Driven by the necessity to understand the fire and smoke dispersion characteristics of electric bicycle (escooter) fires and their effects on residents' safety in rural houses, this study was conducted to perform full-scale fire experiments in a village house in Hainan, People's Republic of China. The tested building is a typical multi-story building representative of rural houses in southern China. It is found that an escooter fire grows rapidly once its lithium-ion battery is overcharged to ignite. Inside the stairwell where the escooters are parked, a significant increase in temperature over 60°C across all floors is observed and the maximum temperature reaches up to 800°C on the first floor. Furthermore, the propagation of smoke is fast, reaching the upper floors within 5 minutes and filling the entire building within 7 minutes. Due to stack effect, carbon monoxide concentration is the highest on the fourth floor, notably higher than the other floors. Closing the doors of rooms where occupants are typically present is found to effectively block heat and smoke transfer. Thus, in case an escooter's lithium-ion battery undergoes explosion combustion, it is better that residents stay in rooms by closing or even sealing the doors, waiting for help during most of the fire period. However, in case the lithium-ion battery has not been burning, there still are chances for evacuation or putting out the flame. [ABSTRACT FROM AUTHOR]

The article describes the case of a 49-year old female with an infection mimicking lymphoma in a patient receiving Infliximab for Crohn's disease. It describes the patient's condition following induction of Infliximab that included breathlessness, cough and pustular rash. Also highlighted are the results of the patient's tests that included granulomatous skin lesions and lymphocutaneous nocardiosis.

The article describes the case of a 69-year-old female patient who developed a radiation-induced esophageal stricture nearly two years after completing chemoradiotherapy for mid-esophageal squamous cell carcinoma. Topics discussed include the complications that resulted from the placement of a biodegradable (BD) stent to address the esophageal strictures and the use of balloon dilatation and argon plasma coagulation to alleviate the patient's tissue hyperplasia-related dysphagia.
