6.Applications of Machine Learning in Bone and Mineral Research
Endocrinology and Metabolism 2021;36(5):928-937
In this unprecedented era of the overwhelming volume of medical data, machine learning can be a promising tool that may shed light on an individualized approach and a better understanding of the disease in the field of osteoporosis research, similar to that in other research fields. This review aimed to provide an overview of the latest studies using machine learning to address issues, mainly focusing on osteoporosis and fractures. Machine learning models for diagnosing and classifying osteoporosis and detecting fractures from images have shown promising performance. Fracture risk prediction is another promising field of research, and studies are being conducted using various data sources. However, these approaches may be biased due to the nature of the techniques or the quality of the data. Therefore, more studies based on the proposed guidelines are needed to improve the technical feasibility and generalizability of artificial intelligence algorithms.

PURPOSE: In 2004, a joint effort was undertaken between Dong-a University Hospital, Busan, Korea and Singapore General Hospital, Singapore, to promote laparoscopic radical prostatectomy (LRP) to yet another level by enhancing the human performance using a master-slave manipulator, the da VinciTM System. Herein, we report our initial experience of employing robotic telepresent technology to perform a LRP. MATERIALS AND METHODS: A 6-port modified transperitoneal approach was used. The da VinciTM System (Intuitive Surgical, Inc., California) consists of three components: a surgeon console, a robotic manipulator and a vision cart. Cable-driven mechanical "Endowrist" instruments are capable of delivering a complete range of motion at the instrument tips, allowing a total of 6 degrees of freedom. RESULTS: Five robotic-assisted LRP were performed. The mean patient age PSA and Gleason score were 65 years, 7.8ng/ml and 6.2, respectively. Overall, the system functioned well, without significant intraoperative errors. The mean operative time was 185 minutes in 2 patients with preservation of the neurovascular bundle, and 154 minutes in 2 patients with non-nerve sparing. In one patient, a bilateral pelvic lymphadenectomy was performed, with an operative time of 195 minutes. The mean blood loss and hospital stay were 245cc and 2.5 days, respectively. All patients maintained continence at 3 month follow-up. CONCLUSIONS: Intuitive hand-eye coordination, superb depth of perception and "Endowrist" instruments allowed tissue handling and suturing quite feasible during the LRP. Continuous effort is underway to further the surgical experience and advances in robotic technology. We believe robotic surgical systems will greatly facilitate and improve the LRP procedure.

For over a half centry, physicians have suspected that patients with duodenal ulcer are offered an insurance policy against gastric carcinoma. This may be used clinically so that gastric lesion in the presence of duodenal ulcer, are considered benign. However, the duodenal ulcer may coexit with gastric cancer, Although rare in incidence of coexistence of duodenal ulcer and gastric cancer, physician always should be alert in diagnosing of gastric lesion in the presence of the duodenal ulcer. Here, we present 60 years old woman with coexitence of duodenal ulcer and gastric cancer, diagnosed by endoscopy and treated surgically.

BACKGROUND: A mixture of local anesthetics such as lidocaine and bupivacaine has frequently been used in clinical practice. The rationale behind this is to take advantage of lidocaine's rapid onset and bupivacaine's perpetuation in anesthesia. The purpose of this study was to examine the changes in the onset and recovery of nerve blocking action exerted by the different combinations of these two in the mixture. METHODS: Isolated sciatic nerve preparations obtained from adult male Sprague-Dawley rats were used in this study. Recordings of A-fiber compound action potentials (A-CAPs) were made at the end of the isolated nerve while single pulse stimuli (0.5 msec, supramaximal intensity, 2 Hz) were applied to the opposite end of the nerve. Seven different composition of lidocaine-bupivacaine mixtures were prepared (0 : 6, 1 : 5, 2 : 4, 3 : 3, 4 : 2, 5 : 1, 6 : 0 vol./vol.), where basal concentrations of lidocaine and bupivacaine were 0.2% and 0.05%, respectively. Amplitudes of A-CAPs were measured before, during and after perfusion of mixture solution. The time needed for A-CAPs amplitude to decrease to 10% of the basal value after starting perfusion (onset time) and that needed to reach to 50% of the basal value after ceasing the perfusion (recovery time) were measured. RESULTS: With increasing concentration ratios of lidocaine to bupivacaine in the mixture as mentioned above, the following onset and recovery times were obtained (6.0 +/- 0.3, 5.6 +/- 0.3, 6.0 +/- 0.5, 8.3 +/- 0.5, 7.3 +/- 0.6, 7.8 +/- 0.3, and 10.8 +/- 0.8, minutes; 38 +/- 4, 63 +/- 12, 87 +/- 19, 100 +/- 13, 104 +/- 18, 137 +/- 27, and 157 +/- 18 minutes, respectively). CONCLUSION: Onset times were, in general, exponentially decreased with the increase in the lidocaine concentration. However, recovery times were lineary increased with the increase in the bupivacaine concentration. So, it should be kept in mind that rapid onset can only be obtained with the expense of substantial reduction in the duration of local anesthetic effect of the mixture, and vice versa.
