Pain is an unpleasant feeling that has been shown to be an important factor for the recovery of patients. Since this is costly in human resources and difficult to do objectively, there is the need for automatic systems to measure it. In this paper, contrary to current state-of-the-art techniques in pain assessment, which are based on facial features only, we suggest that the performance can be enhanced by feeding the raw frames to deep learning models, outperforming the latest state-of-the-art results while also directly facing the problem of imbalanced data...

Inability to cross the lesion with a guidewire is the most common reason for failure in percutaneous revascularization (PCI) of chronic total occlusions (CTOs). An ostial or stumpless CTO is an acknowledged challenge for CTO recanalization due to difficulty in successful wiring. IVUS imaging provides the opportunity to visualize the occluded vessel and to aid guidewire advancement. We review the value of this technique in a single-centre experience of CTO PCI. This series involves 22 patients who underwent CTO-PCI using IVUS guidance for stumpless CTO wiring at our institution...

Robotic surgery is a conceptual fusion of the conventional open surgery and the minimally invasive laparoscopic surgery. We reviewed the current role of robotic-assisted laparoscopy in the field of reproductive surgery by a literature search in PubMed database. We analyzed the reported advantages and limitations of the use of robotics in reproductive surgeries like myomectomy, tubal reanastomosis, endometriosis, ovarian tissue cryopreservation, and ovarian transposition. Overall, robotic assistance in reproductive surgery resulted in decreased blood loss, less post-operative pain, shorter hospital stay, and faster convalescence, whereas reproductive outcomes were similar to open/laparoscopic approaches...

BACKGROUND/AIM: Cecal intubation using conventional colonoscopy (CC) requires substantial training. We hypothesized that double-balloon colonoscopy (DBC) facilitates cecal intubation by endoscopy naïve operators. The aim of this study is to evaluate the cecal intubation rate and learning curve of DBC compared with CC. METHODS: Eighteen endoscopy naïve medical students were allocated to two groups and attempted cecal intubation within 20 min using a colon simulator...

The purpose of this study was to assess the accuracy of femoral tunnel placement in a medial patellofemoral ligament reconstruction (MPFL-R) cohort. The secondary purpose was to establish the evidence of a learning curve to achieve acceptable femoral tunnel placement during MPFL-R. Two surgeons, using lateral radiographs, assessed 73 subjects post-MPFL-R. Femoral tunnel accuracy and direction of tunnel error were measured in relation to Schöttle's point (A-T distance). Interrater reliability (intraclass correlation coefficient 2,k) of these measures was calculated...

The interaction between pain and the motor system is well-known, with past studies showing that pain can alter corticomotor excitability and have deleterious effects on motor learning. The aim of this study was to better understand the cortical mechanisms underlying the interaction between pain and the motor system. Experimental pain was induced on 19 young and healthy participants using capsaicin cream, applied on the middle volar part of the left forearm. The effect of pain on brain activity and on the corticomotor system was assessed with electroencephalography (EEG) and transcranial magnetic stimulation (TMS), respectively...
