ABSTRACT

OBJECTIVE: To assess the current management of pediatric epileptic seizures in non-hospital settings and the efficacy of early therapeutic intervention with rescue medication in Japan. METHODS: This descriptive cross-sectional study was based on an online survey of caregivers of pediatric patients with epilepsy. The survey consisted of questions regarding seizure frequency and symptoms, the use of rescue medication, and emergency medical care. Statistical analyses were performed to evaluate the association between the time to rescue medication administration and seizure resolution. RESULTS: Responses were obtained from 1147 caregivers of pediatric patients with epilepsy. Of the patients described in the study, 98.5 % had been prescribed anti-seizure medication, 95.3 % had more than a few seizures per year, and 90.3 % used rescue medication. The time to seizure resolution was significantly reduced when rescue medication was administered early. Overall, 28.4 % of the patients required emergency transport to hospital, which increased disruption to the lives of caregivers, who returned to their normal activities after an average of 17.2 h. CONCLUSION: Emergency transport of patients places a significant burden on caregivers. Earlier administration of rescue medications is associated with a reduction in the need for emergency room visits, which reduces the burden on the patient as well as the caregiver.

ABSTRACT

Summary: There are very few reports of syndrome of inappropriate antidiuresis hormone secretion (SIADH) after receiving severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccine. Herein, we present the case of an 84-year-old woman who developed severe hyponatremia following the second administration of the SARS-CoV-2 mRNA vaccine. The patient presented with nausea, vomiting, and headache. Laboratory tests showed a plasma sodium level of 119 mmol/L. After receiving 500 mL of intravenous saline over a 2-h period, her plasma sodium level raised to 121 mmol/L, but her symptoms persisted. Considering that rapid plasma sodium correction was necessary, we started 3% saline solution overnight. Her plasma sodium level raised to 132 mmol/L and her symptoms completely resolved. Clinical and laboratory findings were consistent with a diagnosis of SIADH. In the absence of any other triggering factors, we concluded that the condition was likely associated with the vaccination. Clinicians should be aware of the potential for hyponatremia, particularly SIADH, associated with SARS-CoV-2 mRNA vaccination. Learning points: Reports of syndrome of inappropriate antidiuresis hormone secretion after receiving severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination are limited. If nausea, headache, and confusion are observed immediately after SARS-CoV-2 vaccination, clinicians should consider the presence of hyponatremia. As similar case reports to date have presented with severe hyponatremia, prompt treatment may be required.

ABSTRACT

A 71-year-old woman with a four-year history of chronic lymphocytic leukemia (CLL) received ibrutinib as initial treatment due to progressive anemia and thrombocytopenia. Eleven months after the start of the treatments, although her cytopenia had ameliorated, she developed classic Hodgkin lymphoma, a rare form of Richter's transformation. She was successfully treated with two courses of adriamycin, vinblastin, bleomycin and dacarbazine followed by radiotherapy. In general, several clinical, genetic and molecular factors are associated with Richter's transformation. In addition, our present case suggested that ibrutinib could be a potential risk factor for Richter's transformation in CLL patients.

ABSTRACT

A chemiluminescence system, Milliflex Quantum (MFQ), to detect microcolonies, has been used in the pharmaceutical field. In this study, we investigated aquatic bacteria in hemodialysis solutions sampled from bioburden areas in 4 dialysis faculties. Using MFQ, microcolonies could be detected after a short incubation period. The colony count detected with MFQ after a 48-hour incubation was 92% ± 39%, compared to that after the conventionally used 7-14-day incubation period; in addition, the results also showed a linear correlation. Moreover, MFQ-based analysis allowed the visualization of damaged cells and of the high density due to the excessive amount of bacteria. These results suggested that MFQ had adequate sensitivity to detect microbacteria in dialysis solutions, and it was useful for validating the conditions of conventional culture methods.

ABSTRACT

We obtained the scanning tunneling spectrum (STS) of an electron confined in a rectangular quantum corral by considering the electron to be in a quasi-stationary state. Because of non-hermiticity of the Hamiltonian, the electron has a complex eigenenergy. The imaginary part gives the peak width coming mainly from the electron tunneling through a corral barrier. Our STS is consistent with the experimental spectrum that had been measured for electrons confined in a rectangular quantum corral. We obtained peak widths against energy levels and components of the STS which are constructed with quasi-stationary eigenstates. It is shown that normalization of a wavefunction by considering its time evolution is decisive in obtaining the proper STS. Moreover, we specified the position dependence of STS in relation to the image of the surface local density of states.

ABSTRACT

Mouse parthenogenetic embryos (PEs) are developmentally arrested until embryo day (E) 9.5 because of genomic imprinting. However, we have shown that embryos containing genomes from non-growing (ng) and fully grown (fg) oocytes, i.e. ng(wt)/fg(wt) PE (wt, wild type), developed to E13.5. Moreover, parthenogenetic development could be extended to term by further regulation of Igf2 and H19 expression using mice with deletion of the H19 transcription unit (H19Delta13) together with its differentially unit (DMR). To gain an insight into the extended development of the parthenotes to term, we have here investigated the expression levels of paternally imprinted genes in ng(H19Delta13)/fg(wt) PE throughout their development. In ng(H19Delta13)/fg(wt) Pes that died soon after recovery, the expression of Igf2 and H19 was restored to the appropriate levels except for low Igf2 expression in the liver after E15.5. Further, the paternally expressed Dlk1 and Dio3 were repressed, while the expression levels of the maternal Gtl2 and Mirg were twice those of the controls. However, the above-mentioned four genes showed almost normal expression in the surviving ng(H19Delta13)/fg(wt) PEs. The methylation analysis revealed that the intragenic DMR of the Dlk1-Gtl2 domain was hypermethylated in the ng(H19Delta13)/fg(wt) PEs that survived, but not in the PEs that died soon after recovery. The present study suggests that two sets of co-ordinately regulated but oppositely expressed genes, Igf2-H19 and Dlk1-Gtl2, act as a critical barrier to parthenogenetic development in order to render a paternal contribution obligatory for descendants in mammals.
