BACKGROUND AND AIM: The association between physical activity (PA) and sarcopenia has mostly been investigated in older people, with few studies focused on earlier life stages. The present study aimed to determine whether higher PA levels are associated with a lower sarcopenia risk in middle-aged and early older people. METHODS: This was an 8-year follow-up study. Participants were 6,500 community-dwelling adults aged 40-74 years who participated in the baseline questionnaire survey conducted in 2011-2014 in Japan. Levels of total and leisure-time PAs at baseline were assessed using validated metabolic equivalent scores. Multi-frequency bioelectrical impedance analysis and handgrip strength measurement were performed in 2021-2022, and participants with low height-adjusted appendicular lean mass (<20th percentile) and low grip strength were diagnosed as having sarcopenia (outcome). Covariates were demographics, body size, lifestyle, and disease history at baseline. RESULTS: The prevalence of sarcopenia was 137/2926 (4.7%) for men and 127/3574 (3.6%) for women. Higher total PA levels were associated with lower odds of sarcopenia (P for trend = 0.0278), with the second highest group having a significantly lower OR (0.51) than the lowest group (reference) in women, but not in men. Regarding leisure-time PA, those engaged in leisure-time vigorous PA had a lower OR of sarcopenia than those who did not (OR = 0.67, P = 0.0625). CONCLUSION Higher levels of total PA are associated with a lower risk of sarcopenia in women but not in men, suggesting a sex difference in this association. In addition, high levels of vigorous leisure-time PA may be effective for preventing sarcopenia.

Objective: In this study, we investigated the occurrence of skin damage following the initiation of low-dose lamotrigine.Methods: We retrospectively analyzed the incidence of skin disorders within 8 weeks of the start of lamotrigine administration, prescribing for 3 years from July 2014 to June 2016.In addition, we also confirmed the onset time of skin disorders in the low- and normal-dose groups.Results: The incidence of skin damage was 7.7 and 24.6 % in the low- and normal-dose lamotrigine start groups, respectively. The onset of skin disorders was relatively early in the normal-dose lamotrigine start group.On the other hand, no tendency was found in the low-dose lamotrigine start group because the number of cases was small.Conclusion: The initiation of low-dose lamotrigine and extension of introduction period might reduce the onset of early skin damage.

Introduction: Intravascular large B-cell lymphoma (IVLBCL) is a rare disease entity of non-Hodgkin lymphoma. Patients with IVLBCL frequently have neurological symptoms associated with cerebrovascular infarction or central nervous system involvement of malignant lymphoma. Case: A 67-year-old man consulted the Department of Hematology at our hospital because of fever of unknown origin, anemia and increased serum lactate dehydrogenase. Although IVLBCL was strongly suspected, no lymphoma cells were found by multiple bone marrow aspirations and skin biopsies. Two months later, he developed hyperactive delirium, which was difficult to manage using antipsychotic agents. Brain MRI revealed multiple hyper-intense infarct-like lesions on diffusion-weighted images. After assessment of bone marrow aspiration and skin biopsies, he was administered an enough dose of prednisolone to manage malignant lymphoma. Hyperactive delirium rapidly improved. Discussion: In patients with IVLBCL, corticosteroids may be useful to manage hyperactive delirium due to cerebrovascular infarction or central nervous system involvement of IVLBCL.

BACKGROUND: Age-related musculoskeletal diseases are becoming increasingly burdensome in terms of both individual quality of life and medical cost. We intended to establish a large population-based cohort study to determine environmental, lifestyle, and genetic risk factors of musculoskeletal and other age-related diseases, and to clarify the association between vitamin D status and such diseases. METHODS: We targeted 34,802 residents aged 40-74 years living in areas of northern Niigata Prefecture, including Sekikawa Village, Awashimaura Village, and Murakami City (Murakami region). The baseline questionnaire survey, conducted between 2011 and 2013, queried respondents on their lifestyle and environmental factors (predictors), and self-reported outcomes. Plasma 25-hydroxyvitamin D (25[OH]D) concentration, an indicator of vitamin D status, was determined with the Liaison® 25OH Vitamin D Total Assay. The primary outcome of this study was osteoporotic fracture; other outcomes included age-related diseases including knee osteoarthritis, perception of chronic pain, dementia, and long-term care insurance use. Mean ages of men and women were 59.2 (SD = 9.3, N = 6907) and 59.0 (SD = 9.3, N = 7457) years, respectively. From the blood samples provided by 3710 men and 4787 women, mean 25(OH)D concentrations were 56.5 (SD = 18.4) nmol/L (22.6 ng/mL) and 45.4 (SD = 16.5) nmol/L (18.2 ng/mL), respectively. DISCUSSION Follow-up surveys are planned every 5 years for 15 years, and incident cases of our targeted diseases will be followed at hospitals and clinics in and nearby the cohort area. We anticipate that we will be able to clarify the association between vitamin D status and multiple disease outcomes in a Japanese population.

We investigated the effects on medical education of early exposure of undergraduate students to a summer camp for children with asthma. An objective evaluation by the editorial staff found final improvements in the following areas (in descending order of frequency): learning of basic medical behavior (91% of students); cooperative attitude of medical staff in general treatment with the patient and the patient's family (88%); understanding of childhood growth and development (80%); knowledge of childhood asthma (69%); and mastery of basic techniques for therapy and examination (41%). The differences in the ratio of improvement (%) before and after visiting the camp, were (in descending order of frequency): cooperative attitude of medical care staff in general medical treatment with the patient and the patient's family (47%); understanding of childhood growth and development (45%); knowledge of childhood asthma (38%); learning of basic medical manner (34%); and mastery of basic techniques for therapy and examination (25%). These findings suggest that a summer camp is useful for exposing undergraduate medical students to children with asthma and is effective for helping them understand patients and family-oriented pediatric medicine.

A 60-year-old male patient visited the Oriental Medicine Research Institute of the Kitasato on ***** because of abdominal discomfort. Hangeshashin-to was administered to him and the abdominal discomfort was relieved. He continued to take Hangeshashin-to from June to August 1997. He had chills, high fever, and fatigue from ********. He stopped Hangeshashin-to and took Shosaiko-to for five days because of liver dysfunction. He was admitted to our hospital on ********. Antibiotics and stronger neo-minophagen C were administered to him. A chest roentgenogram revealed a ground-glass shadow on the left upper lung, and Shosaiko-to was discontinued. The patient began to complain of dyspnea and had fine crackles on the chest. A chest roentgenogram and chest CT showed interstitial pneumonitis. Oral predonisolone therapy was started for hypoxemia and the patient improved. A drug lymphocytes stimulation test revealed that lymphocytes were stimulated by Shosaiko-to and its components, Saiko and Ogon. A chest roentgenogram just before ingesting Hangeshashin-to revealed the interstitial change of the lung. Taken all together, this patient suffered from druginduced hepatitis and pneumonitis as a result of ingesting Hangeshashin-to and Shosaiko-to.

We made researches into various factors underling the loneliness of the elderly, based on interviews conducted in july 1995 with old people living alone in Hiroshima City. Loneliness was assessed by LSO, and as related factors, such items as period of living alone, self-assessment on solitude, lifestyle, self-rated health status, competence for daily work, social support network, morale, self-esteem, depression, and subjective symptoms of stress were examined.
We made multiregression analysis using loneliness as a dependent variable and other factors as independent varibles. The results were as followed.
The loneliness of old people living alone was significantly correlated with self-esteem and instrumental support.

Seven wrestlers, whose body weights should be reduced about ten per cent in relatively short period of time to be acknowledged for intercollegeate competition, were selected, and their daily food intakes in reduction through recovery period of body weight were estimated. Simultaneously, some blood and urine components were analysed, performance capacities (grip and back strength power) were measured, and gross balances of nitrogen and potassium were calculated as the difference between their intakes and urinary outputs, to discuss the influence of rapid weight reduction.
For several days of the last stage of reduction period, the average intakes per kg body weight per day were about 20 kcal for energy, about 1.7 g for protein, about 20 g for food moisture and drinking water, total intakes per day were about 2 g for sodium and about 1 g for potassium respectively.
During about seven days of recovery period, these intakes were increased to higher level, which were as average about 60 kcal for energy, about 2 g for protein, 46-73 g for food moisture and drinking water per kg body weight, about 5 g for sodium and about 3 g for potassium per day, respectively.
During reduction period, the negative balances of nitrogen and potassium, slight reduction of performance capacities and dehydration symptoms in blood components (Ht value, and contents of Hb, plasma protein plasma urea nitrogen) were observed.
During recovery period, the body weights were recovered rapidly to normal level, nitrogen and potassium were turned to positive balance, but some components (Ht value, plasma protein) were not completely recovered to their normal level.
As far as the average food composition in recovery period was concerned, not so remarkable deficiency was observed, but the personal deviations in their intakes were distinct. From these results, it is suggested that by better balanced combination of food intake, personal body conditions of these young sportsmen with high physical strength would recover to their normal level more quickly and more completely.
