A questionnaire was conducted on the living and working conditions of inhabitants in the suburbs of a city in Hiroshima Prefecture. Respondents received medical and nutritional examinations. A summary of our findings is as follows:
Those persons who are apparently overworking themselves eke out their energy deficiency by taking diets rich in carbohydrate complex. Their major health problems are hypertension, ischemic changes in ECG, anemia and lower cholinesterase activity.
There were indications that agricultural chemicals have harmful effects on the health of the examinees.
In contrast, many of those who work less consume large-even excessive-amounts of animal proteins and fats. Among them prevail liver failxure and metabolic disorders.
In either group of the people examined, there was amundant evidence to show that they are at risk of developing arteriosclerosis.
These findings should be taken into consideration when a health control program is implemnted.

An investigation was made into the health conditions of oyster farmers in Hiroshima Bay with reference to their job requirements and way of life. The findings are as follows:
Their working conditions are harsh. However, compared with those engaged in agriculture, the oyster farmers eat fairly large amounts of calorific foods, especially animal products. Their alcoholic consumption is also large. They get enough sleep and rest on a regular basis.
Mild obesity, hypertension and hyperlipidemia are prevalent among men, and tendency of obesity is more common among women. Furthermore, those with the risk factors for arteriosclerosis account for more than 50% of the people examined.
From these findings, it could be said that their health is at risk. Appropriate and effective measures should be taken promptly so as to reduce the risks, particularly those risks associated with arteriosclerotic damage. Mechanization will be one of the measures against the health resks that oyster famers are now exposed to. Without preventive measures, there might be an outbreak of the diseases originating in the blood vessels.

Osmotic demyelination syndrome is a pathological condition that leads to electrolyte imbalances and rapid correction, resulting in pseudobulbar palsy, quadriplegia, and altered consciousness. Approximately 33-55％ of affected patients experience residual functional impairment. Herein, we describe a case of a patient with osmotic demyelination syndrome who developed locked-in syndrome during the disease course, underwent rehabilitation treatment, and achieved complete remission without sequelae.The patient was a 47-year-old man who was admitted to hospital A owing to weakness in the lower extremities and dysarthria. He had severe hyponatremia and received sodium correction. However, on hospital day 9, dysarthria redeveloped and involuntary finger movements were noted. Osmotic demyelination syndrome was suspected based on the findings of magnetic resonance imaging of the head and clinical course, leading to his transfer to hospital B. Steroid pulse and rehabilitation therapies were initiated at hospital B. By the 19th day of symptom onset, his limb and facial muscle paralysis progressed, leading to locked-in syndrome. Thereafter, the patient was transferred to hospital C, where he received physiotherapy, occupational therapy, and eating training, markedly improving his physical functions. He was discharged from hospital C, 4 months after the symptom onset, with limited range of motion of the fingers and weakness of the extremities and continued to receive outpatient rehabilitation treatment. His symptoms improved further, and 1 year after the onset of symptoms, he returned to work without any sequelae.
