Objectives: To study the need of pasteurization of medical equipment and the possibility of production of pasteurizer in Thailand.
Material And Method: The need of pasteurization of medical equipment was studied by a set of questionnaires to heads of the central sterile supply department (CSSD) and head ward nurses in 29 hospitals across Thailand. Efficacy of pasteurization was demonstrated by disinfection with an imported pasteurizer. A pasteurizer was later produced by the researchers and had it tested for efficacy in disinfection.
Results: There were 26 items of medical equipment that could be disinfected by pasteurization. The number of the equipment was 6.2 pieces per bed per week. Disinfection of the equipment was done in C.S.S.D. as well as in patient's wards. The imported pasteurizer was efficacious in disinfection. The pasteurizer made by researchers was convenient for use, not expensive to manufacture and the operating cost for disinfection was 2 to 6 folds less than that done by ethylene oxide gas.
Conclusion: Pasteurization is effective in disinfection and is applicable to certain heat labile medical equipments. A pasteurizer is not difficult to produce, cheap and the operating cost is low. Pasteurization should be more widely applied in Thailand

Department of Otolaryngology, Head and Neck Surgery, Changde Hospital, Xiangya School of Medicine, Central South University (The First People's Hospital of Changde City), Changde 415000, Hunan, China.
Objective: In this study, the research team aimed to explore the therapeutic effectiveness of hyperbaric oxygen therapy (HBOT) for noise-induced hearing loss (NIHL), its influence on patient prognosis, and its impact on hearing to provide valuable clinical evidence.
Methods: Ninety-four patients with NIHL admitted to The First People's Hospital of Changde City, Hunan, China, from May 2021 to January 2023 were selected for this retrospective analysis. Among them, 43 were given conventional treatment (control group) and 51 were given HBOT (observation group).
Background: Noise-induced hearing loss (NIHL) in children is a growing public health concern due to increased exposure to high noise levels in various environments. Early intervention is crucial to prevent long-term developmental and social impacts. This study evaluates the effectiveness of earmuffs as a protective intervention in managing NIHL in children.

Background: Noise sources in paediatric dental offices include machinery and children's cries and screams. Although the presence of occupational noise-induced hearing loss (ONIHL) among dental operators is established, preventive measures such as ear protection devices (EPDs) are not frequently employed as prophylactic intervention. The primary aim of this study was to quantitatively assess the noise levels in paediatric dental clinics and to qualitatively evaluate the operators' perception of noise with and without the use of EPDs.

Introduction: Chest tube insertions (CTIs) have a high complication rate, prompting the training of technical skills in simulated settings. However, assessment tools require validity evidence prior to their implementation. This study aimed to collect validity evidence for assessment of technical skills in CTI on Thiel-embalmed human bodies.
