Objectives: Migraine is a chronic and joint disease in children. The results of previous studies on the effectiveness of probiotics in preventing migraine attacks in children have been controversial. This study aims to investigate the effect of probiotics on migraine prophylaxis in children. Materials & Methods: In this clinical trial study, 41 children aged 5 to 15 with migraine enrolled the study in two control and intervention groups. Children in the intervention group (18 children) received propranolol at a dose of 1 mg per kilogram of body weight daily in two divided doses along with a 250 mg Yomogi capsule daily for three months, and children in the control group (23 children), received propranolol along with placebo for three months. The study compared the frequency and duration of headache days, PedMIDAS criteria, and parental satisfaction between the two groups before treatment, as well as one month and three months post-treatment. Results: The number of headache days in both groups decreased over time, but in the intervention group, this decrease was more than the control group was statistically significant (P=0.045). The average PedMIDAS scale after treatment in the intervention group was 3.9 ± 3.8; in the control group, it was 8.4 ± 8.2, which was statistically significant (P=0.047). Parents' satisfaction with the treatment was statistically significantly higher in the intervention group (94.4%) than in the control group (54.5%) (P=0.011). No significant drug complications were seen in any of the two groups. Conclusion: In children with migraine, adding probiotics to migraine treatment reduces the intensity and number of days of children's headaches and increases the Parents' satisfaction with the treatment.

Objectives: Epidemiologic studies point to an increased prevalence of migraine in children in recent decades. Migraine treatment involves acute and prophylactic therapy. Recently, such anti-epileptic drugs as Levetiracetam have been used to treat adult migraines. The present study aimed to compare the efficacy of Levetiracetam, Sodium Valproate, and Propranolol in preventing migraine headaches in children. Materials & Methods: In this clinical trial, children with migraine were randomly divided into three groups. Each group consisted of 13 children. Two groups were treated with Propranolol and Sodium Valproate, respectively. Another group (the case) was treated with Levetiracetam. The patients were assessed based on headache score, PedMIDAS, and headache frequency before and three months after the intervention. Finally, the data was analyzed using descriptive and analytical statistical methods. Results: Levetiracetam significantly reduced the headache severity (P=0.026), frequency (P=0.024), and PedMIDAS score (P=0.001) in children with migraine. However, no significant difference was found between the three groups. The percentage of patients who experienced pain relief was detected as 69.24%, 92.31%, and 30.76% in the Propranolol, Sodium Valproate, and Levetiracetam groups, respectively. Conclusion: This study concluded that Levetiracetam can be used as a migraine prophylaxis drug in children.

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.

Objectives: Migraine headache after tension headache is the most common primary headache in children, and sleep disorders can aggravate the symptoms. Melatonin has been proposed in some studies for prophylaxis of migraine headaches. This study aimed to evaluate melatonin's effect on migraine symptoms in children with migraine headaches and sleep disorders. Materials & Methods: In this randomized clinical trial study, all 30 children aged 5 to 15 years with migraine headaches and sleep disorders were referred to the Pediatric Neurology Clinic and enrolled. Patients were randomly divided into two equal groups; the intervention group was treated with melatonin (3 mg daily) and propranolol (1 mg/kg daily), and the control group was treated with propranolol alone (1 mg/kg daily). The severity of the migraine headaches was assessed with PEDMIDAS and a five-point Likert scale. The children's sleep habits questionnaire (CSHQ) assessed children's sleep disorders. The ANOVA and linear regression methods were used to analyze and compare the findings between the groups. Results: Out of 30 children participating in the study, 9 were girls, and 21 were boys. The number of daily headaches one month (P = 0.02) and four months (P = 0.03) after treatment was significantly lower in the melatonin group compared to the control group. Regarding sleep quality, there was no significant difference between the two groups. Conclusion: Melatonin and propranolol could better alleviate migraine headaches than propranolol alone in children.

OBJECTIVES: In children suffering from febrile seizure, the likelihood of recurrence seems to be high in the early hours following the first episodes in the absence of proper interventions. The present study was aimed at assessing and comparing the outcomes of different preventive interventions in the acute stage after febrile seizure in children. MATERIALS & METHODS: This randomized clinical trial study was performed between September 2015 and September 2016. We enrolled patients aged between 6 and 60 months suffered from febrile seizure and referred to the Pediatric Emergency Department at Besat Hospital in Hamadan. The eligible patients were randomly assigned to the following four receive one of the following groups: group 1 (not receiving any anti-seizure drugs), group 2 (receiving a single dose of phenobarbital) on admission, group 3 (receiving a single dose of phenobarbital on admission continued until the fever is resolved), and group 4 (receiving diazepam until the disappearance of fever). RESULTS: The study population consisted of 248 children. The recurrence rate of seizure in the acute stage was 4.84%. Also, the impact of diazepam and phenobarbital (either as a single dose or as continuous) on the prevention of febrile seizure recurrence in the acute stage has been established. None of the patients had febrile status epilepticus. CONCLUSION: Controlling seizures without prescribing anti-seizure drugs increases the risk for the recurrence of febrile seizure in the acute stage. Different drug regimens for controlling seizure, including diazepam and phenobarbital (as stat or maintenance), may play a similar role in preventing the occurrence of febrile seizure.

OBJECTIVES: Epilepsy is a relatively common disease in childhood. In some patients, the electroencephalogram (EEG) is abnormal despite the clinical control of seizures. Studies have identified the adverse effects of epileptic discharges on cognition, learning, behavior, and seizure recurrence in children. This study investigated the Levetiracetam effect on epileptic discharges in the interictal phase of EEG in epileptic children. MATERIALS & METHODS: This clinical trial was conducted on 54 epileptic children aged 2 to 15 years, whose clinical seizures were controlled by sodium valproate in the last six months but still had epileptic discharges in EEG. The participants were divided into two groups: an intervention group (21 people), for which Levetiracetam was added to sodium valproate, and a control group (33 people), for which treatment with sodium valproate alone was continued. The patients were then followed for one year. RESULTS: The percent normalization of epileptic discharges in the intervention and control groups was 66.7% and 57.1% (P = 0.500), respectively. Also, the mean time for the normalization of epileptic discharges in the intervention and control groups was 12.60±8.25 and 20.57±12.67 months (P = 0.042), respectively. CONCLUSION: In children with controlled seizures whose EEG was still abnormal, sodium valproate therapy alone and combined with Levetiracetam effectively reduced the severity of epileptic discharges. However, the addition of Levetiracetam to sodium valproate normalized EEG more rapidly.

OBJECTIVES: Infantile spasms can have irrecoverable adverse effects on a child's brain. Adrenocorticotropic hormone (ACTH) is the most common first-line medication for the treatment of infantile spasms. However, the suitable dose and duration of treatment continue to be debated among specialists. Since high doses of ACTH, which are commonly used, can produce more side effects, lower doses are preferred. The aim of this study was to determine the effect and extent of complications caused by high and low doses of ACTH in children with infantile spasms. MATERIALS & METHODS: This clinical trial was performed on 32 infants with infantile spasms, aged 1.5-18 months. The subjects were divided into high- and low-dose ACTH groups. Treatment continued for two months. The therapeutic effects and complications were then compared over 18 months. RESULTS: The results indicated no significant difference between the groups in terms of the short-term prognosis of convulsions, final prognosis of patients with spasm relapse, EEG changes after treatment, and post-treatment development of hypertension. On the other hand, there was a significant difference in the frequency distribution of restlessness intensity and becoming Cushingoid, which were more frequent in the high-dose group. CONCLUSION: The results indicated that high- and low-dose ACTH are equally effective in controlling spasms, yet the low dose causes fewer side effects.

OBJECTIVE: Sleep disturbances are one of the most common behavioral problems in childhood. Sleep problems have an even greater prevalence in children with epilepsy and are one of the most common comorbid conditions in childhood epilepsy. MATERIALS & METHODS: This descriptive-correlation study with the general goal of determining the effects of epilepsy on sleep habits of epileptic children was conducted in Hamadan, western Iran, in 2014. Sampling was done using convenience sampling techniques. Data were collected using the Early Childhood Epilepsy Severity Scale (E-Chess) and Children's Sleep Habits Questionnaire (CSHQ) and analyzed using SPSS and descriptive and inferential statistics. RESULTS: The mean score of sleep habits was 55/08±6/71. Bedtime resistance (12/14±2/93), parasomnias (11/02±1/84) and sleep anxiety (8/29±2/46) were the most frequent sleep disorders in the studied sample. Based on Pearson's r, there were significant positive bidirectional relationships between bedtime resistance (rs =0.129, P<0.019), parasomnias (rs =0.298, P<0.005), sleep-disordered breathing (rs =0.295, P<0.005), CSHQ total score (rs =0.144, P<0.022) on the one hand, and children's epilepsy severity on the other. CONCLUSION: Sleep problems should not be overlooked, and a comprehensive review of the sleep habits of this group of patients should be conducted.

OBJECTIVES: Headache and sleep problems are commonly reported in children, and both can adversely impact the child's life. We aimed to compare the sleep quality and intensity of headache between school-age children with migraine as well as tension headache and healthy children. MATERIALS & METHODS: In this cross-sectional study, 198 children 6-12 yr old in three groups were enrolled from Aug 2015 to Mar 2016. Migraine and tension headache groups from the Outpatient Clinic of Imam Khomeini of Hamadan, western Iran and healthy group from elementary schools were randomly selected (66 children in each group). Data were collected using demographic questionnaire, Child Sleep Habits Questionnaire (CSHQ), Numeric Scale of Pain Intensity and Wong-Baker Faces Pain Rating Scale. The data were analyzed using SPSS by descriptive statistic and multivariate ANOVA, one way ANOVA, Chi-square, Kruskal-Wallis and linear regression tests. RESULTS: Approximately, 45.5% of children with migraine and 37.9% of them with tension headache had experienced severe headache. Only a significant relationship was seen between mean scores of headache intensity and sleep quality in migraine group (P<0.05). There was a significant difference in mean scores of sleep quality among three groups (P<0.001). CONCLUSION: The children with migraine experienced more unsuitable sleep in duration of severe headache. Highlighting the co-morbidity between intensity of headache and sleep problem of children with migraine and tension headache is important to improve treatment strategies and to know the impact of headache on their normal life.

OBJECTIVES: Acute prolonged seizure is the most common neurological emergency in children. This research was conducted to compare the effect of intravenous phenobarbital and Sodium valproate in control of seizure in children with status epilepticus, referred to emergency ward from Mar to Nov 2013. MATERIALS & METHODS: In this randomized clinical trial, registered with the code number IRCT2015051722300N1, 80 children aged 6 months to 10 years with prolonged seizure and with no response to one dose of diazepam (0.2 mg/kg) administered through IV injection during the five min were selected. Children were randomly divided into two groups, intervention, and control through permutation blocks. In intervention group, intravenous Sodium valproate (20 mg/kg) and in control group, intravenous phenobarbital (20 mg/kg) were prescribed. Data such as age, gender, history of previous seizure, seizure type, and recovery time after receiving drug was recorded in the form. Data analysis was done through descriptive statistics, Chi-square and Independent t- test. RESULTS: Two groups were the same in terms of age and gender and had no statistically significant difference, but they were different in terms of seizure type. In valproate group, 18 patients (45%) and in phenobarbital group, 32 patients (80%) had positive response to the treatment and the chi-square test showed the significant difference. CONCLUSION: With regards to this point that in phenobarbital group, patients had more rapid response to drug in comparison with patients in Sodium valproate group, phenobarbital is a suitable and effective drug for controlling of seizure in children.

OBJECTIVE: Febrile seizures are the most common type of convulsions. Medicinal prophylaxis is sometimes used for children at high risk of recurrent febrile seizure. In certain circumstances, conventional drugs such as diazepam and phenobarbital cannot be used and the need for alternative medicines is felt. This study compared the effectiveness of topiramate and diazepam in preventing the risk of recurrent febrile seizure in children under 2 yr old. MATERIALS AND METHODS: This randomized controlled trial, in Besat Hospital in Hamedan, Iran from 22 Nov 2013 to 22 Nov 2015 (Registered code: IRCT Number: IRCT2015010120527N1), included 54 patients, at risk of recurrent febrile seizure, inhibited from taking phenobarbital. Samples were randomly divided into two groups. The first group received diazepam treatment during fever episodes and the second group received daily dose of topiramate. A one-year follow-up of recurrent febrile seizure and its complications was also conducted. RESULTS: Thirty-four patients (17 patients in each group) completed the one-year course of the trial. Recurrent febrile seizure was not observed in the course of preventive treatment. The prevalence of minor complications was 29.4% in the diazepam group and 48.5% in the topiramate group. No major complication was observed in among the subjects. CONCLUSION: Topiramate can be recommended for preventing recurrent febrile seizure when the use of frontline medicines is not possible.

Malignant salivary gland sarcomas represent a clinically and histologically diagnostic challenge. Primary unclassified sarcomas of the parotid gland consist a rare salivary gland tumor. We report an unusual case of such a tumor, which occurred in the right parotid gland of a 54-year-old male and presented as an asymptomatic painless mass. The pathologoanatomical examination revealed a rhabdoid large-cell unclassified sarcoma. The patient was treated with superficial parotidectomy and adjuvant radiotherapy. No recurrence was noted in a 10-year follow-up period. Due to the rare occurrence of primary unclassified sarcomas, there is no evidence-based treatment of choice. An optimal approach is best planned in a multidisciplinary setting, taking into consideration the resectability of the tumor, individual patient characteristics, presence of local or distant metastatic activity, local infiltrative behavior and tumor stage. A close follow-up of the patient is strongly recommended.

OBJECTIVE: The effect of using omega-3 to prevent migraine attacks has been raised in recent studies. The majority of these studies have been conducted in adults. Conversely, other studies have yet to confirm the effect of omega-3. The main purpose of this study was to assess the effects of omega-3 in the prevention of migraine attacks in children. MATERIALS & METHODS: In this study, children aged 5-15 years with a diagnosis of migraine were randomly assigned to case and control groups. The case group was treated with sodium valproate and 1 g of omega-3; the control group was treated with sodium valproate and a placebo for 2 months. The severity of attacks was evaluated before and after the treatment using PedMIDAS and parental satisfaction (CGI) using a 7-point Likert scale. RESULTS: In this study, 12 cases and 13 controls were enrolled. The average number of headache attacks per month decreased significantly in both groups after starting the treatment but there was no significant difference between the two groups. The severity of attacks decreased significantly in both groups after starting the treatment but it was not significant between them. Examination of the CGI average showed the average was 6.08 (SD = 0.52) in the case group and 6.07 (SD = 0.65) in the control group. CONCLUSION: The present study indicated that omega-3 with a dose of 1 mg per day has no effect in reducing the severity and frequency of migraine attacks in children. Sodium valproate was effective in reducing the frequency and severity of attacks.

BACKGROUND: Sialoblastoma is an extremely rare congenital salivary gland tumor of epithelial origin. It is usually localized in the parotid or submandibular gland and presents primarily at birth or in early childhood. METHODS: We report a case of a 13-year-old girl with a sialoblastoma of the parotid gland presenting as an asymptomatic painless mass. RESULTS: The patient showed multiple recurrences and, based on the histopathological finding of facial nerve infiltration, was treated surgically with total parotidectomy and facial nerve reconstruction. CONCLUSION: Because of the rare occurrence of sialoblastoma, there is no evidence-based treatment of choice. The treatment should be individualized, taking into consideration the patient's age, the high locoregional recurrence rate, the local aggressive characteristics, and the potential metastatic activity of this rare tumor. A close follow-up of the patient is strongly recommended.

OBJECTIVE: Bell's palsy is a rapid onset, usually, unilateral paralysis of the facial nerve that causes significant changes in an individual's life such as a decline in personal, social, and educational performance. This study compared efficacy of combined prednisolone and acyclovir therapy with prednisolone alone. MATERIALS & METHODS: This study is a randomized controlled trial conducted on 43 Children (2-18 years old) with Bell's palsy. The first group of 23 patients was treated with prednisolone and the remaining patients were treated with a combination of prednisolone and acyclovir. The required data were extracted, using an informational form based on the House-Brackmann Scale, which grades facial nerve paralysis. The data were analyzed with Mann-Whitney test using SPSS version 16. RESULTS: The mean age of the first and second group were 8.65 ± 5.07 and 8.35 ± 4.92 years, respectively, (p=0.84). Sixty one percent and 39% of patients in the first group, and 45% and 55% of patients in the second group were male and female, respectively. No significant differences exist between the groups in terms of age and gender. The rate of complete recovery was 65.2% in group I and 90% in the group II (p=0.04). CONCLUSION: The results of this study showed that the combined prednisolone and acyclovir therapy of patients with Bell's palsy is far more effective than treatment with prednisolone alone. Actually, age and gender had no impact on the rate of recovery.

OBJECTIVE: Intractable epilepsy is a major difficulty in child neurology, because the numbers of drugs that are available for treatment are limited and new treatments such as diets must be tried. Now there are some diets available for treating patients with intractable epilepsy. The oldest diet is the classic ketogenic diet and one of the newest diets is the modified Atkins diet. Patients have a harder time accepting the classic ketogenic diet than the Atkins diet, which is easier to accept because the food tastes better. This study compares the efficacy of the ketogenic diet and the Atkins diet for intractable epilepsy in children. MATERIALS & METHODS: This study is a clinical trial survey with sample size of 40 children with refractory epilepsy who were patients at Mofid hospital in Tehran, Iran. Initially, from Jan 2005-Oct 2007, 20 children were treated with the Atkins diet, and then from Oct 2007-March 2010, the other group was treated with the classic ketogenic diet and the results were compared. RESULTS: In this study, response to treatment was greater than a 50% reduction in seizures and at the end of first, second, and third months for the ketogenic diet were 55%, 30%, and 70% and for the Atkins diet were 50%, 65%, and 70%, respectively. CONCLUSION: The results of this study show that there is no significant difference between the classic Ketogenic diet and the Atkins diet at the end of first, second, and third months and both had similar responses to the treatments.

OBJECTIVE: Febrile seizures (FSs) are the most common neurological disorder observed in the pediatric age group. The present study provides information about epidemiological and clinical characteristics as well as risk factors associated with FS among Iranian children. MATERIALS & METHODS: On the computerized literature valid databases, the FS prevalence and 95% confidence intervals were calculated using a random effects model. A metaregression analysis was introduced to explore heterogeneity between studies. Data manipulation and statistical analyses were performed using Stata10. RESULTS: The important viral or bacterial infection causes of FSs were; recent upper respiratory infection 42.3% (95% CI: 37.2%-47.4%), gastroenteritis21.5% (95% CI: 13.6%-29.4%), and otitis media nfections15.2% (95% CI: 9.8%- 20.7%) respectively. The pooled prevalence rate of FS among other childhood convulsions was 47.9% (95% CI: 38.8-59.9%). The meta-regression analysis showed that the sample size does not significantly affect heterogeneity for the factor 'prevalence FS'. CONCLUSION: Almost half of all childhood convulsions among Iranian children are associated with Febrile seizure.

OBJECTIVE: Increasing use of methadone in withdrawal programs has increased methadone poisoning in children. This research aimed to study the causes of incidence of poisoning in children and its side-effects. MATERIALS & METHODS: In this research, The hospital records of all methadone-poisoned children referred to Hamadan's Be'sat Hospital from June 2007 to March 2013, were studied. Children with a definite history of methadone use or proven existence of methadone in their urine, were studied. RESULTS: During 5 years, 62 children with the mean age of 53.24±29.50 months were hospitalized due to methadone use. There was a significant relationship between delayed referral to hospital and increased bradypnea. According to their history, 25.8% and 58.1% of the children had been poisoned by methadone tablet and syrup, respectively. The most common initial complaint expressed by parents, was decreased consciousness (85.5%). During the initial examination, decreased consciousness, meiosis, and respiratory depression were observed in 91.9%, 82.3%, and 69.4% of the cases, respectively. Nine patients required mechanical ventilation. There was a significant relationship between the need for mechanical ventilation and seizure with initial symptom of emesis. There were two cases of death (3.2%), both of which were secondary to prolonged hypoxia and brain death. There was a significant relationship between poor patient prognosis (death) and presence of cyanosis in early symptoms, seizure, hypotension, duration of decreased consciousness, and duration of mechanical ventilation. CONCLUSION: This research indicated that the occurrence of seizure, hypotension, and cyanosis in the early stages of poisoning is associated with an increased risk of side effects and death and are serious warning signs. Early diagnosis and intervention can improve outcomes of methadone-poisoned children.
