Background and Study Aims There is a paucity of literature on beginners' training and on its connection with patient safety for transforaminal epidural steroid injections (TFESIs). This study retrospectively assessed the learning curves and associated complications of neurosurgery residents never previously exposed to TFESI and compared them with experienced board-certified faculty neurosurgeons (BCFNs). Material and Methods Procedure time in minutes, dose-area product (DAP) in cGy*cm(2), periprocedural observations, and complications in 354 TFESIs for radicular pain secondary to lumbar disk herniation or lumbar spinal stenosis were extracted from operative notes and the electronic infiltration logbook in the per-injection format...

Here is a life in three countries, with different cultures, different political structures and even different skies. The constant through all these changes is the addiction of the subject of this story to science and laboratory work. Perhaps the tale that unfolds here will show to some beginners in research that persistence, seasoned with a little luck, can bring results and satisfaction in the long run.

Golfers may injure themselves as a result of repetitive asymmetrical loads exerted on the body by poor swing mechanics. If the repetitive sub-maximal loading is not removed, this repetitive loading will exceed the adaptive capacity of bone, eventually resulting in a stress fracture. Stress fracture of the scapula due to golfing is extremely rare. Only two cases of acromion fracture have been reported. A rare case of nontraumatic coracoid fracture in a 50-year-old female beginner golfer is reported here. The mechanism of injury is also discussed...

Background Observation is mentioned in most ethnographic textbooks, but specific details about how it should be conducted and the practicalities to be considered in ethnographic nursing research are not always explicit. This paper explores the experiences of and challenges faced by a novice nurse researcher who used observation to collect data. Aim To provide a novice researcher's perspective of observation in ethnographic nursing research and to highlight the associated challenges. Discussion Challenges that arose in observation began with determining which perspective to take, followed by rehearsing observation, developing and maintaining a constructive relationship with the observation site, being aware of the influence of the observer, managing interactions between the observed and the observer, and responding to ethical issues...

INTRODUCTION: Physical and mental changes associated with aging commonly lead to a decrease in communication capacity, reducing social interactions and increasing loneliness. Computer classes for older adults make significant contributions to social and cognitive aspects of aging. Games in a virtual reality (VR) environment stimulate the practice of communicative and cognitive skills and might also bring benefits to older adults. Furthermore, it might help to initiate their contact to the modern technology...

Jin Woong Kim, Sang Soo Shin
Ultrasound-guided percutaneous core needle biopsy (USPCB) is used extensively in daily clinical practice for the pathologic confirmation of both focal and diffuse diseases of the abdominal viscera. As a guidance tool, US has a number of clear advantages over computerized tomography or magnetic resonance imaging: fewer false-negative biopsies, lack of ionizing radiation, portability, relatively short procedure time, real-time intra-procedural visualization of the biopsy needle, ability to guide the procedure in almost any anatomic plane, and relatively lower cost...

Santiago Casado
Controlling the stick-slip friction phenomenon is of major importance for many familiar situations. This effect originates from the periodic rupture of junctions created between two rubbing surfaces due to the increasing shear stress at the interface. It is ultimately responsible for the behavior of many braking systems, earthquakes, and unpleasant squeaky sounds caused by the scratching of two surfaces. In the case of a musical bow-stringed instrument, stick-slip is controlled in order to provide well-tuned notes at different intensities...

This chapter deals with the employment of human-induced pluripotent stem cells (hiPSCs) as a candidate to differentiate into mesenchymal stem cells (MSCs). This would enable to help establish a regular source of human MSCs with the aim of avoiding the problems associated with procuring the MSCs either from different healthy individuals or patients, limited extraction potentials, batch-to-batch variations or from diverse sources such as bone marrow or adipose tissue. The procedures described herein allow for a guided and ensured approach for the regular maintenance of hiPSCs and their subsequent differentiation into MSCs using the prescribed medium...

Chandrakant Rambhau Gharwade
Follicular unit extraction (FUE) is one of the widely practiced minimally invasive follicular harvesting techniques employed during hair transplantation. FUE technique has an advantage of utilising lower occipital area and supra-auricular region as a safe donor area described by Unger, in addition to the standard occipital donor area used in strip method (follicular unit transplant). Despite its potential advantages such as rapid recovery, minimal scarring and reduced post-operative pain; its widespread acceptance is limited due to various factors in variable contribution like steeper learning curve and potentially higher follicular transection rates (FTRs)...

BACKGROUND AND OBJECTIVE: Progress in endoscopic surgery in the past few decades has led to the application of 3-dimensional (3D) procedures in operating rooms. This permits patient- and surgeon-friendly operations and also maximizes the superiority of laparoscopy over laparotomy. In this study, we compare 2-dimensional (2D) and 3D endoscopy techniques with regard to time, efficiency, optics, and handling by users with different degrees of experience at 4 difficulty levels. DESIGN: A randomized controlled trial on a pelvitrainer in objectively graded surgical steps for students and postgraduates...

The Topographic Attentive Mapping (TAM) network is a biologically-inspired classifier that bears similarities to the human visual system. In case of wrong classification during training, an attentional top-down signal modulates synaptic weights in intermediate layers to reduce the difference between the desired output and the classifier's output. When used in a TAM network, the proposed pruning algorithm improves classification accuracy and allows extracting knowledge as represented by the network structure...
