[A Case of Spontaneous Rupture of Chromophobe Renal Cell Carcinoma].

Spontaneous rupture of renal cell carcinoma (RCC) occurs in 0.3-0.6% of all RCC cases.

Simple prediction tools for disease progression in unvaccinated patients with mild/moderate COVID-19 aged under 65 years: Simplified DOATS and DOAT scores.

DOATS score and DOAT score, COVID-19 progression prediction tools we have developed, utilize clinical information such as presence of diabetes/obesity (DO), age (A), body temperature (T), and oxygen saturation (S). They showed good predictive power, but their scoring calculation was slightly complex, leading us to develop simplified versions. This report discusses the ability of the simplified versions to assess deterioration risk in unvaccinated, mild/moderate COVID-19 patients aged <65 years.

[Introduction of Support for Thoracoscopic Surgery by Clinical Engineers:Task Shift as Scopist by Clinical Engineers].

On October 1, 2021, the Clinical Engineer Law was revised and expanded the task of clinical engineers (CEs). After that, they can hold and operate a endoscope in endoscopic surgery. On June 9, 2022, our hospital asked CEs to directly participate in thoracoscopic pleural biopsy as scopist( scope operator) for the first time, and since then, a total of 54 thoracoscopic surgery cases were performed by CEs as scopist over the course of one year.

External validation of the CHOKAI score for the prediction of ureteral stones: A multicenter prospective observational study.

Objective: The CHOKAI and STONE scores are clinical prediction rules to predict ureteral stones in patients presenting with renal colic. Both systems contribute to reducing diagnostic radiation exposure; however, few studies have compared the two scoring systems. Therefore, we aimed to compare these systems and assess their diagnostic accuracy for ureteral stones.

[Complete Transection of the Cervical Trachea Caused by Chest Blunt Trauma].

A 52-year-old man was injured when driving through the gate by a motorcycle without noticing the rope between the gateposts. He developed hoarseness, subcutaneous emphysema and dyspnea, and was transferred to our hospital by an ambulance. Chest X-ray and computed tomography showed subcutaneous and mediastinal emphysema, and complete transection of the cervical trachea.

[Penetrating Injury of the Lung with a Glass Splinter].

A 62-year-old man got drunk and dived into the windowpane. He received lacerations on his face and incised wound at his right chest, and was carried to our hospital. Computed tomography showed a glass splinter, about 14 cm of length, in the chest cavity.

[Micropapillary component in lung adenocarcinoma generated in emphysema].

We report a case of 72-year-old male of adenocarcinoma with micropapillary component of the lung. Though the hilar lymph node metastasis was eminent, primary site was difficult to identify by using computed tomography (CT). SUV max with positron emission (PET)-CT in the case suggested the lung cancer in the emphysematous lung and it became an operation.
