JOURNAL FREE ACCESSThe aim of this study was to examine the relationship between shift-work disorder (SWD) and environmental and somatic factors related to falling asleep among rapidly rotating shift workers in a manufacturing industry.A total of 556 male workers were recruited to complete a self-administered questionnaire regarding age, shift work experience, lifestyle, and family structure; the Epworth sleepiness scale (ESS); the Pittsburgh sleep quality index (PSQI); and the Horne and Ostberg questionnaire, a questionnaire for environmental and somatic factors related to falling asleep. We classified workers according to having SWD or not, and compared workers with SWD with those without this disorder in terms of all items covered in the aforementioned questionnaires. A total of 208 workers (62.8%) working rapidly rotating shifts were diagnosed with SWD. The ESS and PSQI scores and scores for environmental and somatic factors were significantly higher in workers with SWD than in those without this disorder. The ESS scores and scores for environmental and somatic factors were also associated with SWD in the logistic regression analyses. We suggest that susceptibility to SWD in the manufacturing industry may be associated with environmental and somatic factors related to falling asleep.View full abstractDownload PDF (452K)

JOURNAL FREE ACCESSA 14-year-old girl with cerebral palsy (spastic diplegia) underwent examination due to a chief complaint of right foot pain, and was diagnosed with a stress fracture of the central one third of the navicular bone. The fracture was considered to have developed due to repeated loading on the navicular bone as a result of an equinus gait.Therefore, she underwent osteosynthesis and Achilles tendon lengthening to correct the equinus deformity. Following our review of the current literature, we did not identify any reports of stress fracture of the navicular bone in cerebral palsy. We believe that in cases where cerebral palsy patients with paralytic equinus complain of foot pain, the possibility of stress fracture of the navicular bone should be considered.View full abstractDownload PDF (656K) -

JOURNAL FREE ACCESSA 31-year-old nulligravid woman with a 3 year history of infertility visited our hospital. After consultation and a transvaginal ultrasound and MR imaging, her uterine anomaly was identified as complete septate uterus: class V (a) by the American Fertility Society (AFS). She had a doubled uterine cervix and a vaginal septum. Hysteroscopic metroplasty was performed with the aid of a laparoscopy. Both tubal patencies were confirmed with indigocarmine in a laparoscopic image. Laparoscopic electronic cautery was also done on the left ovarian endometrioma (stage 1 endometriosis; the revised American Society for Reproductive Medicine (rASRM) classification 4 point minimal). We distrained an intrauterine device in the uterine cavity and removed it after two cycles of menstruation. The patient subsequently became pregnant during her third menstrual cycle and the current progress of her pregnancy is favorable.View full abstractDownload PDF (3257K)

JOURNAL FREE ACCESSThe aim of this study was to explore factors that ameliorate work ability by focusing on workersʼ capacity to deal with stress.The subjects were 1,330 workers from the Japanese information technology (IT) sector. Each subject completed questionnaires in 2011 and 2012 that consisted of the work ability index (WAI), the threeitem sense of coherence (SOC), and the Mental Health Improvement and Reinforcement Research of Recognition (MIRROR). The results of the WAI were also obtained in 2013. The median SOC score in 2011 was used to divide the subjects into two groups, the Low SOC group and the High SOC group, then we verified the factors that contributed to improved work ability in both of these groups over a two-year period. Results indicate that an improvement in work ability in the Low SOC group could be predicted by giving workers opportunities for education or training, by making efforts to reduce the stress of commuting, by clarifying their assignments, and by establishing support systems when troubles occur. For the High SOC group, such improvements could be predicted by giving workers job control, by giving education or training for the promotion of their abilities, and by establishing a system for assuming responsibility. In conclusion, improvements in the work environment can increase the work ability of Japanese IT workers in conformity with their capacity to deal with stress.View full abstractDownload PDF (735K)

JOURNAL FREE ACCESSThe norepinephrine transporter is selectively expressed in noradrenergic nerve terminals, where it can exert spatial and temporal control over the action of norepinephrine. The norepinephrine transporter mediates the termination of neurotransmission via the reuptake of norepinephrine released into the extracellular milieu. In the present brief review, we report our recent studies about the effects of various pharmacological agents such as fasudil, nicotine, pentazocine, ketamine and genistein on norepinephrine transporter function.View full abstractDownload PDF (719K)

JOURNAL FREE ACCESSWe report a 55 year old Japanese man with a history of alcohol abuse, who was in a near fasting state for the previous few days.He was admitted to our hospital with abrupt disturbance of consciousness. He presented disturbance of consciousness with extreme hypoglycemia and ketoacidosis with high β-hydroxybutyric acid concentration. Taking into account his living history, we diagnosed with alcoholic ketoacidosis (AKA). Symptoms ameliorated with glucose injection and fluid loading. AKA patients show abdominal pain, nausea or vomiting, but they are usually alert and lucid despite the severe acidosis. This case, however, presented comatose status caused by hypoglycemia. Poor oral intake of this patient was assumed to be the cause of hypoglycemia. Alcoholism may cause hypoglycemia accompanying with AKA, due to a low carbohydrate intake, the inhibition of gluconeogenesis, and reduced hepaticglycogen storage as seen in this case. Here, we report a case of AKA that demonstrated hypoglycemia with the literature review.View full abstractDownload PDF (708K) -

JOURNAL FREE ACCESSA 42-year-old woman visited our hospital with palpitations, excessive sweating, and finger tremors in March 2011. She was diagnosed with Gravesʼ disease based on the following test results: thyroid stimulating hormone < 0.01 μU/ml, free thyroxine 6.15 ng/ml, and thyrotropin receptor antibody 7.8 U/ml. Treatment with methimazole 30 mg and propranolol 30 mg was started, and her thyroid function showed improvement. However, significant manic symptoms, irritability, hallucinations, and delusions were noted, and she was hospitalized for her own protection in May 2011. Although treatment with aripiprazole 24 mg and lithium 400 mg was started, the hallucinatory and delusional symptoms persisted, necessitating adjustment of the antipsychotics. Her psychiatric symptoms showed amelioration in July 2011 after improvement in her thyroid function, and she was discharged from our hospital. After discharge, her thyroid function remained normal with methimazole 10 mg, and administration of the antipsychotics was discontinued. Affective psychotic symptoms such as altered mood and activity are frequently observed in cases with Gravesʼ disease, but there have been few reports describing cases with full-blown psychiatric disorders manifesting with features such as hallucinations and delusions as the chief symptoms requiring hospitalized treatment, as in the present case. In symptomatic psychosis associated with Graves’ disease, prolonged psychiatric symptoms might develop, and close cooperation with psychiatrists is thus important.View full abstractDownload PDF (734K) -

JOURNAL FREE ACCESSA 56 year old female was admitted to a local hospital after developing symptoms, including generalized fatigue, nausea and vomiting, from trauma. She was relocated to our hospital because she developed other symptoms, including disturbance of consciousness from hypercalcemia and a rash over her entire body. Her clinical symptoms (disturbance of consciousness, loss of appetite, nausea, vomiting, decrease in blood pressure, fever) and examination findings (low blood cortisol levels (1.2 μg/dl ), hypercalcemia (11.0 mg/dl ), peripheral blood eosinophilia (1,600 /μl )) lead to a diagnosis of adrenal insufficiency. In addition, a skin biopsy indicated eosinophilic infiltration, although her condition improved in the end with an oral dose of 30 mg/day of prednisolone. Hypercalcemia and peripheral blood eosinophilia are commonly known examination findings for adrenocortical insufficiency, but it is rare for either of these to be present as clinical symptoms.View full abstractDownload PDF (4118K)
