One of the main limitations to successful long-term use of peritoneal dialysis (PD) as a renal replacement therapy is the harmful effects of PD solutions to the structure and function of the peritoneal membrane (PM). In PD, the PM serves as a semipermeable membrane that, due to exposure to PD solutions, undergoes structural alterations, including peritoneal fibrosis, vasculopathy, and neoangiogenesis. In recent decades, oxidative stress (OS) has emerged as a novel risk factor for mortality and cardiovascular disease in PD patients. Moreover, it has become evident that OS plays a pivotal role in the pathogenesis and development of the chronic, progressive injury of the PM. In this review, we aimed to present several aspects of OS in PD patients, including the pathophysiologic effects on the PM, clinical implications, and possible therapeutic antioxidant strategies that might protect the integrity of PM during PD therapy.

Incorporation of radiology into anatomy education is a frequently used teaching strategy. Our purpose was to investigate to what extent virtual reality can play a significant role when radiology is taught in conjunction with anatomy. PubMed, SCOPUS, Education Resources Information Center, and Cochrane databases were searched for articles with the aim to evaluate the outcomes of incorporation of radiology in anatomy education, using virtual reality. From each included paper, the following data were extracted: authors, number of participants, type of study (comparative or not), level of outcome according to Kirkpatrick hierarchy, and outcomes of the use of virtual reality when radiology was incorporated in anatomy education. Seven papers were included. From them, three were comparative and evaluated students’ academic performance after the educational intervention, while four were non-comparative and evaluated only students’ opinions about the intervention. In all studies, the use of virtual reality for the incorporation of radiology into anatomy teaching was positively perceived. Also, the three studies which evaluated academic performance showed that virtual reality was effective in terms of enhancing anatomy knowledge. The implementation of virtual reality for the incorporation of radiology into anatomy education has been accompanied by positive outcomes. These outcomes may encourage educators to teach radiology in conjunction with anatomy using virtual reality.

Bipolar clavicle dislocation is thought to be a rare injury pattern. Even experienced orthopaedic surgeons may have not come across this entity during their careers. We report a misdiagnosed case of a 65-year-old male who underwent a motorcycle accident and was surgically treated six months post-injury. This case has been the ground for research since then. We have come to the conclusion that this type of injury is probably not so uncommon as previously thought. Careful evaluation is of immense importance during diagnosis protocol, and practitioners should be aware of this injury pattern in order to avoid misdiagnosis.

The treatment of painful and chronic dislocated hip in children with severe cerebral palsy (CP) is particularly demanding and controversial. Numerous surgical techniques have been described, and their outcomes vary a lot. The purpose of the present study is to evaluate a new method, which combines varus derotational subtrochanteric osteotomy (VDSO) and external osteosynthesis: (VDSOEO). Six non-ambulatory children with spastic quadriplegia and chronic dislocated painful hips were treated. The technique involved a small incision on the subtrochanteric site of the osteotomy, followed by retention with a single-sided external osteosynthesis with rotational correction capability [swiveling clamp (SC)] for the reduction of the femur head in the acetabulum, and finally by the osteotomy. Hardware was removed without a second intervention four-six months postoperatively and after the osteotomy was healed. Evaluation of the method was based on clinical, functional, and radiological criteria. Four patients achieved improved radiological scores. Two patients demonstrated resubluxation during the period of the osteotomy's healing process. However, no patients experienced pain, and all were able to sit post-surgery, while caregivers reported improved capacity for nursing care. It is our strong belief that this approach can improve the quality of life in children with severe CP and painful and chronic dislocated hips. It is a viable and definitely less invasive procedure than classic pelvic or femur osteotomies.
