ABSTRACT

INTRODUCTION: The current multi-center, randomized, double-blind study was conducted among children with cerebral palsy (CP) to assess the safety and efficacy of umbilical cord blood mononuclear cell (UCB-MNC). We performed the diffusion tensor imaging to assess the changes in the white matter structure. METHODS: Males and females aged 4 to 14 years old with spastic CP were included. Eligible participants were allocated in 4:1 ratio to be in the experimental or control groups; respectively. Individuals who were assigned in UCB-MNC group were tested for human leukocyte antigen (HLA) and fully-matched individuals were treated with UCB-MNCs. A single dose (5 × 106 /kg) UCB-MNCs were administered via intrathecal route in experimental group. The changes in gross motor function measure (GMFM)-66 from baseline to one year after treatment were the primary endpoints. The mean changes in modified Ashworth scale (MAS), pediatric evaluation of disability inventory (PEDI), and CP quality of life (CP-QoL) were also evaluated and compared between groups. The mean changes in fractional anisotropy (FA) and mean diffusivity (MD) of corticospinal tract (CST) and posterior thalamic radiation (PTR) were the secondary endpoints. Adverse events were safety endpoint. RESULTS: There were 72 included individuals (36 cases in each group). The mean GMFM-66 scores increased in experimental group; compared to baseline (+ 9.62; 95%CI: 6.75, 12.49) and control arm (ß: 7.10; 95%CI: 2.08, 12.76; Cohen's d: 0.62) and mean MAS reduced in individuals treated with UCB-MNCs compared to the baseline (-0.87; 95%CI: -1.2, -0.54) and control group (ß: -0.58; 95%CI: -1.18, -0.11; Cohen's d: 0.36). The mean PEDI scores and mean CP-QoL scores in two domains were higher in the experimental group compared to the control. The imaging data indicated that mean FA increased and MD decreased in participants of UCB-MNC group indicating improvements in white matter structure. Lower back pain, headaches, and irritability were the most common adverse events within 24 h of treatment that were related to lumbar puncture. No side effects were observed during follow-up. CONCLUSIONS: This trial showed that intrathecal injection of UCB-MNCs were safe and effective in children with CP. TRIAL REGISTRATION: The study was registered with ClinicalTrials.gov ( NCT03795974 ).

ABSTRACT

BACKGROUND: Inflammatory bowel disease (IBD) has both intestinal and extraintestinal manifestations. Inflammatory bowel disease is a known risk factor for cerebral venous thrombosis (CVT) in adults and children. The precise mechanism of the thrombotic event is unclear in IBD patients. We report a case of ulcerative colitis with CVT admitted for acute relapse. CASE PRESENTATION: A 12-year-old boy, who was a known case of ulcerative colitis since 12 months ago, was admitted to our hospital because of bloody diarrhea and recurrent colicky abdominal pain. On the third day of admission, the patient complained of severe headache. The level of consciousness decreased gradually during 12 hours and became aphasic later. One episode of tonic-clonic seizure happened 18 hours after the onset of headache. Neurologic examination showed right hemiparesis. Physical examinations, including blood pressure and fundoscopy were unremarkable on the last admission. Brain computed tomography (CT) showed intraparenchymal hemorrhage in the left temporal lobe with asymmetric increased density in the left lateral sinus. The magnetic resonance imaging (MRI) results revealed abnormal hyperintense signal in the left lateral sinus in T1WI and T2WI, which is compatible with thrombosis (loss of signal) in magnetic resonance venography (MRV). Low-molecular-weight heparin was administered according to consultation with a hematologist and continued post-discharge. The patient's condition improved slowly, and neurologic evaluation was normal after three months. CONCLUSION: Cerebrovascular events, such as cerebral venous thrombosis (CVT) or cerebral arterial infarction (CAI), are rare extraintestinal manifestations of PIBD but probably the most common forms of thromboembolism in children. Probably, treatment of CVT with anticoagulants is the best way of management. A comprehensive study is essential to understand the choice, efficacy, duration, and primary and secondary prophylaxis protocol with anticoagulants.

ABSTRACT

Movement disorders are common neurologic disturbances in childhood. There are two major types of movement disorders. Hypokinetic disorders are with paucity of voluntary movements and are very uncommon in pediatric age group. Hyperkinetic movement abnormalities are very common in children and defined as abnormal repetitive involuntary movements. Movement disorders in childhood and even in adolescents are different in etiology, timing, treatment and prognosis versus adulthood movement abnormalities. In this brief article, we reviewed common types of hyperkinetic abnormal movements in children and adolescents with emphasis on etiologies, new classifications and recent treatment strategies.

ABSTRACT

OBJECTIVE: This study was conducted to predict the response to treatment in patients treated with anti-epilepsy drugs. MATERIAL AND METHODS: This analytical questionnaire-based study was conducted in 2014 among 128 patients with epilepsy admitted to Mofid Children's Hospital, Tehran, Iran. The inclusion criteria were children 2 months to 12 yr of age with epilepsy and patients who experienced fever and seizure attacks at least once were excluded from the study. Patients were followed up for 6 months and the response to their treatment was recorded. The good response to treatment was defined as the absence of seizure with two drugs during follow up. RESULTS: Seventy-two patients (56.3%) were boys. The age of the first seizure was under 2 yr old in 90 patients (70.3%). History of febrile convulsion, family history of epilepsy and history of asphyxia was found in 16 (12.5%), 41 (32%), and 27 (21.1%) patients, respectively. Seizure etiology was idiopathic in 90 patients (70.3%), and the number of seizures was 1-2 in 36 patients (28.1%). Overall, 57 patients (44.5%) had cerebral lesion according to CT scan or MRI, and EEG was abnormal in 101 patients (78.9%). In 6-month follow-up, 40 patients (31.3%) responded well to the treatment and 88 patients (68.8%) responded poorly to the treatment. History of asphyxia (OR = 6.82), neonatal jaundice (OR = 2.81) and abnormal EEG (OR = 0.19) were effective factors in response to treatment. CONCLUSION: Abnormal EEG is an effective factor in treatment response in the children studied.

ABSTRACT

OBJECTIVE: This study was conducted on the demographic data, clinical characteristics, electroencephalography, neuroradiological findings, and their impact on the recurrence of ataxia. MATERIALS & METHODS: A 3-yr retrospective review of 49 children with ataxia in Mofid Children Hospital, Tehran, Iran was conducted from Apr 2013 to Apr 2016. The demographic, clinical and paraclinical data were recorded in pre-prepared questionnaires. The patients were also classified in two groups of with or without recurrence and the results were compared. The diagnostic etiologies in our patients were classified as brain tumor, drug ingestion, encephalitis, post infectious immune-mediated disorders, pseudoataxia, trauma, congenital malformations of the central nervous system and hereditary ataxias. RESULTS: Forty-nine children with ataxia were enrolled. The mean age of the patients with a recurrence of ataxia was more than those without a recurrence. Neurodevelopmental delay in patients with recurrence was more frequent than those without a recurrence. Abnormal findings in the neuroimaging were seen more in the patients with recurrence than those without recurrence. The most common cause of ataxia in patients with recurrence was hereditary ataxia and in patients without recurrence was a viral post infectious disorder. CONCLUSION: After a mean follow-up period of 16.36 months (range: 2-37 months), 9 cases (18.4%) showed recurrence. Older age, abnormal neuroimaging, and neurodevelopmental delay should be considered as the risk factors of recurrence of ataxia in children.

ABSTRACT

Some reports have shown the association between Moyamoya syndrome and autoimmune diseases. Herewith, we present a 3.5 yr old girl with Henoch- Schönleinpurpura (HSP) who was treated with steroids because of sever colicky abdominal pain. However, central nervous system manifestations such as headache, ataxia and vision impairment developed during 6 months of her outpatient follow-up. More evaluation using MRA revealed intracranial stenosis of internal carotid artery and arterial collaterals that were in favor of Moyamoya syndrome. To our knowledge, this is the first report of Moyamoya syndrome following henoch-schönleinpurpura.

ABSTRACT

OBJECTIVE: Seizure is an emergency in pediatrics. It really matters to the parents of the involved child to have information about the causes, management and prognosis. First unprovoked seizures (FUS) are seizures that occur in patients without fever, trauma or infection. Due to the rapid improvement in diagnostic techniques in the last few decades, the etiology will be revealed and this term will no longer exist. This Study was designed to evaluate brain imaging findings in FUS patients. MATERIALS & METHODS: Ninety-six children with FUS, who were admitted in three major children's hospitals in Tehran, underwent brain imaging and were enrolled into the study. The decision about the type of imaging (CT or MRI) was based on the patient's medical and financial conditions. An expert radiologist in the field of pediatric neuroimaging interpreted the images. RESULTS: Altogether, 27.1% had abnormal findings of which 29.2% were in the brain MRI group and 14.3% were in the brain CT scan group. Abnormal results were gliosis (10.4%), hemorrhage (4.2%), dysgenesis (2.1%), dysmyelination (7.3%), encephalomalacy (1%), atrophy (5.2%) and infarction (2.1%). In some patients, the lesions were in 2 or 3 sites and some had more than one type of lesion. There was no association between the duration, age and type of seizure and imaging abnormlities. However, we found an association between the location of the lesion and the type of seizure. CONCLUSION: We recommend brain imaging in all patients with FUS and apart from some exceptions, brain MRI is superior to CT.

ABSTRACT

Russell-Silver syndrome is a genetic disorder the inheritance pattern of which is mostly sporadic. Some of the features of the syndrome are present at birth, and others appear in later years. The main clinical features include low birth weight, poor growth postnatally, short height, and discrepancies in size between the two sides of the body Abu-Amera et al. (2008), Binder et al. (2011). There is no statistical significant difference in prevalence between males and females. We report a case of Russell-Silver syndrome with intrauterine and postnatal growth retardation, triangular face, and body asymmetry, in addition to torticollis as a novel manifestation. In neck sonography, we found asymmetry of sternocleidomastoid muscles. In conclusion, we describe torticollis as a presentation of Russell-Silver syndrome.

ABSTRACT

OBJECTIVE: Acute seizure attack is a stressful experience both for health care personnel and parents. These attacks might cause morbidity and mortality among patients, so reliable methods to control the seizure preferably at home should be developed. This study was performed to measure the time needed to control seizure attacks using intranasal midazolam compared to the common treatment (intravenous diazepam) and to evaluate its probable side effects. METHODS: This study was conducted as a not blind randomized clinical trial among 60 patients coming to Imam Ali Hospital, Zahedan, Iran. The patients were 2 months to 15 years old children coming to our emergency department suffering from an acute seizure episode. Intranasal midazolam was administered 0.2 mg/kg equally dropped in both nostrils for case group and intravenous diazepam was administered 0.3mg/kg via IV line for control group. After both treatments the time needed to control the seizure was registered by the practitioner. Pulse rate and O2 saturation were recorded at patients' entrance and in minutes 5 and 10 after drug administration. FINDINGS: The time needed to control seizure using intranasal midazolam (3.16±1.24) was statistically shorter than intravenous diazepam (6.42±2.59) if the time needed to establish IV line in patients treated by intravenous diazepam is taken into account (P<0.001). The readings for O2 saturation or heart rate did not indicate a statistically significant difference between two groups of patients either at entrance or 5 and 10 minutes after drug administration. CONCLUSION: Considering the shorter time needed to control acute seizure episodes compared to intravenous diazepam and its safety record, intranasal midazolam seems to be a good candidate to replace diazepam, as the drug of choice, in controlling this condition.
