PURPOSE: This study aimed to create a digitized database of fabricated obturators to be kept for patients' potential emergency needs. MATERIALS AND METHODS: A chairside intraoral scanner was used to scan the surfaces of an acrylic resin obturator. The scanned data was recorded and saved as a single standard tessellation language file using a three-dimensional modeling software. A simulated obturator model was manufactured using fused deposition modeling technique in a three-dimensional printer. RESULTS: The entire obturator was successfully scanned regardless of its structural complexity, modeled as three-dimensional data, and stored in the digital system of our clinic at a relatively small size (19.6 MB). A simulated obturator model was then accurately manufactured from these data. CONCLUSION: This study provides a proof-of-concept for the use of digital technology to create a digitized database of obturators for edentulous maxillectomy patients.

This study clarified practices in end-of-life care for non-malignant chronic illness patients by expert nurses in general hospitals. Interviews with 7 chronic illness specialist nurses on practice cases were conducted, and final labels were elicited using a qualitative synthesis method（KJ method）. As patients’ conditions deteriorated, nurses defined the necessary interactions to support patients’ decision-making for living their own way of life and accompany patients and families based on their experience, and using patients’ restoration of self-esteem, sense of satisfaction, and acceptance as indices. In general hospitals, measures to cope with pain for patients not receiving life-prolonging treatment were insufficient;and while it was difficult to agree on care between medical professionals and to maintain care in other facilities, expert nurses grasped patients’ wishes on a daily basis and made arrangements for them to permeate through family and community care systems. In end-of-life care in treatment settings, it is necessary to be supportive so that the family and medical professionals can continue the patient’s care. Medical professionals who have been involved from the initial diagnosis stage need to improve their awareness and support skills as medical professionals to be involved purposefully from an early stage to the final stage.

Chronic expanding haematoma (CEH) is a rare type of haematoma that enlarges slowly and continuously without coagulation. It can occur following surgery because of shear stress-induced bleeding in the scar tissue between the subcutaneous fat and fascia. We present three cases of large chronic CEH that were successfully treated with triamcinolone injections. Three female patients developed large chronic CEH at 9 months, 5 years, and 6 years, respectively, after latissimus dorsi flap harvesting for breast reconstruction. Although the condition did not improve after multiple sessions of haematoma aspiration in the first two patients, it resolved following a single 40-mg triamcinolone injection along with appropriate compression dressing for several weeks. In the third patient, triamcinolone was injected immediately after the initial aspiration of the haematoma, and the condition improved considerably. There were no side effects in any of the patients. To the best of our knowledge, this is the first report of successful treatment of large CEH using triamcinolone. Therefore, we suggest that triamcinolone injections be considered for the treatment of CEH.
