In this study, we investigated the effects of a 2-year swimming program on suppressing bone loss in postmenopausal women. There were 22 subjects who participated in the swimming program (mean age 59.5 yr) and 19 controls (mean age 59.3 yr) . The program consisted of one-hour exercise sessions ; and the swimmers had on average 1.5 sessions per week. BMD at the lumbar spine (L2-L4) and proximal femur (neck, trochanter, and Ward's triangle) were measured by dual X-ray absorptiometry (DXA) ; and leg extensor power was measured using a dynamic leg extensor power rig. All the measurements were taken at baseline, 1 and 2 years. Height, weight, calcium intake and daily activity profiles were similar between the two groups, and these changed little throughout the experiment. In regard to leg extensor power, the swimming group had a significant increase at 1 and 2 years. At 2 year, the swimming group demonstrated 4.4%, 5.7% and 3.4% increases in BMD at the femoral neck, trochanter and Ward's triangle, respectively, while the control group showed slight decreases of BMD at the femoral neck (-0.2%) and Ward's triangle (-1.4%) . Significant differences in the rate of change in BMD at each site were observed between the two groups. The swimming group showed a decrease in lumbar spine BMD, as did the control group and the rate of the decline did not differ between the two groups. This study suggests that a 2-year swimming program for postmenopausal women can induce the beneficial effects of retarding bone loss at the proximal femur site and increasing leg extensor power.

In order to avoid the risk of COVID-19 among our clinic staffs, remote medical care using tablet-type devices was conducted in our fever outpatient clinic. In about 5 months, there were 87 patients with COVID-19 diagnosed by PCR test. Among them, 24 patients (15 men and 9 women, average age 36.2 years) were treated with Kampo medicine. Four of 24 patients required hospitalization. All patients, including those hospitalized cases, improved their symptoms during the observation period. We believe that Kampo medicine is effective in the early treatment of COVID-19. In addition, we consider that remote medical care using tablet-type devices is one of the useful methods in the treatment of highly contagious infectious diseases.

The patient was a 73-year-old woman. She had been treated for squamous cell carcinoma of the lung (cT3N3M0, Stage IIIC) at our department. The patient had low back pain due to retroperitoneal lymph node metastasis; in June 2022, this was exacerbated as lung cancer progressed. She had difficulty in body movements due to edema in both lower limbs, in addition to the pain. Consequently, she was urgently admitted on July 8 and received radiotherapy (30 Gy/10 fractions) for retroperitoneal lymph node metastasis. She was being given tapentadol at a dose of 200 mg/day for relief of her pain. However, she was switched to fentanyl patch at a dose of 1200 µg/day during her hospitalization, which resulted in relief of low back pain. The underlying disease causing the edema was investigated. Based on physical and laboratory findings and medical history, lymphedema associated with retroperitoneal lymph node metastases was diagnosed. On day 31 of hospitalization, the patient was allowed to be temporarily discharged from the hospital because the edema had improved and the activity of daily living around the bed had increased. Treatment methods for lymphedema associated with lymph node metastasis have not been established, but the efficacy of radiotherapy has been reported. We have herein reported a case of lymphedema that was improved by radiotherapy after it was differentiated from other diagnoses.
