Fournier gangrene (FG) is a rare life-threatening infection j that can occasionally extend beyond the perineum into the retroperitoneal space. Preperitoneal involvement in female patients is extremely rare. We report a unique case of a 59-year-old female with FG, characterized by atypical preperitoneal extension. Despite initial treatment failure, the patient recovered following emergency debridement, and targeted antibiotic therapy. This case underscores the importance of early diagnosis, timely surgical intervention, and multidisciplinary care in managing atypical FG presentations in female patients. It emphasizes the need for prompt and aggressive management to improve survival in these rare instances.

Ectopic kidney is a rare congenital anomaly which occurs in approximately 1 in 1,000 live births. Intrathoracic kidney is the rarest type of the ectopic kidney, which constitutes < 5% of all ectopic kidney cases. It is often associated with congenital diaphragmatic hernia, which can cause severe respiratory distress. However, most patients with intrathoracic kidney are asymptomatic, and incidentally diagnosed with prenatal ultrasonography or chest radiography after birth as intrathoracic mass-like lesion. In this study, we report a case of an asymptomatic neonate with intrathoracic kidney. An intrathoracic mass was detected in plain chest radiography of a 17-day-old boy, and it was identified as the right kidney in the thoracic cavity by computed tomography and ultrasonography.Correction of the ectopic kidney and repair of diaphragmatic hernia were successful at the age of 52 days. After the operation, the right kidney was normally detected in the right renal fossa, and there was no recurrence of diaphragmatic hernia. To the best of our knowledge, the present case is the only reported case of intrathoracic kidney at the neonatal period, in South Korea. Careful review of chest radiography at the neonatal period and clinical suspicion of rare diseases like herniation of intraabdominal organ are needed.

Purpose: Hand-foot syndrome (HFS) and hand-foot skin reaction (HFSR) are relatively common toxicities that interfere with the quality of life (QoL) of patients with cancer. Anti-inflammatory tripeptide cream (ATPC) is a complex formulation of anti-inflammatory tripeptides, the CD99-agonist Binterin and the Wnt-antagonist Winhibin. The present study aimed to assess the therapeutic effects of ATPC in HFS/HFSR associated with anticancer drugs. Materials and Methods: This was a single-center, randomized, double-blind, placebo-controlled trial. Patients who developed grade 1 HFS/HFSR after systemic anticancer treatments were enrolled, and randomly assigned to receive either ATPC or placebo cream (PC) and followed up at 3-week intervals for up to 9 weeks. Primary endpoint was the development of grade ≥ 2 HFS/HFSR. Results: Between April 2019 and July 2022, 60 patients (31 in the ATPC and 29 in the PC group) completed the study. The incidence of grade ≥ 2 HFS/HFSR was significantly lower in the ATPC than in the PC group (25.8% vs. 51.7%, p=0.039). The ATPC showed trends towards a better QoL score, assessed by a HFSR and QoL questionnaire at 9 weeks (26.0 vs. 29.9, p=0.574), and a lower frequency of discontinuation, interruption, or dose reduction of anticancer drugs (51.6% vs. 58.6%, p=0.586) than the PC group over 9 weeks, though without statistical significance. Conclusion Our results showed that ATPC significantly decreased the development of grade ≥ 2 HFS/HFSR in patients already with HFS/HFSR. Therefore, ATPC may be an effective treatment for HFS/HFSR associated with anticancer drugs.

Pure-tone audiometry, using an audiometer, is the fundamental hearing test for diagnosing hearing loss. The requirements of the devices and the detailed process for calibrating the related equipment are described in international standards. However, traceable calibration and uncertainty evaluation processes are not widely accepted or applied to the qualification and maintenance of audiometric equipment. Here, we briefly review standard measurement systems for audiometric devices and introduce their calibration procedures. The uncertainty of each calibration process was investigated, and its impact on hearing test results was considered. Our findings show that the traceability of each procedure can be secured, satisfying the uncertainty requirement and being sufficiently smaller than the permissible deviation from the audiometer requirement. To guarantee the objectivity and reliability of hearing tests and maintain low uncertainty, close cooperation and mutual understanding between the metrology field and the medical community are necessary.
