Background: The well-being of disaster responders is just as important as that of disaster victims as maintaining responders’ health is essential for the effective disaster response. This study aimed to identify the key factors contributing to fatigue in disaster responders. Methods: This cross-sectional study analyzed data from disaster responders deployed during the 2024 Noto Peninsula Earthquake in Ishikawa prefecture, Japan. Data were collected using the health management version of the Japanese Surveillance in Post-Extreme Emergencies and Disasters app from January to March 2024. Associations between contributing factors including problems in the work environment, type of work activity, and occupation, and self-reported fatigue score were examined using the t-tests, analysis of variance, and multivariable regression analysis. Results: We analyzed 15,067 data entries from disaster responders. Fatigue levels among disaster responders were generally low, with 73.7% of scores between 1 and 3 during the first phase and 82.3% during the second phase. Fatigue was significantly higher in the early response phase (β = 0.32, 95% confidence interval [CI]: 0.27—0.37) and among logisticians (β = 0.23, 95% CI: 0.18—0.28) and Health Emergency Operations Center staff (β = 0.20, 95% CI: 0.14—0.25) than among nonlogisticians and non —Health Emergency Operations Center staff members. Problems in the work environment had the largest effects: inability to take meals and breaks increased fatigue by 1.82 points (95% CI: 1.56—2.07), and unclear tasks or command structures by 0.82 points (95% CI: 0.57—1.06). Conclusion This study underscores the importance of establishing a structured command system, strengthening responder training and improving working conditions to safeguard responder well-being.

Eosinophilic cystitis is a rare form of allergic cystitis. We reported a case of eosinophilic cystitis coexisting with superficial bladder cancer, which seemed to be invasive bladder cancer on imaging. We performed total cystectomy in this case. When invasive bladder cancer is diagnosed by imaging, coexistence of eosinophilic cystitis with superficial bladder cancer should be considered if biopsy does not show invasive bladder cancer.

If the traumas treated at Ishiuchi Clinic of Showa University during the past 31 years from 1957 to 1988 are classified by topical site and type, the traumas in the knee and ankle joints are seen in many cases, occupying totally 53% of the total traumas. Compared with these, the traumas in the hip joint are relatively rare, and particularly, the cases of traumatic dislocation of the hip joint are extremely rare articular traumas. The subject cases were 6 males and 5 females.
The traumatic mechanisms have been elucidated, and concurrently, super selective angiography was performed on the medial circumflex arteries in 8 cases to determine angiographically the time when loading began.
There are many cases whose posterior dislocations were presumably caused by a mechanism that, while the tibia is fixed by skiing boots in a position including forward in angles slightly wider than 90°, flexion and rotary strengths applied to the hip joint are much strong at the skier's position with extended knee joint because the safety binding does not come loose at the fall of the body forward.
The superior retinacular arteries are said to be very important remification of the medial circumflex femoral artery which supplies 2/3-3/4 of blood stream to the outside of the loaded epiphysial region. What are presumed as the causes for the ineffective and defective angiograms are (1) compression by hematoma, (2) extended SRA and (3) rupture of SRA. The time of loading to begin was found as 2 months in the case with favorable angiograms of SRA and 4 months in the cases with ineffective or defective angiogram.
