Acetabular erosion, intrusion of the prosthesis into the pelvis, is the most serious late complication of hemiarthroplasty. For the detailed observation on this lesion, the authors reviewed 55 patients who underwent femoral head replacement and were followed up to at least 1 year after operation. The acetabular erosion were present in 18 patients(32.7%) out of the total 55 patients. Based on the results of this study, the authors presented a new classification of acetabular eorsion: Stage I(erosion of the cartilage only) was seen in 11 patients, stage II (evidence of the initial bony erosion) in 4 patients,and stage III(intraosseous intrusion of the metallic head) in 3 patients. Revision arthroplasty was obligatory in two of the three stage III patients. The severity of symptoms did not always correspond with the radiological changes. The acetabular erosion was more common in younger patients, in male patients and in patients with avascular necrosis of femoral head than in older patients, in female patients, and in patients with femoral neck fracture. The tendency of acetabular erosion occurring mainly in younger and male patients is probably attributed to their better survival and greater activity.

Since the residency training program in internal medicine changed from a four-year to a three-year program in 2017 in Korea, issues of an optimal training program for the gastrointestinal (GI) fellowship has arisen. Currently, the evaluation criteria for a GI fellowship in Korea include the following; 1) the total number of assigned patients during the training period, 2) the number of GI endoscopy procedures, 3) attendance at academic conferences, and 4) research presentations. However, competency-based training should be introduced in the GI fellowship training program. The current issues of GI fellowship training in Korea include the following; 1) reorganization of the GI fellowship education system and consideration of an optimal training period following the introduction of the three-year internal medicine residency training program, 2) development of a standardized, competency-based GI fellowship training program, 3) provision of a support program for instructors in GI fellowship education, 4) introduction of a mentor-mentee system, 5) introduction of an accreditation system for GI fellowship, 6) supplementation of a GI sub-specialty qualification system, and 7) provision of benefits to GI sub-specialists.

Sedation is an essential component for gastrointestinal endoscopy. It allows patients to tolerate unpleasant endoscopic procedures by relieving anxiety, discomfort, or pain. It also reduces patient's risk of physical injury during endoscopic procedures, while providing the endoscopist with an adequate setting for a detailed examination. For the safety during endoscopic sedation, patient monitoring is crucial. Minimal monitoring requirements during endoscopic sedation are periodic assessment of blood pressure and application of continuous pulse oximetry. Continuous electrocardiography is recommended in selected patients with high risk for sedation or have cardiopulmonary diseases. Continuous supplemental oxygen is also recommended for endoscopic sedation. This study describes detailed monitoring and associated devices based on the current guidelines and recommendations from gastrointestinal society of America, Europe, and Korea.
