    Abstract Junctional ectopic tachycardia (JET) is a relatively uncommon arrhythmia predominantly observed in infancy, often occurring after congenital heart surgery. Although JET is rare in adults, it can occur in the presence of myocardial ischaemia. We describe a woman in her early 70s who presented with multivessel ST-segment elevation myocardial infarction and underwent percutaneous coronary intervention on left anterior descending artery and right coronary artery. She developed JET on the second day, resulting in haemodynamic compromise. Despite initial treatment attempts including amiodarone and beta-blocking agents proving insufficient in controlling JET, we successfully managed by administering ivabradine. Subsequently, she was discharged with recovered cardiac function without recurrence of JET. JET often proves refractory to multiple antiarrhythmic agents and can lead to unfavourable outcomes. Several case reports have demonstrated the effectiveness of ivabradine in treating JET during infancy, which can also be an effective therapeutic option for adult without adversely affecting haemodynamics.

    Abstract Growth spurts of the bone occur during infancy(1 to 4 years)and puberty(12 to 17 years). While, generally, pubertal spurts appear to draw more attention than infantile spurts, the latter constitute maximum growth spurts. Indeed, those during the first year of life lead to a 1.5-fold increase in height or a height increase of 25 cm, thus representing the greatest of all growth spurts that occur in humans during their lifetimes. Again, while height growth continues through the first 3 years of life, nutrition represents the single greatest contributing factor to height growth during this period. Again, while, as with other organ primordia, the bone primordium is formed during the organogenesis stage, calcification becomes most active during the third trimester of pregnancy. Thus, this review provides an overview of bone growth in humans, in relation to bone/calcium metabolism, which begins in the fetal stage before birth and continues through infancy and puberty, finally leading to attainment of peak bone mass in humans.

    Abstract We propose a stochastic process of interacting many agents, which is inspired by rank-based supplanting dynamics commonly observed in a group of Japanese macaques. In order to characterize the breaking of permutation symmetry with respect to agents' rank in the stochastic process, we introduce a rank-dependent quantity, overlap centrality, which quantifies how often a given agent overlaps with the other agents. We give a sufficient condition in a wide class of the models such that overlap centrality shows perfect correlation in terms of the agents' rank in the zero-supplanting limit. We also discuss a singularity of the correlation in the case of interaction induced by a Potts energy.

    Abstract Lymphomatoid granulomatosis (LYG) is a rare B cell lymphoproliferative disorder associated with Epstein-Barr virus infection. LYG diagnosis is often difficult because of non-specific and varied radiological and pathological findings. The lung is the most common organ of LYG occurrence, but extrapulmonary lesions involving the central nervous system, skin, kidneys and liver are observed. A surgical biopsy is often inevitable for LYG diagnosis.We encountered a man in his 50s who presented with progressive dyspnoea. Extrapulmonary lesions were not observed. Although he developed respiratory failure within a short period, a low dose of corticosteroid relieved his symptoms. Video-assisted thoracoscopic lung biopsy revealed grade 1 LYG. The patient was successfully treated with chemotherapy, including rituximab. Only a few cases of LYG with progressive respiratory failure are reported, and most have been diagnosed via autopsy. Our case highlights the importance of performing a surgical lung biopsy at the appropriate time to diagnose LYG.

    Abstract Purpose: The analysis of water-soluble herbicides, including glyphosate (Glyp), glufosinate (Gluf), paraquat (PQ), and diquat (DQ), is time-consuming and expensive because they cannot be analyzed using general toxicological screening methods. Thus, this study aimed to develop a simple and rapid method to simultaneously analyze these compounds without any derivatization nor ion-pairing reagents.
    Methods: The analytes were separated using hydrophilic interaction liquid chromatography and detected using tandem mass spectrometry. The developed method was applied to plant and biological samples assuming criminal damage and poisoning cases, respectively.
    Results: All analytes were separated well and detected with good peak shapes. For plant samples, the herbicides were specifically detected from withered leaves using a simple extraction method. For biological samples, quantitative analysis was successfully validated, and the limit of quantification values of Glyp and Gluf were 0.2 µg/mL, and those of PQ and DQ were 1 ng/mL.
    Conclusion: The developed method had sufficient performance for practical forensic applications including poisoning cases and malicious uses to damage commercial crops.

    Abstract Rheumatoid meningitis is a rare neurological manifestation that is difficult to diagnose. Here we report a 77-year-old woman who developed a left hemiparesis because of an arachnoid cyst with rheumatoid meningitis. The patient had a 13 year history of rheumatoid arthritis, which had been successfully treated. She developed left hemiparesis and visited our hospital. MRI showed a high signal intensity lesion in the right frontal subarachnoid space and an arachnoid cyst on Fluid attenuated inversion recovery (FLAIR). A gadolinium enhanced T1 weighted image revealed associated abnormal enhancement. We removed the arachnoid cyst and diagnosed the patient as having rheumatoid meningitis. Her symptoms and MRI findings improved rapidly by methylprednisolone pulse therapy. Rheumatoid meningitis is rare, but a case of arachnoid cyst associated with rheumatoid meningitis was extremely rare. This is the first report of such a case.
