RESUMEN
OBJECTIVES: This study aimed to analyze the health-related quality of life (HRQoL) of patients with spinal muscular atrophy (SMA) based on the type of SMA, demographic and clinical features and compare HRQoL of these patients with a matched healthy control group. METHODS: This was a case-control study of Patients with SMA in Iran. Sixty-six patients with SMA type II and III aged 8-18 years and also 264 healthy age, sex, and socio-economic matched individuals were enrolled. To assess the quality of life, we used the Persian version of the KIDSCREEN-27. RESULTS: The health-related quality of life between children with type II and type III SMA was not significant in all 5 subscales. However, HRQoL in healthy children was significantly higher than in SMA children in all 5 subscales. CONCLUSION: The quality of life in children with SMA was lower than the healthy control group in all subscales, and physical well-being and psychosocial aspects are the main domains of life impaired by SMA disease. However, no significant difference between the quality of life in children with SMA type II and type III was observed.

We present a 10-year follow-up and describe our experience in managing a case of neonatal severe primary hyperparathyroidism (NSHPT) for the first time in Iran. Microcephaly, mental retardation, and epilepsy may be long time sequels of NSHPT. The brain MRI findings are compatible with an old hypoxic-ischemic event.
RESUMEN
BACKGROUND: Insufficient amounts of survival motor neuron protein is leading to one of the most disabling neuromuscular diseases, spinal muscular atrophy (SMA). Before the current study, the detailed characteristics of Iranian patients with SMA had not been determined. OBJECTIVE: To describe the key demographic, clinical, and genetic characteristics of patients with SMA registered in the Iranian Registry of SMA (IRSMA). METHODS: IRSMA has been established since 2018, and the demographic, clinical, and genetic characteristics of patients with SMA were recorded according to the methods of treat neuromuscular disease (TREAT-NMD) project. RESULTS: By October 1, 2022, 781 patients with 5q SMA were registered. Of them, 164 patients died, the majority of them had SMA type 1 and died during the first 20 months of life. The median survival of patients with type 1 SMA was 23 months. The consanguinity rate in 617 alive patients was 52.4%, while merely 24.8% of them had a positive family history. The most common type of SMA in live patients was type 3. Morbidities were defined as having scoliosis (44.1%), wheelchair dependency (36.8%), tube feeding (8.1%), and requiring mechanical ventilation (9.9%). Most of the registered patients had a homozygous deletion of SMN1, while the frequency of patients with higher copy numbers of SMN2, was less in more severe types of the disease. Earlier onset of the disease was significantly seen in patients with lower copy numbers of SMN2. The neuronal apoptosis inhibitory protein (NAIP) gene deletion was associated with a higher incidence of more severe types of SMA, higher dependency on ventilators, tube feeding, and earlier onset of the disease. CONCLUSIONS: The IRSMA is the first established Iranian nationwide registry of patients with SMA. Using this registry, decision-makers, researchers, and practitioners can precisely understand the epidemiology, characteristics, and genetics of patients with SMA in Iran.

Guillain-Barre syndrome (GBS) is an acute ascending paralysis accompanied by autonomic symptoms like abdominal pain. Here, we presented a 13-year-old boy suffering from lower extremities pain and sensory disturbances with a presumptive diagnosis of GBS who experienced severe disease progression after receiving general anesthesia due to an appendectomy. Whether the progression was due to the natural history of GBS, immunosuppression induced by surgical stress, or usage of anesthetic medications remained unclear.
RESUMEN
BACKGROUND: Celiac disease is the inflammatory entropy caused by hypersensitivity to gluten, which occurs in susceptible individuals. Some studies have suggested a link between celiac disease and epilepsy in children. Our aim was to screen for clinical and paraclinical features of celiac disease in children with intractable epilepsy. METHODS: This was a cross-sectional study. Children aged 2 to 18 years with refractory epilepsy that referred to the pediatric neurology clinic within one year (2018-2019) were enrolled. Demographic and clinical characteristics of patients, especially clinical manifestations of celiac disease, were recorded in a questionnaire. A venous blood sample was sent to determine the total IgA, anti-tTG (IgA), and anti-endomysial antibody (IgA). Endoscopy was performed in cases where the celiac serological test was positive. RESULTS: Seventy children with idiopathic drug-resistant epilepsy (44 boys) were evaluated. The height-for-age index was 49.2% and the weight-for-age index was 38.2% less than normal. Constipation (48.6%), anorexia (25.7%), and abdominal pain (21.4%) were the most common gastrointestinal symptoms. Celiac serological tests were negative in all children. Therefore, endoscopy and bowel biopsy were not performed in any case. CONCLUSION: Celiac disease was not found in any patient with intractable epilepsy. Gastrointestinal symptoms and growth disorders in this group may be related to the underlying disease or medications and not to celiac disease.
RESUMEN
Macrocephaly is one of the most frequent reasons for referral to a pediatric neurologist. Benign enlargement of subarachnoid space (BESS) in infancy is the most common cause of macrocephaly and characterized clinically with large head circumference, normal or mildly motor and language delay and increased cerebrospinal fluid (CSF) in the subarachnoid space with normal ventricles or mild ventriculomegaly. In this review, we describe the etiology, epidemiology, clinical presentation, pathogenesis, neuroimaging, differential diagnosis, treatment and outcome of this entity from current literature with emphasis on diagnostic work-up.
RESUMEN
Spinal muscular atrophy with respiratory distress type 1 (SMARD1) is a rare autosomal recessive neuromuscular disorder that involves the anterior horn motor neurons. It is a disease with a poor prognosis presenting with progressive distal motor weakness and respiratory insufficiency from diaphragmatic paralysis followed by distal muscle weakness before 6 months of age. With the intent to spread the awareness of this rare and life-threatening disease, we report a 2.5-month-old female infant with a subsequent diagnosis of SMARD1, who was admitted in our pediatric intensive care unit with chief complaint of progressive respiratory distress and poor feeding.
RESUMEN
BACKGROUND: Benign convulsion with mild gastroenteritis is a new clinical entity that occurs in children who are otherwise healthy. METHOD: This cohort study held among patients with afebrile convulsion and accompanying gastroenteritis in a tertiary children hospital during a 2-year period. Demographic and clinical data were analyzed. Neurodevelopmental milestones were observed during a follow-up period of 12 to 24 months. RESULTS: Twenty-five patients aged 3 to 48 months with female predominance were enrolled. Ninety-three percent of cases experienced generalized tonic-clonic seizures. One-third of seizures occurred in clusters. Primary laboratory findings and electroencephalography were normal except for 3 with few epileptic waves. During the follow-up period, no seizure recurrence happened. Long-term antiepileptic treatment was unnecessary. CONCLUSION: Afebrile convulsion accompanying mild gastroenteritis is a convulsive disorder with reassuring prognosis. Due to its benign course, comprehensive neurodiagnostic evaluation and long-term antiepileptic drugs are usually avoidable.
RESUMEN
Evaluation of magnesium levels in serum and cerebrospinal fluid of patients with febrile convulsion (FC) hospitalized in Bahrami hospital in Tehran in 2010-2011. In the past, decreased levels of magnesium in serum and CSF of patients with FC were reported. The purpose of this study was to identify the possible role of magnesium in febrile seizures in children. Identifying this condition, we may control seizures and also prevent subsequent convulsion. In this cross-sectional study, inclusion criteria were the existence of convulsion due to fever and exclusion criteria were having a known neurological disease which could induce a seizure, and children younger than one month. In each group (cases include children with febrile convulsion and controls include febrile children without convulsion), Mg was measured in blood, and cerebrospinal fluid of 90 children and then they were compared. The data were analyzed by SPSS (α=0.05). The mean serum and CSF levels of Mg in case and control groups were equal (P<0.87 and P<0.22 respectively). There was no difference between two groups in terms of sex, but mean age was significantly different (P<0.003). There was not an association between serum and CSF levels of magnesium and the presence of FC. Therefore, it's not suggested to measure the level of magnesium in serum or CSF in children with fever routinely.

OBJECTIVE: Altered mental status is a common cause of intensive care unit admission in children. Differentiating structural causes of altered mental status from metabolic etiologies is of utmost importance in diagnostic approach and management of the patients. Among many biomarkers proposed to help stratifying patients with altered mental status, spinal fluid lactate dehydrogenase appears to be the most promising biomarker to predict cellular necrosis. MATERIALS & METHODS: In this cross sectional study we measured spinal fluid level of lactate dehydrogenase in children 2 months to 12 years of age admitted to a single center intensive care unit over one year. Spinal fluid level of lactate dehydrogenase in 40 pediatric cases of febrile seizure was also determined as the control group. RESULTS: The study group included 35 boys (58.3%) and 25 girls (41.7%). Their mean age was 2.7+/-3 years and their mean spinal fluid lactate dehydrogenase level was 613.8+/-190.4 units/liter. The control group included 24 boys (55.8%) and 19 girls (44.2%). Their mean age was 1.3+/-1.2 years and their mean spinal fluid lactate dehydrogenase level was 18.9+/-7.5 units/liter. The mean spinal fluid lactate dehydrogenase level in children with abnormal head CT scan was 246.3+/-351.5 units/liter compared to 164.5+/-705.7 in those with normal CT scan of the head (p=0.001). CONCLUSION: Spinal fluid lactate dehydrogenase level is useful in differentiating structural and metabolic causes of altered mental status in children.
RESUMEN
Status epilepticus and acute prolonged seizures are the most commonly occurring neurological emergencies in children. Such events have high morbidity and mortality rates along with poor long-term outcomes, depending on their duration and causes. Therefore, such seizures warrant urgent treatment using appropriate doses of anticonvulsants. Benzodiazepines, phenobarbital, and phenytoin are the most commonly used anticonvulsants for controlling status epilepticus and acute prolonged seizures. However, these medications have several well-known adverse effects. Previous studies on both adults and children have shown the efficacy and safety of rapid infusion of valproate in controlling status epilepticus. However, few well-designed randomised trials have been carried out in children, and there remains a paucity of data regarding intravenous sodium valproate use in children. Therefore, our aim was to compare the efficacy and safety of rapid loading of valproate with those of intravenous phenobarbital in children with status epilepticus and acute prolonged seizures. Sixty children (30 in each group) with convulsive status epilepticus and acute prolonged seizures were enrolled and randomly assigned to receive either valproate or phenobarbital. The main outcome variable was termination of all convulsive activity within 20 min of starting anticonvulsant infusion. Intravenous rapid loading of valproate was successful in seizure termination in (27/30, 90%) of patients compared to phenobarbital (23/30, 77%) (p = 0.189). Clinically significant adverse effects occurred in 74% patients of the phenobarbital group and 24% patients of the valproate group (p < 0.001). In conclusion, rapid loading of valproate is effective and safe in controlling convulsive status epilepticus and acute prolonged convulsive seizures in children. Intravenous valproate should be considered as a suitable choice for terminating status epilepticus and acute prolonged seizures in children.

OBJECTIVE: To compare the effectiveness of intermittent clobazam versus diazepam therapy in preventing the recurrence of febrile seizures and assess adverse effects of each drug. METHODS: This prospective randomized controlled trial was performed on neurologically normal children aged from 6 months to 5 years with a history of simple febrile seizures and normal electroencephalogram without any evidence of acute central nervous system infection. The patients were randomly prescribed with oral clobazam (37 cases) or diazepam (35 cases) when they developed a febrile disease. They were advised to use the medications during the first 48 h of the onset of fever. All the patients were monitored regarding developing seizure and adverse effects of the drugs. All patients were followed for 12 months. RESULTS: Overall, 243 episodes of fever occurred during the period, including 116 episodes in the clobazam group and 127 episodes in the diazepam group. Recurrence of seizures occurred in 2 (1.7%) subjects in the clobazam group, and in 4(3.1%) cases in the diazepam group. (P value=0.474). Twenty cases (54%) in the diazepam group and 5 (14.2%) cases in the clobazam group developed drowsiness and sedation during the follow-up period (P value=0.0001). CONCLUSIONS: Intermittent clobazam therapy seems advantageous to diazepam due to similar efficacy but significantly lower adverse effects such as drowsiness and sedation.

A Prolonged convulsive seizure is the most common neurological medical emergency with poor outcome. An ideal anticonvulsant should be easy-to-use, effective, and safe, and it should also have a long-lasting effect. Benzodiazepines, give via the intravenous or rectal route have generally been used as first-line drugs. In small children, IV access can be difficult and time consuming. Midazolam is a potent anticonvulsant and is rapidly absorbed from the rectal, nasal, and buccal mucosa. Our aim was to evaluate the efficacy and usability of buccal midazolam in controlling seizures in children with acute prolonged seizures, by comparing it with rectal diazepam. Ninety-eight patients were enrolled, with 49 patients in each treatment group. In the buccal midazolam group, 42 (88%) patients were controlled in less than 4 min of drug administration, and all of the patients were controlled within 5 min of drug administration. In the rectal diazepam group, 24 (49%) patients were controlled in less than 4 min and 40 (82%) patients were controlled within 5 min of drug administration. The time for drug administration and drug effect was significantly less with buccal midazolam than with rectal diazepam (p value<0.001). In the buccal midazolam group, 46 (94%) parents were satisfied with their child's treatment and route of drug administration while in the rectal diazepam group, 7 (14%) parents were satisfied. Buccal midazolam was significantly more acceptable than rectal diazepam (p value<0.001). In conclusion, buccal midazolam may be as effective as rectal diazepam but more convenient to use in the controlling acute prolonged seizures in children, especially in situations in which there is a difficulty in gaining IV access, for example, in infants.
