Clinical Characteristics and Appropriateness of Investigations in Children With Headaches at the Emergency Department.

BACKGROUND: Identifying the cause of headaches in pediatric emergency departments (PEDs) can be challenging due to the lack of comprehensive research. This study aims to identify the frequency, characteristics, and unnecessary diagnostic procedures of patients with headaches in the PED setting. METHODS: A six-month cross-sectional study was conducted at the PED of Alexandria University Children's Hospital, including all children with headaches. Children were classified as having primary headache (PH), secondary benign headache (SBH), and secondary serious headache (SSH) according to predetermined criteria. Logistic regression was employed to analyze the risk factors associated with SSH. RESULTS: A total of 164 visits to the PED were recorded, out of a total of 22,662 visits, accounting for approximately 0.72% of all visits and 1.17% of the total number of children admitted. PH was the most common cause, accounting for 61.0% of cases, followed by SSH with 24.4%, whereas SBH was the least common with 13.4%. Abnormal neurological examination (odds ratio, 53.752 [1.628 to 1774.442], P = 0.026∗) was found to have a strong and statistically significant association with SSH in the multivariate analysis. Regarding the appropriateness of the investigations conducted, it was found that over half (66.5%) of the cases had unnecessary neuroimaging, with 52% of these cases being children with PH. CONCLUSIONS: Headaches in children are commonly reported during visits to the PED. PH was the most prevalent, followed by SSH, whereas SBH was the least common. Many of the children received inaccurate first diagnoses and performed unnecessary laboratory tests, neuroimaging, and other tests, mostly electroencephalography.

Screening of behavioral disorders in children with hemophilia.

AIM: To screen types of behavioral problems among children with hemophilia and their relation to the disease parameters. METHODS: Fifty boys, 6-18 years old, with moderate and sever hemophilia were subjected to: history taking, joint evaluation using the Hemophilia Joint Health Score, and behavioral assessment using the Child Behavioral Check List. RESULTS: Patients experienced different patterns of behavior disorder. Patients' age significantly correlated with anxious/depressed behavior, somatic complaints, social problems, aggressive behavior, internalizing behavior, and total behavior problems. Hemophilia severity significantly correlated with social problems, thought problems, aggressive behavior, internalizing behavior, externalizing behavior, and total behavior disorders. Affected joint number significantly correlated with withdrawn/depressed behavior, social problems, thought problems, aggressive behavior, internalizing behavior, and total behavior disorders. A high Hemophilia Joint Health Score of the target joints was significantly correlated with social problems, rule-breaking behavior, aggressive behavior, externalizing behavior, and total behavior disorders. Hemophilic arthropathy duration significantly correlated with somatic complaints, social problems, thought problems, attention problems, aggressive behavior, internalizing behavior, externalizing behavior, and total behavior problems. CONCLUSION: Children with hemophilia had behavioral disorders. The most affected scale was aggressive behavior. The least affected scale was attention problems. Behavioral disorders in children with hemophilia are influenced by the age of the patient, the severity of the disease, the number of joints affected, the duration of hemophilic arthropathy, and the score of joint affected by Hemophilia Joint Health Score.

Gastrointestinal manifestations and their relation to faecal calprotectin in children with autism.

INTRODUCTION: A common comorbidity in autism spectrum disorder (ASD) children is gastrointestinal problems, and a possible link between active gastrointestinal inflammation and autism has been suggested. Faecal calprotectin (FC) is a non-invasive marker for of gastrointestinal inflammation. AIM: To study the level of FC as a marker of bowel inflammation in children with ASD and its possible relation to gastrointestinal manifestations. MATERIAL AND METHODS: Calprotectin levels were assessed in stool samples of 40 ASD children. Autism severity was assessed by the Childhood Autism Rating Scale (CARS). Severity of gastrointestinal symptoms was assessed using a modified version of the 6-Item Gastrointestinal Severity Index (6-GSI) questionnaire. A control group of 40 healthy children matched for age and sex with the cases was also included to compare their levels of FC. RESULTS: Gastrointestinal symptoms were present in 82.5% of children with autism; the most reported offensive stool odour (70%) and the least diarrhoea (17.5%), and a high 6-GSI score was observed in 35% of ASD children. FC levels were elevated in 35% of the cases and in 25% of the control group. The mean levels of FC of cases were significantly elevated compared to levels of controls. FC levels positively correlated with severity of gastrointestinal symptoms (6-GSI) in autistic patients. There was positive correlation between CARS and 6-GSI. CONCLUSIONS: Gastrointestinal manifestations are a common comorbidity in autistic patients. ASD patients have significantly higher FC levels than healthy controls. FC levels are strongly correlated with the severity of gastrointestinal manifestations in ASD children. So, gastrointestinal manifestations among autistic patients could be caused by gastrointestinal inflammation.

Sensory Processing and Gastrointestinal Manifestations in Autism Spectrum Disorders: No Relation to Clostridium difficile.

The role of the gut microbiota in triggering autism is a rapidly emerging field of research. Gut microbiota have been incriminated because autistic children often have gastrointestinal symptoms. Pathogenic gut bacteria in children with autism spectrum disorders (ASD) have been reported. The present study aimed to assess Clostridium difficile in the stool of children with ASD and its relation to gastrointestinal (GI) comorbidities, autism severity, and sensory impairment. The study included 58 ASD patients, 45 of their neurotypical siblings, and 45 unrelated controls. Childhood Autism Rating Scale (CARS) was used to assess the severity of autism. Sensory problems were evaluated using the Short Sensory Profile (SSP). GI symptoms were assessed with a modified six-item GI Severity Index (6-GSI) questionnaire. Quantitative real-time PCR was done for the detection and quantitation of C. difficile and its toxins A and B. C. difficile was detected in 25.9%, 40%, and 15.6% of ASD cases, siblings, and unrelated control respectively. Regarding toxin A and B production, 73.3%, 77.8%, and 71.4% of C. difficile in positive ASD, siblings, and unrelated control cases respectively were toxigenic. There was no statistically significant difference between the three groups as regards C. difficile qualitative, quantitative, and toxin production results. In conclusion, C. difficile is not specifically prevalent in the gut of children with ASD. Although most of the strains are toxigenic, there were no GI symptoms in the control groups and no statistically significant association with GI Severity Index in autistic cases. Gastrointestinal dysfunction and sensory impairment are common comorbidities in ASD.

Study of the gut Microbiome Profile in Children with Autism Spectrum Disorder: a Single Tertiary Hospital Experience.

The role of gut microbiome was recently raised in the pathogenesis of neurodevelopmental disorders including autism spectrum disorder (ASD). The aim of this study was to elucidate changes in gut microbiome in Egyptian autistic children and its possible correlation with the severity of autism and gastrointestinal (GI) symptoms. The gut bacterial microbiome of 41 ASD children, 45 siblings, and 45 healthy controls were analyzed using quantitative SYBR Green real-time PCR technique targeting 16S rRNA of selected bacteria. The gut microbiome of ASD children and their siblings contained a higher relative abundance of Bacteroides as well as Ruminococcus than controls. Prevotella/Bacteroides (P/B) ratio and Firmicutes/Bacteroidetes (F/B) were significantly lower in both ASD cases and their siblings. The only difference between the autistic cases and their siblings was the significantly higher level of Bifidobacterium in siblings, which appears to offer them a protective role. There was no correlation between the altered gut microbiome and the severity of autism or GI symptoms. The current study showed an evidence of changes in the gut microbiome of autistic children compared to the unrelated control. However, the microbiome profile of siblings was more like that of autistic children than that of unrelated controls indicating that gut microbiota is affected by dietary habits, living conditions together with host genetic factors.

Evaluation and remediation of central auditory processing disorders in children with autism spectrum disorders.

OBJECTIVES: This study was carried out to assess various skills of central auditory processing (CAP) in children with autism spectrum disorders (ASD) and to evaluate the efficacy of auditory training in these children. METHODS: This study is a non-randomized clinical experiment. 30 high functioning ASD children aged from 7 to 12 years were included in the study. They underwent behavioral assessments of CAP skills with subsequent remediation by dichotic training therapy for the children who revealed dichotic deficits. RESULTS: Scores of CAP skills in ASD children are wide-ranging from completely normal to substantially defective and generally lower than those of typically developing children. By auditory training, ASD children improved their dichotic deficits as well as other untrained areas of auditory and language processing skills. CONCLUSIONS: A group of ASD children showed different degrees of abnormalities in CAP that could be measured behaviorally and achieved benefits from auditory training in improving their dichotic listening, auditory and language processing skills.

The correlation between central auditory processing in autistic children and their language processing abilities.

AIM: To study the auditory profile at different levels of the auditory system in children with ASD and to verify the role of (Central) auditory processing disorder as an essential pathology of the autistic disorder or as an associated co-morbidity, and to establish the correlation between CAP findings and the language delay in these cases. PATIENTS: The study included 30 children with definite autistic disorder according to DSM-IV-TR criteria and ADI-R among those attending the outpatient neuropsychiatry clinic of Alexandria University Children Hospital at El Shatby. An informed consent was taken from all patients in this part of the study. Confidentiality of the records was maintained. METHODS: All cases were subjected to complete history taking and examination; special assessment to language skills and evoked potentials were done. RESULTS: The results concluded that (central) auditory processing disorder is an essential pathology of the autistic disorder. Autistic children possess a dysfunctioning or an immature central auditory nervous system at both the brainstem and cortical levels.
