    The rate of incidence of Tuberculosis (TB) in Indonesia is the ninth highest in the world. Poor environmental conditions, mainly related to air circulation and improper behaviour, were recognized as the risk factors in this country. A case-control study of 69 participants was conducted in the Umbulharjo I Public Health Centre of Yogyakarta during January-August 2019. Data collection was conducted using a tested questionnaire. Analysis was performed using Chi-square and Logistic regression. Three variables were identified as potential risk factors for TB: family history of TB, smoking behaviour, and ventilation condition. The results of the logistic regression test revealed that people who smoke have the greatest risk of TB infection. Health promotion needs to be enforced to educate both patients and their family to prevent the transmission of TB.

    Although acute organophosphate (OP) pesticide poisoning is associated with the risk cardiovascular diseases (CVD), the association between chronic occupational OP pesticide exposure and CVD risk is limited. We investigated serum high-sensitivity C-reactive protein (hs-CRP) levels and QTc intervals in 45 agricultural workers who were chronically exposed to OP pesticides and 45 non-exposed subjects. Serum hs-CRP level was determined by enzyme-linked immunosorbent assay (ELISA) and a level >1.0 mg/l was regarded as CVD risk. The QT interval was measured by routine 12-lead Electrocardiogram (ECG) with Lead II rhythm, and QTc was calculated. The median value of the serum hs-CRP level [1.20 (0.67–2.38) vs 0.74 (0.41–1.17) mg/l, P <0.05] and the mean QTc interval (422.71 ± 23.73 vs 396.27 ± 18.48 ms, P <0.0001) was significantly higher in the OP pesticide exposed subjects. Pesticide exposure was significantly associated with CVD risk (Chi-Square χ2 = 6.480, P = 0.011) and QTc interval prolongation (χ2 = 13.846, P <0.001). A higher risk of CVD (odds ratio = 3.030; 95% confidence interval = 1.276 – 7.197) was observed in the OP pesticide exposed subjects. This study suggested that OP pesticide exposure should be considered as one of the significant risk factors for CVDs.

    Several previous studies have investigated the effects of occupational stress on the onset of diabetes mellitus (DM), but there are few studies of occupational stress and DM using the Brief Job Stress Questionnaire (BJSQ), a standard stress check method in Japan. This study aimed to determine the relationship between occupational stress factors and the onset of DM using the BJSQ. We examined 6,620 male company workers aged 40 years and above in 2013, using the BJSQ. Overall, 2,604 subjects with impaired glucose tolerance who were free of mental disorders and DM were followed-up for 5 years and re-examined in 2017. A retrospective data analysis was conducted in 2019. We documented 241 new cases of DM in 2017 (diabetes group). Compared with the non-diabetes group, the subjects in the diabetes group had significantly decreased “skill utilization”. A binomial logistic regression analysis (generalized linear model) revealed that “skill utilization” was associated with the risk of DM development in 2017 (odds ratio, 1.632; 95% confidence interval, 1.061–2.510). Our results showed that low skill utilization might increase the risk of diabetes development in Japanese male workers.

    We gave mice a 540 mg/kg dose of LD50 acephate, followed by an assessment of acephate, methamidophos (MP), and choline esterase (ChE) activity for up to 4 hours (hr) in order to investigate the time course of acephate intoxication. At 1 hr, the blood acephate and MP levels were 428 ± 90 µg/ml (mean ± SEM) and 4.2 ± 0.4 µg/ ml, respectively. The liver acephate levels were similar to those in the blood, but the liver MP levels were approximately 3.5 times that of the blood at 1 hr. The brain MP level tended to be higher than the blood MP at 1 hr. These levels decreased gradually over 4 hr, but the brain acephate and MP levels surpassed the blood levels significantly at 4 hr, and after 2 hr, respectively. Serum, liver, cerebrum, cerebellum, and brainstem cholinesterase activity (ChE) were inhibited at 1 hr, and remained inhibited in all but the cerebellum until the end of the experiment. The obtained data were applied to previously reported autopsy cases of acephate intake. Experimental data suggest that brain MP is involved in acute acephate-induced poisoning, even after a reduction in blood acephate. In autopsy cases with suspected acephate poisoning, the MP level in the brain should be considered in addition to the ChE activity to diagnose the cause of death.

    In this study, we compare the results of a cross-sectional survey and secular changes between toner-handling workers and non-toner-handling workers, focusing on blood tests, urinalysis, respiratory function tests, and chest imaging results as indices of health effects. Of 116 employees who participated in the survey conducted at an office equipment manufacturer in Japan, 65 male employees who could be followed up for 10 years were included in the analysis. Thirty-eight workers engaged in toner-handling operations were considered toner-handling workers, and 27 not engaged in these operations were considered non-toner-handling workers. The blood tests (WBC, CRP, IgE, KL-6, and SP-D), urinalysis (8-OHdG), respiratory function tests (PEFR, VC, %VC, FEV1.0, and FEV1.0%), chest radiography, and chest CT results were compared between both groups. Non-toner-handling workers had significantly higher 8-OHdG/Cre at baseline and KL-6 at year 10 than did toner-handling workers. There were no significant differences between the results of the cross-sectional survey and a longitudinal survey of respiratory function test results. We conclude that there were no adverse health effects due to toner exposure.

    The ever-changing social implications of the COVID-19 pandemic have resulted in an urgent need to understand the working environments and health status of workers. We conducted a nationwide Internet-based health survey of Japanese workers in December 2020, in the midst the country’s “third wave” of COVID-19 infection. Of 33,087 surveys collected, 6,051 were determined to have invalid responses. The 27,036 surveys included in the study were balanced in terms of geographical area, sex of participants, and type of work, according to the sampling plan. Men were more likely than women to have telecommuted, while women were more likely to have resigned since April 2020. Forty percent and 9.1% of respondents had a K6 score of 5 or higher and 13 or higher, respectively, and they did not exhibit extremely poor health. The present study describes the protocol used to conduct an Internet-based health survey of workers and a summary of its results during a period when COVID-19 was spreading rapidly in Japan. In the future, we plan to use this survey to examine the impact of COVID-19 on workersʼ work styles and health.

    A 75-year-old-man experienced liver dysfunction and was diagnosed with decompensated liver cirrhosis. His serum hepatocyte growth factor (HGF) was very high (16.24 ng/ml). Because the etiology was unclear, we considered the possibility of amyloidosis. Biopsy of the mucosa of the stomach, duodenum and rectum demonstrated amyloid deposition. From the findings of Congo red staining and immunohistochemical analyses, we made a diagnosis of systemic amyloid light-chain amyloidosis. Unfortunately, the patient died one month after the diagnosis. We considered that serum HGF was useful for the diagnosis and prediction of prognosis of primary systemic amyloidosis.

    Endometrioid carcinoma is the most common histological type of concurrent synchronous cancers of the uterus and ovary. Here we report a case of synchronous seromucinous carcinoma of the ovary and mucinous carcinoma of the endometrium with a literature review. A 51-year-old multiparous female complained of irregular bleeding and shortness of breath. Computed tomography revealed a large pelvic mass that consisted of cystic and solid components, a tumor of the endometrium, and a large amount of pleural effusion. An endometrial biopsy indicated adenocarcinoma, and adenocarcinoma cells were found in the pleural fluid. The patient with advanced ovarian cancer or endometrial cancer with massive pleural effusion received three courses of neoadjuvant chemotherapy (NAC) with paclitaxel and carboplatin followed by interval debulking surgery (IDS). The NAC was effective, and IDS was performed with no gross residual lesions. The post-operative diagnosis was seromucinous carcinoma of the ovary in FIGO (2014) stage IVA (ypT3cNxM1a) and mucinous carcinoma of the endometrium in FIGO (2008) stage IA (ypT1aNXM0). Three courses of postoperative TC therapy were performed, and maintenance therapy with Bevacizumab is ongoing. The patient is well without evidence of recurrence, sixteen months after surgery.

    Decompression illness (DCI), a syndrome following inadequate reduction in environmental pressure, has two forms: decompression sickness and arterial gas embolism after pulmonary barotrauma. Recompression therapy using oxygen, a kind of hyperbaric oxygen therapy, has been considered the gold standard treatment for DCI, although there is no randomized controlled trial evidence for its use. We evaluated the effectiveness of recompression therapy in treating DCI by reviewing the reported therapeutic results of serious DCI, especially neurological disorders. Early or ultra-early recompression therapy did not dramatically improve clinical recovery from DCI symptoms, including spinal cord disorders. In contrast, early first aid normobaric oxygen inhalation highly improved or stabilized clinical conditions of DCI. Based on these clinical results, the international committee for hyperbaric and diving medicine has stated that cases of mild DCI may be managed without recompression therapy. Further work is needed to clarify the clinical utility of recompression therapy for spinal injury as a common symptom of DCI. We also point out that the Japanese decree “Ordinance on Safety and Health of Work under High Pressure”, which describes work under hyperbaric environments, has some serious issues and should be amended on the basis of scientific evidence.

    We present a case of a 59-year-old female who had been treated for optic neuritis 2 years before being transferred to our hospital. She had been positive for anti-AQP4 antibodies. No cerebrospinal lesions were observed, and based on the diagnosis of neuromyelitis optica spectrum disorder (NMOSD), 5 mg/day oral prednisolone was continued for 2 years. Acute lower back pain and urinary retention appeared on day X. On day X + 1, consciousness disturbance (JCS level II) and paraplegia appeared, and she was transferred to our hospital. Neck stiffness, paraplegia, and urinary retention were present. A cerebrospinal fluid examination revealed mononucleosis-dominant pleocytosis (1,232 cells/μl). Brain magnetic resonance imaging (MRI) showed multiple lesions around the ventricles and corpus callosum, and spinal MRI revealed a longitudinally extensive transverse myelitis lesion (C2–Th5). A relapse of NMOSD was diagnosed and steroid pulse therapy was started, but the symptoms progressed and quadriplegia and coma occurred. Head MRI showed new deep white matter lesions around the ventricles. Plasma exchange was added after the second steroid pulse. The patient’s consciousness gradually improved, and spontaneous movement of the left upper limb eventually appeared. We experienced a case of NMOSD that relapsed with multiple cerebrospinal lesions despite corticosteroid therapy, but plasmapheresis therapy was effective.

    Elderly people need a means to be able to move at their own will in order to stay socially active. One of the means of transportation is a mobility scooter. The purpose of this study was to find out how community-dwelling elderly people came to use a mobility scooter as a means of transportation and how they use it in their daily lives. We conducted a semi-structured interview with four participants regarding their background and actual experience of using a mobility scooter, and analyzed the data qualitatively and descriptively in three categories: Reason for Using a mobility scooter; Safe Use; and Activity and Participation. The reasons for using a mobility scooter were “Surrendered the driverʼs license”, “Loss of means of mobility due to lower limb disability”, “Interest in mobility scooters and Recommendation from others”, and “Family support”. “Safe use” consisted of four sub-categories: “Simple driving operation and safety assistance equipment”, “Handling in a dangerous situation”, “Current situation of daily use of mobility scooters without danger”, and “Intention to continue using mobility scooters”. In the “Activity and Participation” category, the three subcategories were “Maintain and expand activities”, “Interact with others”, and “Enjoy shopping by myself”. While the use of mobility scooters enhances a personʼs life, it was suggested that efforts to prevent accidents should be made.

    We report 3 cases of surgical resection for lung metastasis more than 15 years after initial surgery for breast cancer. Case 1: A 77-year-old woman was referred to our hospital because of a lung nodule in the left lower lobe detected in a computed tomography (CT) scan. She had undergone breast preservation therapy for breast cancer 15 years before the first visit. Left lower lobectomy was performed via video-assisted thoracoscopic surgery (VATS). The pathological diagnosis was lung metastasis of breast cancer, based on positive immunohistochemical staining of estrogen receptor (ER) and gross cystic disease fluid protein 15 (GCDFP-15). Case 2: An 88-year-old woman had undergone a mastectomy for breast cancer 23 years previously. A CT scan revealed a nodule in the upper lobe of the left lung. A wedge resection of the left upper lobe was performed. Because immunostainings for progesterone receptor (PgR) and GCDFP-15 were positive, the pathological diagnosis was metastasis of breast cancer. Case 3: A 78-year-old woman had undergone right mastectomy for the breast cancer 29 years previously. The patient was referred to our hospital because of a nodule in the right lung in a CT scan. Thoracoscopic right upper lobectomy was performed. The pathological diagnosis was lung metastasis of the breast cancer, with immunohistochemical positivity to ER, PgR, and focally to GCDFP-15. A differential diagnosis between primary lung cancer and metastasis of breast cancer on the basis of the findings of a CT scan is often difficult. It is important to obtain the previous clinical information about the breast cancer before VATS, even in patients with a long disease-free interval of more than 15 years.

    An 86-year-old female hospitalized for right femoral fracture complained of a sudden abdominal pain and vomited. Contrast-enhanced computed tomography (CECT) of the abdomen showed an ileal closed loop with dilatation of the oral side intestine. She was diagnosed with a bowel obstruction due to a paracecal hernia with incarceration and underwent an emergency operation. Under laparoscopy, the responsible ileum was incarcerated into the paracolic sulcus and strangulated. After releasing the strangulation by cutting the hernia hilum, the incarcerated ileum did not show any necrotic change. In this case, the CECT suggested paracecal hernia, showing the characteristic position between the cecum and the intestinal loop, which we successfully treated with a single incisional laparoscopic surgery.

    Medical staff in a hospital or nursing facility should take care of aged individuals with dignity and respect. We conducted a survey on aged individuals to derive under what care circumstances they had a sense of shame, using 12 illustrations, drawn by ourselves, which were common daily care scenes where nurses and patients meet. This survey was conducted at 4 care facilities in A prefecture, Japan. The number of surveyed persons was 43, with the following exclusion criteria: over 60 years old, more than third level of care needed, and non suspected of having dementia. We got the following results from the answers of 41 persons: 1. When elder persons are surrounded by people other than the care staff, they feel more of a sense of shame than when alone; 2. They feel more sense of shame when they use a wheelchair than when they use crutches; 3. They do not feel much shame when they get a bed-bath, even if other persons are there; and 4. Male patients feel more shame than females when they meet their family. These results suggest that elderly patients feel a stronger sense of shame when they are seen by others than when they are seen by care staff. The result 2 suggests that the use of a wheelchair exposes their physical weakness to others. Males feel a stronger sense of shame when they show a weakness in their gender role. We conclude that the sense of shame of aged individuals in daily life scenes in a care facility depends on their gender and whether or not they are surrounded by other persons.
