Résumé
We report a case of post coronavirus disease 2019 (COVID-19) condition, in which the patient suffered from a severe sense of fatigue and brain fog that was successfully treated with Kampo therapy. The patient was a 21-year-old man. He had been diagnosed with COVID-19 and hospitalized for follow-up examinations. He recovered without any complications and was discharged from the hospital, but continued to suffer from a severe sense of fatigue, coldness, dizziness, and a loss of concentration. Because of these symptoms, he had to spend most of the day lying down. One month later, he was hospitalized to receive Kampo therapy. We administered bukuryoshigyakuto for 2 weeks referring to his severe coldness and fatigue and then changed to renjuin for his fluid disturbance and blood deficiency. After starting Kampo therapy, his fatigue and dizziness gradually improved. He was discharged after 3 weeks of hospitalization and received Kampo therapy as an outpatient. One month later, he reported a dull feeling in his stomach and depression. We switched to kamikihitogohangekobokuto and added hachimigan. His activities of daily living improved and he could take 4.5-kilometer walk. He could return to work 4 months later. Kampo therapy may be useful for post COVID-19 condition that causes a sense of fatigue and brain fog.
Résumé
<b>Objective</b> Enveloping airflow, as opposed to direct airflow, warms the room by gently circulating the airflow along the floor, wall, and ceiling, thereby uniformly warming the entire room. The objective of our study was to determine the effects of air-conditioned heating by enveloping-airflow on sense of fatigue and comfort in healthy volunteers.<br> <b>Design</b> Eight healthy women, who often felt discomfort in an air-conditioned heating environment, participated in a randomized placebo-controlled crossover trial. Subjects rested for 30 minutes in a room air-conditioned either by enveloping airflow or by direct airflow, and then performed fatigue-inducing tasks for 2 hours.<br> <b>Methods</b> We evaluated the sense of fatigue by visual analogue scale (VAS), peripheral blood flow by laser-Doppler flowmetry, and sympathetic nerve activity by urinary vanillylmandelic acid level.<br> <b>Result</b> Air conditioning by enveloping-airflow, as compared to direct airflow, enhanced peripheral blood flow and attenuated sympathetic nerve hyperactivity caused by performing fatigue-inducing tasks. Moreover, it helped to maintain subjective levels of motivation and comfort, as well as to alleviate sense of fatigue and cold.<br> <b>Conclusion</b> Air-conditioned heating by enveloping-airflow is effective for attenuating sense of fatigue and discomfort as well as health maintenance.<br>
