RESUMEN
Introduction：Intracranial hemorrhage after severe coronavirus disease 2019 (COVID-19) is associated with increased mortality and unfavorable patient outcomes.Case：A man in his 60s with independent activities of daily living (ADL) was diagnosed with COVID-19, and placed on a ventilator on Day (D)-3 and VV-ECMO on D-5. On D-23, an emergency craniotomy was performed for a left acute subdural hematoma. The patient was weaned from VV-ECMO on D-27. On D-33, sitting was initiated. On D-36, the patient was weaned from the ventilator and began exercise therapy. The Glasgow coma score (GCS) was E2V1TM4. Basic movement as assessed by the Functional Status Score for ICU (FSS-ICU) and Barthel Index (BI), was 3 and 0 points, respectively. On D-40, wheelchair use commenced. He began standing with a long leg orthosis on D-50, and began walking on D-53.On D-67, the patient transferred to a convalescent hospital. His GCS was E4V4M6. Generalized cognitive decline and motor paralysis were noted. The right upper limb, hand, and lower limb were assessed as Brunnstrom recovery stage IV, V, and V, respectively. The patient's grip strength was 11.9 kg [right] and 18.3 kg [left]. His knee extensor strength was 0.13 kgf/kg [right] and 0.19 kgf/kg [left]. The FSS-ICU, walking speed, and BI were 21 points, 0.17 m/sec, and 40 points, respectively. The patient was discharged on D-240.Discussion：The Early Mobilization and Rehabilitation Expert Consensus reports that early mobilization and active exercise can improve ADL at discharge. Our patient was weaned from VV-ECMO as soon as possible and practiced standing and walking with a long leg orthosis, resulting in a better outcome.
RESUMEN
Herein is reported our experience of radiation therapy using a real-time tumor-tracking and gated radiotherapy (RTRT) system for inoperable pancreatic cancer. Three unresectable pancreatic cancer patients were treated with intraoperative electron beam radiation therapy, at the time of open biopsy, and postoperative external beam radiation therapy using an RTRT system with a 2.0 mm diameter gold ball implanted into the pancreas. The total BED's (alpha/beta=10) was intended to be equivalent to that of delivering 60 Gy by 2.0 Gy/fraction, while the actual dose schedules were individualized. The movement of the pancreas was analyzed based on the 3-dimensional marker positions during the RTRT. The side effects and tumor responses were evaluated. During the RTRT course, the average movement of markers in the x (left to right), y (cranial to caudal) and z (dorsal to ventral) directions were 3.0 mm (1.7- 5.2 mm), 5.2 mm (3.5 - 6.8 mm) and 3.5 mm (2.7 - 5.1 mm), respectively. During and after the course of postoperative radiation therapy, no acute side effects of RTOG grade II or higher were detected. The objective tumor responses, as evaluated by CT scans 3 months after the treatment, were 2 partial responses and no response in one patient. Using the RTRT technique the margin of treatment planning and the possible errors in target localization were reduced, and the 3-dimensional movement of the internal marker implanted in the pancreas was able to be analyzed.
