Background: Sodium valproate is an antiepileptic drug primarily used to treat status epilepticus [SE]; however, its effect on cardiac function is unclear. This study aimed to examine the effect of 6 months of sodium valproate treatment on the cardiac index in new cases with status epilepticus. Methods: In this cross-sectional study, 30 cases with status epilepticus [18 boys and 12 girls] who were admitted to the Pediatric Intensive Care Unit of Hazrat-e Rasool Hospital were enrolled. Information on basic demographic and clinical data of all children, such as age, weight, gender, blood pressures, and underlying diseases, was recorded. Echocardiography and electrocardiogram [ECG] were performed for all cases before and after the treatment. Results: There were no abnormalities in ECG parameters [including PR, QRS, and QT intervals] after 6 months of treatment with sodium valproate. No significant differences were found in echocardiographic parameters, including blood pressure, pulmonary artery pressure [PAP], right ventricular [RV] size, diastolic dysfunction,], Tie index, end-diastolic volume [EDV], ejection fraction [EF], and TAPSE before and after study [p>0.05]. Conclusion: Administration of sodium valproate over 6 months is not associated with a serious adverse effect on heart function in children with status epilepticus.

Improving the energy efficiency of fish culture has always been a concern for warm‐water fish farming units. In this respect, the present study explored energy consumption flow and energy indices of warm‐water fish production in Guilan province, northern Iran. The impact of the energy equivalent of the system inputs on the energy equivalent of fish yield was modeled by the Cobb–Douglas function. The results revealed that total energy input, energy ratio, energy productivity, and energy intensity were 3710.4 MJ per 100 m2, 0.042, 0.009 kg MJ−1, and 109.77 MJ kg−1, respectively. Feed, electricity, and fossil fuel were the most energy‐intensive inputs accounting for 70.09%, 11.95%, and 11.70% of total energy use, respectively; representing the dominant role of feed in the energy input of warm‐water fish farming. Renewable and nonrenewable energy resources accounted for 6.97% and 93.03% of the total energy input of warm‐water fish culture system, respectively; requiring more care to cut the share of nonrenewable energy inputs. The Pareto chart determined that fingerling, labor, and electricity had the highest effects on the warm‐water fish yield. Therefore, more attention should be paid to the appropriate use of these inputs in warm‐water fish culture in the study region.

Background: Pulmonary arterial hypertension (PAH) is a common disorder in preterm neonates caused by patent ductus arteriosus (PDA). Although both sildenafil and bosentan have been shown to improve PAH, there is no study to compare the effect of these drugs in improving preterm infants with hemodynamically significant PDA and PAH. This study aimed to compare the therapeutic efficacy, safety, and possible side effects of combined therapies with Apotel + Bosentan, Apotel + Sildenafil, and Apotel alone in treating PDA and PAH in preterm infants. Methods: This clinical trial was conducted on 150 preterm neonates with PDA and PAH. Neonates were then divided into three groups and orally administrated with Apotel alone (10 mg/kg), Apotel (10 mg/kg) + Sildenafil (1 mg/kg), and Apotel (10 mg/kg) + Bosentan (1 mg/kg). Echocardiographic examination was performed before and 72h after the intervention. Results: Treatments with Apotel, Apotel + sildenafil, and Apotel + bosentan significantly decreased the mean of RV1, RV2, RV3, RVEDA, RVESA, RV/LV, TR intensity, TR PG, PI PG, and MPA diameter compared to before intervention (p<0.01). The mean of TAPSE after Apotel, Apotel + sildenafil, and Apotel + Bosentan administrations was significantly increased compared to before the study, indicating improvement in RV performance (p<0.01). The frequency of BPD and ROP in Apotel group (7.7% and 19.2%, respectively) was significantly lower than that in Apotel + sildenafil group (30% and 45%, respectively) and Apotel + bosentan (25% and 40%, respectively) groups (p<0.05). Conclusion: Oral administration of sildenafil and bosentan improved cardiac index beside its side effects in preterm infants PAH and PDA. Future clinical trial studies with larger sample sizes and long-term follow-up on term or near term neonates are recommended. Trial registration: IR.IUMS.FMD.REC.1399.430

Background: The tendency of developing malignancy in patients with congenital heart defects has been well documented. Osteosarcoma and tetralogy of Fallot (TOF) have never been so far reported to happen in a single patient. Case Report: An 8.5-year-old boy with history of repaired tetralogy of Fallot (TOF) one year back presented with refractory leg pain most frequently at nights. CT scan, bone scan and bone biopsy of the proximal part of the left fibula revealed: high grade intramedullary osteogenic sarcoma (OS) of osteochondroblastic type. Conclusion: According to latest genetic studies TOF and OS don't share any common genetic background; it would be interesting for clinicians to have in mind such tendency between TOF and OS to investigate if they share any origin genetically or developmentally?
