Distigmine bromide is an anticholinesterase used to treat urinary retention. We describe a case of decreased serum cholinesterase caused by a usual oral dose of distigmine bromide for urinary retention. An 84-year-old man, who had been received chemotherapy for carcinoma of the lower gingiva, suddenly decreased serum cholinesterase to 21 IU/L in 7 days of administration of distigmine bromide 5mg without clinical symptoms. Serum cholinesterase improved after stopping the administration of distigmine bromide. This case shows that oral surgeons should be aware of the possibility of decreased serum cholinesterase in patients taking distigmine bromide.

We report a case of pyostomatitis vegetans associated with ulcerative colitis. The patient was a 25-year-old woman referred to our hospital because of irritative pain of the right side of the buccal mucosa. She had been receiving mesalazine for ulcerative colitis for 4 years. An erosion with a cobblestone appearance and a small ulcer were observed on the right side of the buccal mucosa. Histopathological examination showed subepithelial microabscesses containing lymphocytes and eosinophils in the subepithelial connective tissue. We finally diagnosed pyostomatitis vegetans associated with ulcerative colitis. The oral lesion completely disappeared 1 month after the administration of prednisolone.

We report two cases of genioplasty performed using a navigation system. In recent years, virtual orthognathic surgeries have been performed using simulation software with data from preoperative computed tomography (CT), and the osteotomy design, direction and distance of bony segment movement have been established. Despite the accuracy of simulations using three-dimensional CT data, results obtained from simulations cannot be effectively applied to clinical practice unless comparisons can be made to actual surgery. We report our experience of performing genioplasty using simulation software with preoperative CT data, and established the osteotomy design as well as the direction and distance of bony segment movement. Simulation-guided navigation osteotomy was performed with reference to simulation results transferred to the navigation system. A reference antenna was attached to the head of the patient using a headband. Next, interfacing laser registration was performed. Osteotomy was then performed along the osteotomy line drawn on the chin bone surface using piezosurgery and a tracker, and the bone segment was mobilized by down-fracture using a bone saw. Using the image of the simulated repositioned bone segment shown on the navigation system screen, the bone segment was moved to the determined position and fixed. Our results suggest that use of a navigation system allows safer, more precise genioplasty.
