    Every finding during a neck autopsy may be essential for accurately diagnosing and explaining the mechanism of death. In this prospective study in the Department of Forensic Medicine and Toxicology of Jordan University Hospital, 17 out of 95 neck autopsies revealed contusions of the laryngeal mucosa in the vocal or perivocal area. These contusions were found to be associated with various causes of death, including mechanical asphyxia (such as throttling, ligature strangulation, hanging, smothering, choking, plastic bag asphyxia, gagging, and inhalation of blood) and other causes (such as atypical drowning, carbon monoxide poisoning, head injury due to a road traffic accident, burns, electrocution, and brain edema). This study provides insight into the mechanisms of this important lesion and may contribute to a better understanding of the cause of death.

    This study investigated the permeation resistance of chemical protective gloves made of laminate film comprising nylon, ethylene-vinyl alcohol copolymer (EVOH), and other materials against different chemical substances to examine their usability in different work processes. The permeation resistance of the chemical protective glove was tested using the Japanese Industrial Standards (JIS) test method against twelve substances: acetone, acetonitrile, dichloromethane, ethyl acetate, n-hexane, methanol, tetrahydrofuran, toluene, 2-propanol, 1-butanol, 1,4-diethylene dioxide, and ethanol. After 480 min, no substance, except for methanol and ethanol, permeated at a standard permeation rate of 0.1 μg/cm2/min. Methanol and ethanol showed permeation at 1 min and 30 min elapsed, respectively. Hence, the gloves tested in this study exhibited permeation resistance to various chemical substances, and can thus be used in many work processes. Some film materials have short permeation time against certain chemical substances, but the chemical protective gloves tested in this study can be used at work sites, such as manufacturing sites, that require permeation resistance to different chemical substances.

    Elevated lactate levels are associated with a poor prognosis in patients with sepsis and shock. Intravenous glycerol administration is often used in Japan to treat patients with acute stroke or brain trauma, but such treatment can cause elevated lactate levels. We experienced a case of transient hyperlactatemia induced by intravenous glycerol administration in a patient with brain trauma. A 74-year-old woman underwent decompressive craniotomy because of loss of consciousness and brain edema. Glycerol was administered after the operation for management of the brain edema. Although the patient’s hemodynamics remained stable, her lactate level decreased and increased repeatedly. We recognized that the elevation in her lactate level was associated with the administration of intravenous glycerol. This case suggests that intravenous glycerol administration can induce transient hyperlactatemia.

    Neuroendocrine prostate cancer (NEPC) is a histological variant of prostate cancer and is characterized by aggressiveness and poor clinical outcomes. NEPC usually develops as a mechanism of treatment resistance in patients receiving hormone therapy for advanced prostate cancer. NEPC is sensitive to primary platinum-based chemotherapy, and has a short response duration. Second-line therapy is required in many cases, but clinical data on subsequent treatment after progression to first-line chemotherapy is limited. Here we report our experience of four cases of NEPC treated with second-line chemotherapy. Progression-free and overall survival rates were very low in three of the patients. One patient received multidisciplinary therapy using systemic and local chemotherapy and radiation therapy and survived for 24 months after initiation of second-line chemotherapy. Multidisciplinary therapy with chemotherapy and radiation is a promising option for improving the survival of patients with NEPC.

    Tarsal tunnel syndrome (TTS) is a nerve entrapment of the posterior tibial nerve. This uncommon condition frequently goes undiagnosed or misdiagnosed even though it interferes with the daily activities of workers. Here we discuss the return to work status of a 37-year-old male patient who manages a manufacturing plant. He was identified as having Tarsal Tunnel Syndrome as a result of a foot abnormality and improper shoe wear. He had moderate pes planus and underwent tarsal tunnel release on his right foot. What are the determinant factors in defining a patient’s status for returning to work after a tarsal tunnel release? We conducted a literature review using PubMed, Science Direct, and Cochrane. The Indonesian Occupational Medicine Association used the seven-step return-to-work assessment as a protocol to avoid overlooking the process. Duration of symptoms, associated pathology, and the presence of structural foot problems or a space-occupying lesion are factors affecting outcome. Post-operative foot scores, including Maryland Foot Score (MFS), VAS, and Foot Function Index, can be used to evaluate patient outcomes. Early disability limitation and a thorough return-to-work assessment are needed.

    Robotic-assisted surgery enables precise manipulations with magnified vision, stereoscopic vision, and forceps with multi-joint functions. It requires unique procedures such as position setting, port placement, roll-in, and docking, which lead to prolonged operation and anesthesia time. Five conditions described below were established at our institution to reduce the time to the initiation of console: (1) changing the patients’ position from the flat lithotomy position to the spread legs position; (2) attaching a Hasson cone to hold the umbilical cannula stable; (3) changing the cannula’s obturator (inner tube) from blunt to bladeless; (4) fixing the team, and (5) conducting regular docking training. These outcomes were examined in this study. The study included 77 patients who underwent robotic-assisted total hysterectomy for benign uterine disease and stage IA uterine cancer at our individual institution between April 2019 and July 2022. We compared the median time from anesthesia to console initiation between the first half group (cases 1-40) and the second half group (cases 41-77). The former required 91.5 (53-131) minutes, whereas the latter required 59 (37-126) minutes. Appropriate equipment selection and team education can reduce the time to console initiation.

    Adenocarcinoma, HPV-independent, mesonephric type (hereafter referred to as “mesonephric carcinoma”) arising from the cervix is rare, its treatment has not been established, and its sensitivity to chemotherapy has not been fully investigated. Here we report on a 30-year-old female patient who presented at our hospital with a chief complaint of abnormal genital bleeding. We suspected cervical cancer. Based on examination, biopsy, and imaging, she was diagnosed with stage IIA2 adenocarcinoma of the cervix and was scheduled for surgery. Because she had a SARS-COV-2 infection, she was given two courses of paclitaxel-carboplatin (TC) therapy, based on the then-current surgical risk assessment after SARS-COV-2 infection, with a waiting period of at least 8 weeks. The patient was deemed to have a partial response and was treated with paclitaxel and carboplatin, after which she was deemed to have a partial response and underwent total hysterectomy. A diagnosis of stage IIA2 mesonephric carcinoma, ypT1b2N0M0, was made after histopathologic examination of an excised specimen. The patient was treated with 4 additional courses of TC therapy after surgery, and has had no recurrence in 13 months. We report a first case of response to neoadjuvant chemotherapy with TC regimen in a patient with mesonephric carcinoma of the cervix.

    Digital and technological solutions constitute a key enabler to achieving better workplace safety and health outcomes. Fundamentally, the success of their implementation is underscored by a need for employers, employees, industry stakeholders and policymakers to collaborate in adopting a “digital first” mindset. This review provides a background on the evolution of work and the workforce in post-independence Singapore, and introduces pertinent local workplace safety and health trends. It delves into how a “digital first” approach may be adopted and effected, followed by challenges and opportunities in the digitalization of Singapore’s workplace safety and health landscape. Illustrative examples are used to highlight applications of digital and technological solutions in the control of occupational hazards. In our discussion, workplace strategies are built around the hierarchy of controls framework, whereas worker-related strategies are divided into workspace optimization for productivity/performance enhancement, training/education, and instituting surveillance/open reporting mechanisms. We demonstrate that with an open and forward-looking mind, and well-executed change management, we will be able to capitalize on technological advances to improve work and working conditions for all workers.

    The exact definition of a personal health record (PHR) is not clear, but it is generally defined as an electronic record of an individual’s medical examination results and medication history that can be accurately tracked by the individual and family members. There are many opportunities to obtain personal PHR data in the field of occupational health, and the amount of information in a worker’s PHR is enormous. It is necessary in this field to comprehensively integrate and accumulate not only information from medical examinations, but also records of the work environment and work records as personal health information.

    The population of people in Japan over 65 years old is expected to exceed 30% by 2025. As the society ages, there are not only healthy workers and employers, but also an increasing number of diseased or injured workers. Falls, the most common occupational hazard, increase in incidence with age. The management of osteoporosis and prevention of bone fractures from falls are emerging in elderly female workers, to reduce the loss of work productivity. Rheumatoid arthritis is a representative musculoskeletal disease that causes functional decline because of joint damage mainly in working women, but appropriate treatment improves disease activity and work productivity in workers with rheumatoid arthritis. It is also important not only to digitize subjective information by converting it into digital form (digitization), but also to digitalize the physiological information related to health, labor and disease (digitalization). In the future, artificial intelligence (AI) will be able to analyze vast amounts of physiological information (big data) obtained from workers and patients via the Internet of things (IoT), which will improve the information value linked to health promotion and optimal treatment practices, and contribute to the Digital transformation (DX).

    This paper discusses the role of the workplace in digital occupational health as part of an increasingly digitalized working life. Digital occupational health can be considered to consist of at least the following digitalized components: a) occupational health services and data, b) human resource data, c) group-level field data collected from the work environment and employees, and d) individual-level field data collected for personal use only. These data and related processes form a basis for so called data-driven management of occupational health and safety. To collect such data and keep it updated, it is important to pay attention to: a) worker acceptance, b) user friendliness, c) data validity, integrity, and protection, d) adequate resources, and e) ethical and effective use of the data. The current literature suggests that there are promising mobile and wearable devices and eHealth solutions to support worker health. To use them effectively, it is good to pay attention to the implementation process in the workplace. Ultimately, trust and collaboration among all parties are the cornerstones for gaining benefits from digital occupational health.

    Stress is a common part of working life, but knowledge is lacking on how to identify it early and with little effort on the part of the employee. We investigated whether simple stress reports and computer usage data could be useful tools for long-term assessment of stress in real life. 38 experts responded to a baseline questionnaire on need for recovery (NFR) and psychological distress (General Health Questionnaire, GHQ12). Their computer usage for work was recorded for 5 months, during which they filled in a 4-month simple diary and a 2-week detailed diary on, for example, stress and productivity. Salivary cortisol and heart rate variability were collected on 3 consecutive days. Generalized estimating equations models were used for the analyses. High NFR and GHQ12 predicted self-reported stress during work, and a decrease in (some) mouse usage features, but not keyboard usage features, over the following months. Some mouse usage features were associated with stress and productivity. The results provide some support for the usefulness of simple stress questions and mouse usage features in assessing long-term stress in real life.

    There is clear scientific evidence that physical activity helps to prevent depression and anxiety. Utilizing mobile health (mHealth) technologies to enable physical activity is promising, but the evidence of the effectiveness of mHealth interventions on physical activity and mental health is inconsistent. We recently developed a native smartphone app to prevent depression and anxiety by promoting physical activity. One of the app’s strengths is that it adopts a deep-learning model and automatically estimates psychological distress from users’ physical activity patterns. We conducted a single-arm, 1-month feasibility trial to examine the implementation of the app and its effectiveness in promoting physical activity and improving depression and anxiety. As a result, we did not observe any significant improvement in physical activity or psychological distress. For implementation aspects, the participants used the app less. The conclusion of the presentation is that mHealth interventions are promising for the improvement of physical activity and mental health among workers, but, at this stage, their effectiveness is unclear. There are challenges to be addressed, especially in implementation.
