. PC1s captured the magnitude of the pelvic obliquity and hip adduction angle during the stance phase. Children GMFCS level II walked with reduced pelvic obliquity and hip adduction angles, and these variables could discriminate the groups with a cross-validation of 95.5%. Conclusion. Reduced pelvic obliquity and hip adduction were observed between children GMFCS level II compared to level I. These results could help the classification process of mild-to-moderate children with diplegia. In addition, it highlights the importance of rehabilitation programs designed to improve pelvic and hip mobility in the frontal plane of diplegic cerebral palsy children level II of the GMFCS.
