Objective: Vitamin D insufficiency/rickets is a metabolic bone disease that leads to insufficient mineralization of bone. Chronic neurological diseases, including cerebral palsy (CP), convulsive disorders, neural tube defects, myopathy, immobility, lack of sun exposure, inadequate nutrition, and antiepileptic drugs (AEDs) can cause vitamin D insufficiency and osteopenia in children.
Materials & methods: In this study, the authors searched the frequency and causative factors of vitamin D insufficiency in children with chronic neurological diseases such as CP, hypoxic-ischemic encephalopathy, mental motor retardation, epilepsy, neurodegenerative and neuromuscular diseases, meningitis-encephalitis sequelae, neural tube defects, paralysis, and paresis. This cross-sectional study included 108 children (forty-five (41.6%) females; sixty-three (58.4%) males), aged between one and 18 years with chronic neurological diseases, and a control group of thirty age-matched healthy children (16 (53.3%) females; 14 (46.7%) males.
Results: Vitamin D levels were significantly lower, and parathyroid hormone (PTH) levels were significantly higher in the patient group than in the control group (p<0.05). The patient group was divided into four subgroups: (i) Epilepsy (n=41; 38%), (ii) Neural tube defects (n=14; 13%), (iii) CP (n=21; 19%), and (iv) other diseases (neurodegenerative and neuromuscular diseases, meningitis sequelae, intracranial hemorrhage, psychomotor retardation, hypoxic-ischemic. encephalopathy) (n=32; 30%) to identify any differences in the measured levels. In the patient group, eighty-three (76.9%) had vitamin D deficiency, and 17 (15.7%) had vitamin D insufficiency, while in the control group, twenty-one (70%) had vitamin D insufficiency. The use of AEDs had no significant effect on serum Ca, P, ALP, PTH, or vitamin D levels (p>0.05), and serum Ca levels were significantly higher in ambulant patients than in non-ambulant patients (p<0.05). Vitamin D levels were significantly higher in the non-ambulant than in the ambulant patients (p<0.05). No rickets was determined in the control group, while in the patient group, nine (8.3%) had level-1 rickets, six (5.6%) had level-2 rickets, and two (1.9%) had level-3 rickets.
Conclusion: Children with chronic neurological diseases have low serum vitamin D levels, and vitamin D prophylaxis is essential in this group.
Objectives: Mutations in TSC1 or TSC2 genes have been proposed as the main causative factors responsible for developing Tuberous Sclerosis Complex (TSC). Given the effect of these two genes on the mTOR pathway, rapamycin has emerged as a novel therapeutic agent. The present study evaluated the effectiveness and safety of rapamycin on the multiple manifestations of TSC.
Materials & methods: Twenty-three eligible children were enrolled in the present cross-sectional study. They were prescribed rapamycin 1mg tablet twice daily for the first two weeks of treatment and then once daily for at least one year. Periodic evaluations through follow-up visits were performed. Besides, growth and developmental statuses were evaluated. All data, including the number and size of brain tuberomas, size of renal angiomyolipomas, and skin lesions, were gathered and recorded, and then analyzed.
Results: During the study period, the mean number of epileptic episodes significantly reduced (p<0.0001), and nine cases were seizure-free at the final visit. The mean number of brain tuberomas decreased from 19.3±11.0 at the initial visit to 11.1±5.6 and 8.2±3.2 in the subsequent visits (p<0.001). The mean size of brain tuberomas similarly decreased from 17.9±18.5 cm at enrollment to 13.7±5.1 cm and 6.9±5.1 cm in the second and third visits, respectively (p=0.029). The mean size of renal angiomyolipomas significantly decreased (p<0.001). A significant trend toward a decrease in the number of skin lesions was observed (p<0.0001). No relationship was observed between the effects of rapamycin and the patient's age or sex (p>0.05). Changes in patients' growth and developmental features were not statistically significant through subsequent visits (p=0.507).
Conclusion: This study revealed the effectiveness and safety of rapamycin on TSC among our patients.
Objectives: The current study aimed to determine the proxy measurements for height in children with Cerebral Palsy (CP).
Materials & methods: In a cross-sectional descriptive study, the length/height of Nigerian children with CP was studied over eighteen months using descriptive statistics. The study subjects comprised children aged 15 months to 17 years with CP. Height/length, weight, arm span, forearm length, mid-upper arm circumference, foot length, head circumference, hip circumference, leg length, and tibia length were measured to the nearest 0.1 cm using standard procedures. The relations between segmental measurements and weight with height were investigated using linear regression.
Results: A total of 31 children were studied. The correlation between height/length and other linear measurements has a significantly strong positive relationship. Regression analysis showed that when used singly, the weight and thigh length offered a high explanation for the height variability with little estimation error. On the other hand, weight had a lower mean difference between observed and predicted height (0.21 and -0.76, respectively), with thigh length overestimating the height.
Conclusion: Weight measurement may be the preferred proxy for height in children with CP.
Objectives: Indicatively, phenobarbital can impair thyroid function in adults and children. The present research aims to evaluate the thyroid hormone levels in preterm neonates who had received phenobarbital treatment.
Materials &methods: This study was conducted on preterm neonates who weighed less or equal to 2500 g when phenobarbital was prescribed for treatment in the first 15 days of life. TSH and total T4 measurements were performed before and three months after initiation of phenobarbital.
Results: In this study, the sum of preterm neonates stood at 94, of which 53 were girls, with a mean birth weight of 2004.41 ± 315.41g. Weight of 8.5% were under 1500 g. The mean gestational age was estimated at 33.64 ± 2.01 weeks. Mean T4 levels were 12.24 ± 1.96 and 12.07 ± 1.95 (p=0.334), and mean TSH levels were 5.34 ± 2.14 and5.15 ± 2.15 (p=0.376) before and after prescribing phenobarbital, respectively. The same results were compared based on sex, gestational age, birth weight, and height for T4 and TSH and T4 based on head circumference. The only significant difference was TSH in preterm infants with head circumference <32 cm before and after prescribing phenobarbital (p=0.030).
Conclusion: In preterm newborns that had less than 2500 g birth weight, phenobarbital did not significantly alter the serum thyroid hormone levels.
Objectives: Anxiety is a significant health issue in mothers who give birth to unhealthy neonates. Different studies have investigated the relationship between anxiety and alpha-amylase. According to the necessity for psychological care of mothers whose infants are hospitalized in intensive care units and consequently the anxiety that is imposed on mothers due to the condition, this study aims to assess anxiety in these mothers and the relationship between this anxiety and salivary alpha-amylase.
Materials & methods: This study was a cross-sectional study conducted at Besat Hospital in Hamadan in 2021. Thirty mothers were enrolled in the study through a census method sampling. The Hamilton questionnaire measured maternal anxiety during the children's hospitalization period. Salivary alpha-amylase samples were taken from all mothers according to the scientific method, and mothers' salivary alpha-amylase levels were measured. All the gathered data were analyzed using SPSS 21 software. The significant level was considered 0.05 in all comparisons.
Results: The mean age of the 30 mothers was 29.27+6.24 years. The mean score of maternal anxiety was 16.27 + 6.78, and the mean salivary amylase level was 33.02 ± 16.22 U / ml. Fourteen mothers obtained low anxiety scores, 14 had moderate anxiety, and two had severe anxiety. No significant relationship was found between the mean of salivary alpha-amylase at the three levels and anxiety. There was no significant relationship between anxiety level with parent location, age, mother's level of education, infant gender, and child rank.
Conclusion: According to the results of the present study, there was no significant relationship between the level of alpha-amylase and the level of anxiety in mothers of neonates admitted to the neonatal intensive care unit (NICU), so further researches in similar groups that are in anxious conditions seem necessary.
Objectives: Sedation and stability during electroencephalography (EEG) in pediatrics have high clinical importance. This study compares the sedative properties of oral chloral hydrate (OCH) and intranasal fentanyl (INF).
Materials & methods: This study was a randomized clinical trial conducted in 2020 in Isfahan City on sixty-two pediatric candidates for EEG. Patients were randomized into two groups receiving 50 mg/kg OCH and 2 μg/kg INF thirty minutes before the process. The heart rate (HR), mean arterial pressure (MAP), respiratory rate (RR), and oxygen saturation (O2 sat) of patients, sedation, and physician's satisfaction were measured and compared between groups.
Results: The HR of patients decreased significantly in both groups (P< 0.001), and the patients that received INF had significantly lower HR 15, 30, 45, and 60 minutes after drug administrations (P< 0.05). RR evaluation indicated significantly decreased RR in both groups (P< 0.001), and patients receiving INF had lower RR 30, 45, and 60 per minutes after drug administrations (P< 0.001). Both groups showed significantly increased sedation levels during the study (P< 0.001), and patients treated with INF had higher sedation levels 15, 30, and 45 minutes after drug administration. Satisfaction rates were higher among the group that received INF (P= 0.020).
Conclusion: The use of INF had significant analgesic and sedative effects on pediatrics undergoing EEG.
Objectives: Given that deficiency in B vitamins can lead to the accumulation of homocysteine (Hcy), and hyperhomocysteinemia may have a role in migraine pathogenesis, the present prospective randomized double-blinded placebo-controlled trial aimed to evaluate the effect of vitamin B-complex supplementation on the alleviation of migraine in children through a possible reduction in Hcy levels.
Materials & methods: Ninety children under 15 years of age suffering from typical migraine were included in the present trial. They were randomly assigned into two groups (forty-five patients in each group) to receive either vitamin B-complex or a matching placebo for six months. Serum Hcy levels and headache characteristics were evaluated and compared before and after administering vitamin B-complex or placebo.
Results: Unlike the placebo group, the monthly headache frequency, severity of headache, headache disability, and serum Hcy levels were significantly decreased after the vitamin administration. The headache duration was not significantly different before and after the treatment. In the vitamin group, there were significant positive correlations between the frequency and severity, frequency and disability, and severity and disability of headaches. Hcy also had significant positive correlations with the frequency and disability of headaches. In the placebo group, the only found significant correlation was between headache frequency and disability.
Conclusion: The administration of vitamin B-complex might effectively relieve migraine severity in children by reducing serum Hcy. However, further studies are needed to confirm the results.
Objective: This study investigates the impact of modified constraint-induced movement therapy (m-CIMT), accompanied by occupation-based and activity analysis, on the participation of children with hemiplegia.
Materials & methods: Twenty-three participants were randomly assigned to the intervention and control groups. The intervention group received occupation-based m-CIMT (m-CIMT along with occupation-based and activity analysis), while the control group received m-CIMT without occupation-based and activity analysis. The intervention was conducted one hour per day, three days a week, for four weeks.
Results: The primary outcomes revealed no significant differences between groups in promoting the participation of children with hemiplegia in the activities of daily living (ADL). However, scores were higher in the intervention group with a medium to large effect size (Canadian occupational performance measure: F(1,19)=2.14, P=0.160, η2P=0.101, Canadian occupational performance measure-satisfaction: F(1,19)=1.53, P=0.231, η2P=0.075, Goal attainment scaling: F(1,19)=5.55, P=0.029, η2P=0.226). This effect remained during the follow-up period. The secondary outcomes indicated no significant differences between groups in improving the manual ability of the children. However, scores were higher in the intervention group with a medium to large effect size (ABILHAND-Kids: F(1,19)=0.64, P=0.434, η2P=0.033, pediatric motor activity log- how long: F(1,19)=3.53, P=0.076, η2P=0.157, pediatric motor activity log- how well: F(1,19)=2.59, P=0.124, η2P=0.120). This effect was sustainable during the follow-up period.
Conclusion: m-CIMT accompanied by occupation-based and activity analysis and the client-centered paradigm substantially enhances the manual ability of children with hemiplegia and their participation in the ADL.
