Saccharomyces Boulardii in Helicobacter Pylori Eradication in Children: A Randomized Trial From Iran

Background:

Helicobacter pylori infects around 50% of the human population and is asymptomatic in 70% of the cases. H. pylori eradication in childhood will not only result in peptic symptoms relief, but will also prevent late-term complications such as cancer. Today, probiotics are being increasingly studied in the treatment of gastrointestinal infections as an alternative or complement to antibiotics.

Objectives:

In this study we aimed to assess the effect of S. boulardii supplementation on H. pylori eradication among children in our region.

Patients and Methods:

In this randomized double-blind placebo-controlled clinical trial 28 asymptomatic primary school children with a positive H. pylori stool antigen (HpSA) exam were randomly allocated into the study group, receiving Saccharomyces boulardii, and the control group receiving placebo capsules matched by shape and size, for one month. The children were followed up weekly and were reinvestigated four to eight weeks after accomplished treatment by HpSA testing. The significance level was set at P < 0.05.

Results:

24 children completed the study. The mean HpSA reduced from 0.40 ± 0.32 to 0.21 ± 0.27 in the study group, indicating a significant difference (P = 0.005). However, such difference was not observed in the control group (P = 0.89). Moreover, the HpSA titer showed a 0.019 ± 0.19 decrease in the study group whereas the same value was 0.0048 ± 0.12 for the controls, again stating a significant difference (P = 0.01).

Conclusions:

Saccharomyces boulardii has a positive effect on reducing the colonization of H. pylori in the human gastrointestinal system but is not capable of its eradication when used as single therapy.     

Th1/Th2 Cytokine Profile and Its Diagnostic Value in Mycoplasma pneumoniae Pneumonia

Background:

The levels of Th₁/Th₂ cytokine can alter in pathogenic infection in children with pneumonia.

Objectives:

To evaluate Th₁/Th₂ cytokine profile and its diagnostic value in M. pneumoniae pneumonia in children.

Patients and Methods:

Children with M. pneumoniae mono-infection and 30 healthy children were tested with cytokines assay. We used real time PCR to detect M. pneumoniae in children with pneumonia.

Results:

M. pneumoniae test was positive in 2188 (16.62%) out of 13161 pneumonia children. Children aged 5 - 9 years had the highest rate and summer was a season with high rate of M. pneumoniae incidence in Zhejiang province. During the course of study, in 526 pneumonia children with M. pneumoniae mono-infection and 30 healthy children cytokines assay was performed. IL-2 level of M. pneumoniae pneumonia children was lower than that of healthy children (median levels, pg/mL: IL-2: 3.2 vs. 5.7, P = 0.00), while IL-4, IL-10 and IFN-γ were higher than in healthy children (median levels, pg/mL: IL-4: 3.2 vs. 1.5, P = 0.00; IL-10: 5.6 vs. 2.5, P = 0.001; IFN-γ: 20.4 vs. 4.8, P = 0.001).

Conclusions:

IL-2 decreases and IL-4, IL-10 and IFN-γ increase in children with M. pneumoniae pneumonia, which has a promising prospect in diagnosis of this disease in clinical practice.     

Triage of the child with abdominal pain: A clinical algorithm for emergency patient management

OBJECTIVE:

To create a simplified clinical algorithm for the triage of children with abdominal pain.

DESIGN:

Retrospective analysis.

SETTING:

Emergency room at the Children’s Hospital of Eastern Ontario, Ottawa, Ontario.

METHODS:

A data mining methodology (rough sets analysis) was applied to a randomized data set obtained from 175 emergency room admission charts of patients. Patients were placed into two diagnostic decision classes: appendicitis confirmed by a pathological report, and resolution (this classification implied the resolution of all clinical complaints and physical findings, with no pathological diagnosis and no operative procedure).

RESULTS:

Nine clinical symptoms and signs were identified as being important in the management of children with abdominal pain. A clinically based algorithm for the triage of such children was developed.

CONCLUSIONS:

It is possible to develop a clinical algorithm for the triage of children with abdominal pain that can also be used by nonmedical professionals. A template for such an algorithm can be used as the basis for diagnosing other paediatric emergencies, such as chest pain, headaches and joint pain.     

Staphylococcus aureus bloodstream infections in children: A population-based assessment

BACKGROUND:

Although Staphylococcus aureus is a major cause of bloodstream infections, population-based data on these infections in children are limited.

OBJECTIVE:

To describe the epidemiology of S aureus bacteremia in children.

METHODS:

Population-based surveillance for all incident S aureus bacteremias was conducted among children (18 years of age or younger) living in the Calgary Health Region (Alberta) from 2000 to 2006.

RESULTS:

During the seven-year study, 120 S aureus bloodstream infections occurred among 119 patients; 27% were nosocomial, 18% health care associated and 56% community acquired. The annual incidence was 6.5/100,000 population and 0.094/1000 live births. A total of 52% had a significant underlying condition, and this was higher for nosocomial cases. Bone and joint (40%), bacteremia without a focus (33%), and skin and soft tissue infections (15%) were the most common clinical syndromes. Infections due to methicillin-resistant S aureus were uncommon (occurring in one infection) and three patients (2.5%) died.

CONCLUSIONS:

S aureus bacteremia is an important cause of morbidity in the paediatric age group. Underlying medical conditions and implanted devices are important risk factors. Methicillin-resistant S aureus and mortality rates are low.     

Primary Antibiotic Resistance to Helicobacter pylori Strains Isolated From Children in Northern Iran: A Single Center Study

Background:

Initial resistance to antibiotics is the main reason for the failure of Helicobacter pylori (H. pylori) eradication in children.

Objectives:

As we commonly face high antibiotic resistance rates in children, we aimed to determine the susceptibility of H. pylori to common antibiotics.

Patients and Methods:

In this cross-sectional in vitro study, 169 children younger than 14 years with clinical diagnosis of peptic ulcer underwent upper gastrointestinal endoscopy. Biopsy specimens from stomach and duodenum were cultured. In isolated colonies, tests of catalase, urease, and oxidase as well as gram staining were performed. After confirming the colonies as H. pylori, the antibiogram was obtained using disk diffusion method.

Results:

Culture for H. pylori was positive in 12.3% of the specimens, urease test in 21.3%, serological test in 18.9% and stool antigen test was positive in 21.9%. We could show high specificity but moderate sensitivity of both histological and H. pylori stool antigen tests to detect H. pylori. The overall susceptibility to metronidazole was 42.9%, amoxicillin 95.2%, clarithromycin 85.7%, furazolidone 61.9%, azithromycin 81.0%, and tetracycline 76.2% with the highest resistance to metronidazole and the lowest to clarithromycin.

Conclusions:

In our region, there is high resistance of H. pylori to some antibiotics including metronidazole and furazolidone among affected children. To reduce the prevalence of this antibiotic resistance, more controlled use of antibiotics should be considered in children.     

Polymerase chain reaction detection of Kingella kingae in children with culture-negative septic arthritis in eastern Ontario

BACKGROUND:

The bacterium Kingella kingae may be an under-recognized cause of septic arthritis in Canadian children because it is difficult to grow in culture and best detected using molecular methods.

OBJECTIVES:

To determine whether K kingae is present in culture-negative joint fluid specimens from children in eastern Ontario using polymerase chain reaction (PCR) detection methods.

METHODS:

K kingae PCR testing was performed using residual bacterial culture-negative joint fluid collected from 2010 to 2013 at a children’s hospital in Ottawa, Ontario. The clinical features of children with infections caused by K kingae were compared with those of children with infections caused by the ‘typical’ septic arthritis bacteria, Staphylococcus aureus and Streptococcus pyogenes.

RESULTS:

A total of 50 joint fluid specimens were submitted over the study period. Ten were culture-positive, eight for S aureus and two for S pyogenes. Residual joint fluid was available for 27 of the 40 culture-negative specimens and K kingae was detected using PCR in seven (25.93%) of these samples. Children with K kingae were significantly younger (median age 1.7 versus 11.3 years; P=0.01) and had lower C-reactive protein levels (median 23.8 mg/L versus 117.6. mg/L; P=0.01) than those infected with other bacteria.

CONCLUSIONS:

K kingae was frequently detected using PCR in culture-negative joint fluid specimens from children in eastern Ontario. K kingae PCR testing of culture-negative joint samples in children appears to be warranted.     

Eradication of Helicobacter pylori in Children by Triple Therapy Regimens of Amoxicillin,Omeprazole, and Clarithromycin or Azithromycin

Background and Objectives:

The present study aimed to evaluate the effect of classical and azithromycin-containing triple therapy eradication regimen against H. Pylori in children, and to determine the level of patients’ tolerance.

Patients and Methods:

This single clinical trial was performed in 2014 on 2 to 15 years old children. All children, in whom H. Pylori infection was confirmed through multiple biopsies of the stomach and required treatment, were enrolled in the study. H. Pylori-positive patients were treated alternately with two different drug regimens; Group OCA received clarithromycin 7.5 mg/kg/day every 12 hours for 10 days, amoxicillin 50 mg/kg/day every 12 hours for 10 days, and omeprazole 1 mg/kg/day every 12 hours for two weeks, and Group OAA received azithromycin 10 mg/kg/day once a day (before meal) for 6 days along with amoxicillin and omeprazole. Four to six weeks after completion of treatment, patients’ stool was tested for H. Pylori through the monoclonal method using the Helicobacter antigen quick kit.

Results:

There were no significant differences between the two groups regarding gender and age of patients. Based on ITT analysis, the therapeutic response in the OAA and OCA groups were 56.2% and 62.5%, respectively (P = 0.40). Drug adverse effects were 15.6% in the OCA and 3.1% in the OAA group (P = 0.19).

Conclusions:

The therapeutic response was seen in more than half of the patients treated with triple therapy of H. Pylori eradication regimen including azithromycin or clarithromycin, and there was no significant difference between the two treatment groups.     

The Effect of Stress Management Program Using Cognitive Behavior Approach on Mental Health of the Mothers of the Children With Attention Deficit Hyperactivity Disorder

Background:

Attention deficit hyperactivity disorder is one of the most common psychiatric disorders in children.

Objectives:

The study aimed to evaluate the effectiveness of stress management program using cognitive behavior approach on mental health of the mothers of the children with attention deficit hyperactivity disorder.

Patients and Methods:

In this interventional study, 90 mothers of the children with attention deficit hyperactivity disorder were randomly allocated into three intervention, placebo, and control groups. The general health questionnaire was used to measure mental health. Besides, stress was assessed through the depression-anxiety-stress scale. The two instruments were completed at baseline, immediately after, and one month after the intervention by the mothers. Afterwards, within group comparisons were made using one-sample repeated measurement ANOVA. One-way ANOVA was used for inter group comparisons. Mothers in the placebo group only participated in meetings to talk and express feelings without receiving any interventions.

Results:

At the baseline, no significant difference was found among the three groups regarding the means of stress, anxiety, depression, and mental health. However, a significant difference was observed in the mean score of stress immediately after the intervention (P = 0.033). The results also showed a significant difference among the three groups regarding the mean score of mental health (P < 0.001). One month after the intervention, the mean difference of mental health score remained significant only in the intervention group (P < 0.001).

Conclusions:

The study findings confirmed the effectiveness of stress management program utilizing cognitive behavior approach in mental health of the mothers of the children with attention deficit hyperactivity disorder.     

Flixweed vs. Polyethylene Glycol in the Treatment of Childhood Functional Constipation: A Randomized Clinical Trial

Background:

Polyethylene glycol (PEG) is often considered as the first-line treatment for functional constipation in children. Descurainia sophia (L.) Webb et Berth (D. sophia) is a safe recommended medicine in Iranian folk and Traditional Persian Medicine for the treatment of constipation.

Objectives:

To clinically compare D. sophia with PEG 4000 (without electrolyte) in pediatric constipation and to assess its efficacy and side effects.

Patients and Methods:

120 patients aged 2 - 12 years with constipation for at least 3 months were included in an 8 weeks lasting randomized controlled trial within two parallel-groups. Children received either PEG, 0.4 g/kg/day, or D. sophia seeds, 2 grams (for children aged 2 - 4 years) and 3 grams (for those aged > 4 years) per day.

Results:

A total of 109 patients completed the study (56 in D. sophia and 53 in PEG group). At the end of the study, 36 (64.3%) patients in D. sophia group and 29 (54.7%) in PEG group were out of Rome III criteria (P = 0.205). Median weekly stool frequency in 0, 1, 2, 3 weeks of the treatment was found to be 2, 5, 5, 5 in D. sophia and 3, 4, 4, 5 in PEG group (P = 0.139, 0.076, 0.844, 0.294), respectively. The number of patients who suffered flatulence was less (5, 8.9%) in D. sophia group as compared to PEG group (6, 11.3%) at the end of the trial (P = 0.461). D. sophia taste was less tolerated.

Conclusions:

D. sophia is introduced as a cheap and available medication which can be applied as a safe alternative to conventional PEG in the management of pediatric chronic functional constipation.     

Analysis of Genomic Diversity among Helicobacter pylori Strains Isolated from Iranian Children by Pulsed Field Gel Electrophoresis

Objective:

Presence of genomic diversity among Helicobacter pylori (H. pylori) strains have been suggested by numerous investigators. Little is known about diversity of H. pylori strains isolated from Iranian children and their association with virulence of the strains. Our purpose was to assess the degree of genomic diversity among H. pylori strains isolated from Iranian-children, on the basis of vacA genotype, cagA status of the strains, sex, age as well as the pathological status of the patients.

Methods:

Genomic DNA from 44 unrelated H. pylori strains isolated during 1997–2009, was examined by pulse-field gel electrophoresis (PFGE). Pathological status of the patients was performed according to the modified Sydney-system and genotype/status of vacA/cagA genes was determined by PCR. PFGE was performed using XbaI restriction-endonuclease and the field inversion-gel electrophoresis system.

Findings:

No significant relationship was observed between the patterns of PFGE and the cagA/vacA status/genotype. Also no relationship was observed between age, sex, and pathological status of the children and the PFGE patterns of their isolates. Similar conclusion was obtained by Total Lab software. However, more relationship was observed between the strains isolated in the close period (1997–2009, 2001–2003, 2005–2007, and 2007–2009) and more difference was observed among those obtained in the distant periods (1997 and 2009).

Conclusion:

H. pylori strains isolated from children in Iran are extremely diverse and this diversity is not related to their virulence characteristics. Occurrence of this extreme diversity may be related to adaptation of H. pylori strains to variable living conditions during transmission between various host individuals.     

The Effects of Instrumental Touching on Infant Pain Perception and the Effects of Eutectic Mixture of Local Anesthetics (EMLA) on the Reduction of Pain

Background:

Premature infants, who have to spend the first week of their lives in neonatal intensive care units (NICUs), experience pain and stress in numerous cases, and they are exposed to many invasive interventions. The studies have shown that uncontrolled pain experienced during early life has negative and long-term side effects, such as distress, and such experiences negatively affect the development of the central nervous system

Objectives:

The purpose of the study was to examine the effects of touching on infant pain perception and the effects of eutectic mixture of local anesthetic (EMLA) on the reduction of pain.

Patients and Methods:

Data for the study were collected between March and August 2012 from the neonatal clinic of a university hospital located in eastern Turkey. The population of the study consisted of premature infants who were undergoing treatment, completed the first month and who were approved for Hepatitis B vaccine. The study consisted of two experimental groups and one control group. Information forms, intervention follow-up forms, and Premature Infant Pain Profile (PIPP) were used to collect the data. EMLA cream was applied on the vastus lateralis muscles of the first experimental group before the vaccination. The second experimental group was vaccinated by imitation (placebo), without a needle tip or medicine. Vaccination was carried out using instrumental touch in this group. A routine vaccination was applied in the control group.

Results:

Mean pain scores of the group to which EMLA was applied were lower in a statistically significant way (P < 0.05) compared to the pain scores of the other groups. Moreover, it was determined that even though invasive intervention was not applied to the newborns, the touching caused them to feel pain just as in the placebo group (P < 0.005).

Conclusions:

The results demonstrated that EMLA was an effective method for reducing pain in premature newborns, and the use of instrumental touch for invasive intervention stimulated the pain perception in the newborns.     

Does topical amethocaine gel reduce pain from heel prick blood sampling in premature infants? A randomized double-blind cross-over controlled study

BACKGROUND:

Heel prick blood sampling is the most common painful invasive procedure performed on neonates. Currently, there are no effective ways to provide pain relief from this painful procedure.

OBJECTIVE:

To assess the efficacy of the topical anesthetic amethocaine 4% gel (Ametop, Smith & Nephew Inc, St Laurent) in reducing the pain of heel prick blood sampling in neonates.

METHODS:

A randomized, double-blind, placebo controlled, crossover trial was conducted. Neonates between 33 to 37 weeks’ gestational age in their first seven days of life were eligible. Heel prick blood sampling was performed on each participant twice. Each infant was randomly assigned to receive either amethocaine 4% gel or placebo to the heel for the first prick, and then received the alternative agent for the second prick. Prick pain was assessed using both Premature Infant Pain Profile (PIPP) and Neonatal Infant Pain Scale (NIPS). Squeeze pain was assessed by NIPS.

RESULTS:

Ten babies were recruited. There were no significant differences in the average PIPP and NIPS scores between the treatment and placebo groups for both prick and squeeze pains from heel prick blood sampling. For prick pain, linear-regression showed significant correlation between the PIPP and NIPS scores. No adverse reactions were observed after application of either the active or placebo agents.

CONCLUSION:

Topical amethocaine 4% gel is not shown to reduce prick and squeeze pains significantly from heel prick blood sampling in neonates between 33 to 37 weeks’ gestational age. Further studies are needed to find ways to provide effective pain relief from this common procedure.     

Oral Zinc Sulfate as Adjuvant Treatment in Children With Nephrolithiasis: a Randomized,Double-Blind,Placebo-Controlled Clinical Trial

Background:

Nephrolithiasis in children is associated with a high rate of complications and recurrence.

Objectives:

Since some evidences reported that zinc has an important place amongst inhibitors of crystallization and crystal growth, we decided to assess the effectiveness of oral zinc sulfate as adjuvant treatment in children with nephrolithiasis.

Patients and Methods:

This was a randomized, double-blind, placebo-controlled clinical trial. 102 children in the age range 1 month to 11 years with first nephrolithiasis were recruited. Patients were randomly divided into two equal groups (intervention and control groups). Intervention group received conservative measures for stones and 1 mg/kg/day (maximum 20 mg/day) oral zinc sulfate syrup for 3 months. Control group received placebo in addition to conservative measures, also for 3 months. Patients were followed up by ultrasonography for 9 months, in 5 steps (at the end of 1st, 2nd, 3rd, 6th and 9th month after treatment) assessing size and number of stones in the kidneys.

Results:

Only at the end of the first month, the average number (intervention: 1.15 ± 3.78, control: 1.3 ± 2.84) (P = 0.001) and size (cm) (intervention: 0.51 ± 1.76, control: 0.62 ± 1.39) (P = 0.001) of stones was significantly lower in the intervention group, and in other points there was no significant therapeutic efficacy in oral zinc adjuvant treatment compared to conservative treatment alone. Also, during the 9-month follow-up, the number and size of stones in both groups decreased significantly (both: P < 0.0001) in a way that the decrease in the intervention group showed no difference with the control group.

Conclusions:

Adjuvant treatment with zinc is not more effective than consecutive treatment in children with nephrolithiasis. However, further studies are recommended due to the lack of clinical evidence in this field.     

Effects of Probiotics on Quality of Life in Children with Cystic Fibrosis; A Randomized Controlled Trial

Objective

Patients with cystic fibrosis (CF) usually have abnormal intestinal microbiota and dysregulated immune mediators due to massive exposure to antibiotics. Probiotics as immunomodulatory and anti-inflammatory substances are considered to improve both clinical and biochemical intestinal and pulmonary function in CF patients. We decided to investigate the effects of probiotics on quality of life and pulmonary exacerbations in children with cystic fibrosis.

Methods

In a prospective, randomized, controlled clinical trial, 37 CF patients (2-12 years old) were randomly divided into two groups. 20 patients of probiotic group took probiotics (2×10⁹CFU/d) for one month while 17 patients of control group took placebo capsules. Quality of life was determined using PedsQL™4.0 questionnaire at the beginning, then three and six months after completing the treatment period. Rate of pulmonary exacerbation in probiotic group patients was also evaluated during three months after intervention and compared to the same three months of the previous year. Results were analyzed using SPSS (11.5). P<0.05 was considered statistically significant.

Findings

Significant improvement was observed in the mean total score of parent reported quality of life among probiotic group patients in comparison with placebo group at 3^rd month (P=0.01), but this was not significant at 6^th month of probiotic treatment. Rate of pulmonary exacerbation was significantly reduced among probiotic group (P<0.01).

Conclusion

Probiotics are considered as useful nutritional supplements on reducing number of pulmonary exacerbations and improving quality of life in patients with cystic fibrosis. Effects of probiotics seem to be temporary and probably continuous ingestion might have more stable improving effects on quality of life.     

Predictors of abdominal pain in schoolchildren: a 4-year population-based prospective study

Background

Chronic abdominal pain (CAP) is common among schoolchildren, but risk factors for its onset are still largely unknown.

Aims

To determine the frequency of onset of CAP in schoolchildren and investigate risk factors for its development.

Methods

1411 schoolchildren aged 11–14 years were recruited from schools in North West England. Information was collected on recent pain symptoms and potential risk factors for developing CAP. Participants were followed up 1 and 4 years later and new episodes of CAP were identified.

Results

22% reported new‐onset abdominal pain at 1‐year follow‐up which persisted at 4‐year follow‐up (CAP). CAP was almost three times higher in girls than boys (34% vs 13%; χ²: 26.0; p<0.001). In girls, reporting headache at baseline was the only predictive factor for CAP onset: those reporting headaches experienced a doubling in the risk of symptom onset (relative risk: 2.1; 95% confidence interval: 0.95 to 4.7). In contrast, in boys, development of CAP was independently predicted by daytime tiredness (3.0; 1.2 to 7.6), lack of school enjoyment (2.0; 0.95 to 4.2), adverse psychosocial exposures (2.3; 1.2 to 4.5) and taller stature (1.9; 0.8 to 4.5).

Conclusion

Our results suggest that over 20% of adolescent schoolchildren experience new‐onset non‐self‐limiting abdominal pain over a 1‐year period. Future abdominal pain is predicted by previous somatic symptom reporting in girls and both somatic symptom reporting and psychosocial factors in boys. These risk factors indicate a possible mechanism for understanding the development of CAP, and might have important implications for both primary and secondary preventive strategies.Abdominal pain is common in children, with 12‐month prevalence ranging from 20% in population samples¹ to 44% in primary care attendees.² On physical examination, most children display no abnormalities and this has led to the long‐held belief that most abdominal pain is “functional” in origin.³ In the long term, some researchers have demonstrated an increased risk of irritable bowl syndrome among adults with a history of childhood abdominal pain,⁴ while others have not detected such an association but found that persistent abdominal pain in childhood is associated with adult psychiatric disorders.¹ Such findings have raised speculation that childhood abdominal pain might be a precursor of gastrointestinal and/or psychiatric disorders in adults. Thus, studying its determinants is important in understanding the origin of common and disabling adult illnesses.Previous studies have focused on children with “recurrent abdominal pain” defined as at least three bouts of pain over a period of not less than 3 months. This term, first introduced by Apley and Naish in 1958,⁵ has received criticism for being too general and unclear. Recently, the Subcommittee on Chronic Abdominal Pain of the American Academy of Pediatrics recommended that this term should be retired. Instead, they proposed that “chronic abdominal pain” (CAP) should be used to describe long‐lasting intermittent or constant abdominal pain.⁶Abdominal pain in children often coexists with other somatic pain conditions. A recent study demonstrated that one quarter of children reported pain within the previous 3 months in more than one site, the most common combination being headache and abdominal pain.⁷ Behavioural symptoms are also commonly linked with abdominal pain. Children with such pain have been described as compulsive, highly strung and perfectionist.⁵ In addition, these children experience sleep disturbances and are more prone to suffer from depression.²A major limitation of previous studies is that they have been cross‐sectional or retrospective in design and, therefore, have been unable to establish the temporal nature of any associations. It is clear, therefore, that longitudinal studies are required. Thus, the aims of the current study were to determine the frequency of onset of CAP and to identify risk factors for its development.     

Side Effects of Leukotriene Receptor Antagonists in Asthmatic Children

Background:

Leukotriene receptor antagonists (LTRAs) are drugs which have been widely used more than ten years. As the use of LTRAs increases, our knowledge with respect to their side effects increases as well.

Objectives:

The objective of our study was to evaluat the observed side effects of LTRAs used in patients with astma.

Patients and Methods:

1024 patients treated only with LTRAs owing to asthma or early wheezing were included in the study for a five-year period. The observed side effects of LTRAs in these patients were retrospectively investigated. The side effects were divided into two parts as psychiatric and non-psychiatric.

Results:

Among the 1024 cases included in the study, 67.5% of the patients out of 41 with side effects were male, 32.5% were female and the average age was 6.5 years. The rate of patients with asthma was 63.41% and 36.58% of the patients had early wheezing. It was determined that sex, age and diagnosis (early wheezing or asthma) of the patients were ineffective in the emergence of side effects. The average period for the emergence of side effects was the first month. It was observed that hyperactivity was the most frequently observed psychiatric side effect and that abdominal pain was the non-psychiatric side effect.

Conclusions:

The side effects of LTRAs were common in children. Therefore, patients must be informed at the beginning of the treatment and they must be evaluated at certain intervals.     

No increased risk of relapse after meningococcal C conjugate vaccine in nephrotic syndrome

Objectives

To investigate whether meningococcal C conjugate vaccine (MCCV) caused relapse in children with steroid‐responsive nephrotic syndrome.

Design

A population‐based study was conducted using an active surveillance system, developed to assess adverse events following vaccination, which linked hospital record information on relapses of nephrotic syndrome to community child health population MCCV data. An ecological study looking at hospital admissions for nephrotic syndrome in different age cohorts of children before and after the MCCV introductory campaign was also carried out.

Settings

South East England, and England and Wales.

Patients

52 children having 162 relapses of nephrotic syndrome. Also, all hospital admissions of children aged 2–18 years with steroid‐responsive nephrotic syndrome in England and Wales between 1995 and 2003, relating admissions to when MCCV was introduced in specific age cohorts.

Main outcome measures and analysis method

Self‐controlled case series analysis looking for increased risk of relapse following MCCV and changes in admission rates for nephrotic syndrome (incidence ratio) following the introduction of MCCV to different age cohorts of children.

Results

There was no increased risk of relapse following MCCV in the self‐control case series, where a relative incidence of 0.95 (95% confidence interval (CI) 0.61–1.47) was found in the 6‐month post‐vaccination period, or in the ecological study, which gave an incidence rate ratio of 1.05 (95% CI 0.95 to 1.15) for the quarter when MCCV was introduced and the following two quarters.

Conclusions

We found no association between MCCV and nephrotic syndrome, which is therefore not a contraindication to meningococcal vaccination.     

Atopic Manifestations: Dermatitis,Allergic Rhinitis and Asthma in Patients With Hypogammaglobulinemia

Background:

Most of the hypogammaglobulinemic patients have a clinical history in favor of allergic respiratory disease. Nevertheless, in these patients the importance and prevalence of atopic disorders have not been completely explained.

Objectives:

This study was aimed to evaluate atopic manifestations (dermatitis, allergic rhinitis and asthma) and pulmonary function in patients with hypogammaglobulinemia.

Patients and Methods:

We used the international study of asthma and allergies in childhood (ISAAC) questionnaire in forty-five patients diagnosed with hypogammaglobulinemia and spirometry was done in 41 patients older than 5 years.

Results:

Spirometry results were normal in 21 (51%), and showed obstructive in 15 (37%) and restrictive pattern in 5 (12%) of the 41 patients who were evaluated. By the end of the study, asthma was diagnosed in nine (20%) patients and other atopies (rhinitis and dermatitis) identified in 10 (22%), and four (9%), respectively.

Conclusions:

Atopic conditions should be investigated in the hypogammaglobulinemic patients and the prevalence in these patients may be higher than in normal population. Also, it is recommended to perform a pulmonary function test as a routine procedure in patients with hypogammaglobulinemia and atopy should be assessed in these patients.     

Role of Synbiotics in the Treatment of Childhood Constipation: A Double-Blind Randomized Placebo Controlled Trial

Objective

Constipation is a common problem in children. There is some clinical evidence for the role of probiotics and prebiotics in the treatment of constipated children. This is the first study on the therapeutic effect of synbiotics (combination of probiotics and prebiotic) in treatment of childhood constipation.

Methods

In a double-blind randomized placebo controlled study 102 children aged 4–12 years with functional constipation were assessed according to Rome III criteria for 4 weeks. They were divided into 3 groups: Group A, received 1.5 ml/kg/day oral liquid paraffin plus placebo, group B, 1 sachet synbiotic per day plus placebo and group C, 1.5 ml/kg/day oral liquid paraffin plus 1 sachet synbiotic per day. Frequency of bowel movements (BMs), stool consistency, number of fecal incontinence episodes, abdominal pain, painful defecation per week, success of treatment and side effects were determined in each group before and after treatment.

Findings

The frequency of BMs per week increased in all groups (P<0.001), but it differed between groups and was higher in group C (P=0.03). Stool consistency increased and number of fecal incontinence episodes, abdominal pain and painful defecation per week decreased in all groups similarly and there was statistically no difference between them. No side effects were reported in group B; the main side effect in group A and C was seepage of oil (P<0.001). Treatment success was similar in all groups without any significant difference between them (P=0.6).

Conclusion

This study showed that synbiotics have positive effects on symptoms of childhood constipation without any side effects.
