Background: Xanthogranulomatous inflammation of the female reproductive organs is a rare chronic inflammation. In most reported cases, the lesion was limited to the endometrium and fallopian tubes. Here, we report two cases of xanthogranulomatous inflammation of the myometrium with a history of endometrial biopsy. Case Reports: In two cases, myometrial xanthogranulomatous inflammation destroyed the myometrium. This inflammation developed into surrounding pelvic organs, resulting in uterine perforation. Conclusion: When inflammatory lesions are found after intrauterine manipulation, the possibility of developing xanthogranulomatous inflammation should be considered. If antibiotics are ineffective, prompt surgical treatment is necessary.

It is important to estimate the current magnitude and charge amount of a partial discharge (PD) in a gasinsulatedswitchgear (GIS). In this study, electromagnetic fields generated by a PD in an 84 kV-class three-phase GIS fortesting have been measured with a voltage probe installed on the outer surface of an insulation spacer of the GIS tank,and the corresponding simulations have been carried out using the three-dimensional finite-difference time-domain(FDTD) method. FDTD-computed time-domain voltages across spacers agree reasonably well with the correspondingmeasured ones, and the current magnitude of PD and its charge amount have been estimated.

Esophageal diverticula are rare conditions that cause esophageal symptoms, such as dysphagia, regurgitation, and chest pain. They are classified according to their location and characteristic pathophysiology into three types: epiphrenic diverticulum, Zenker's diverticulum, and Rokitansky diverticulum. The former two disorders take the form of protrusions, and symptomatic cases require interventional treatment. However, the esophageal anatomy presents distinct challenges to surgical resection of the diverticulum, particularly when it is located closer to the oral orifice. Since the condition itself is not malignant,minimally invasive endoscopic approaches have been developed with a focus on alleviation of symptoms. Several types of endoscopic devices and techniques are currently employed, including peroral endoscopic myotomy(POEM). However,the use of minimally invasive endoscopic approaches, like POEM, has allowed the development of new disorder called iatrogenic esophageal diverticula. In this paper, we review the pathophysiology of each type of diverticulum and the current state-of-the-art treatment based on our experience.
