Background: Radiation therapy (RT) is a longstanding treatment modality for cancer. In addition, immune checkpoint blockade has been a significant development in the field of immunotherapy, modifying key immunosuppressive pathways of cancer cells. Methods: The aim of the present work was to review current concepts of RT and immunotherapy synergism, the abscopal effect, and the molecular effects of RT in the tumour microenvironment, its influence on immune stimulation, and potential clinical outcomes that might evolve from ongoing studies. We also discuss potential predictors of clinical response. Results: Up-to-date literature concerning the mechanisms, interactions, and latest knowledge about RT and immunotherapy was reviewed and summarized, and is presented here. Conclusions: The possibility of using hyperfractionated RT to combine an abscopal effect with the enhanced effect of immune treatment using checkpoint blockade is a very promising method for future tumour treatments.
Background and purpose: Classic Kaposi sarcoma (CKS) is a rare vascular disease mainly found in populations of Mediterranean origin. The pathogenesis involves Human Herpes Virus 8 (HHV8) and genetic mutations such as SNP309 in the MDM2 gene. The recently discovered BPTF mutation in cells of CKS patients demonstrated higher latency-associated nuclear antigen (LANA) staining and altered vital transcriptomics, implicating a potential role in tumorigenesis. This review explores the genetic underpinnings and treatments for CKS. Material and methods: A comprehensive literature search was conducted from 2004 to 2024, yielding 70 relevant papers. Ongoing clinical trials investigating novel treatments such as talimogene and abemaciclib were included in the search and presented in the results. Results: Clinical diagnosis and treatment can be challenging as the number of studies on CKS and treatment modalities is limited. Treatment strategies vary by disease stage, with local therapies like surgical intervention and radiation therapy recommended for early stages, while systemic therapies are considered in cases of systemic disease. Interpretation: While advancements in CKS treatment offer hope, further studies on immunotherapy are warranted to broaden the therapeutic options, such as anti-bromodomain or BPTF-targeted therapy.

Cervical cancer is the fourth-most common type of cancer and cause of death in women. Human papilloma virus (HPV) infection is responsible for over 90% of cervical cancers. The recommended treatment is multidisciplinary, consisting of a combination of surgery, chemotherapy, and radiation therapy. The standard treatment in advanced stages, such as FIGO IIIb, is radio-chemotherapy with overall 5-year survival of 32%. Photofrin II has been demonstrated to serve as a specific and selective radiosensitizing agent in both in vitro and in vivo tumor models, admitted for radiation therapy. We describe a patient with advanced cervical carcinoma (squamous cell) who contacted us for further therapy in 2003. Staging included a gynecological examination, colonoscopy, explorative laparotomy, biopsy and pelvic MRI. The explorative laparotomy showed enlarged pelvic and para-aortal lymph nodes. The histologic examination described tumor infiltrated, positive lymph nodes (Stage FIGO IIIb). Contrary to recommendations, the patient refused standard treatment with a combination of chemotherapy and radiotherapy, but accepted a combined treatment of Photofrin II as a radiosensitizer and a radiotherapy procedure. She underwent irradiation with a 50.4 + 14 Gy boost with fractionation of 1.8 Gy day−1 for 5 days per week; the boost was given with 2 Gy fractions. She was injected with a single intravenous dose in a slow infusion (30 min) of 1 mg kg−1 of Photofrin II 24 h prior to radiation therapy. A localized relapse in the cervix appeared after 30 months, and was resected by hysterectomy. The patient is still alive with no evidence of disease after 15 years.
Plate breakage is one form of construct failure after a clavicle fracture treated with an open reduction and plate fixation. A recent study evaluated construct failure after an open reduction and plate fixation and reported a construct failure rate of 6.9% of which 1.9% were related to broken plates. Plate breakage is rare, thus, there are insufficient data regarding risk factors, pathogenesis, or how to avoid it. This case report presents an unusual case of a 35-year-old Caucasian man, 7 weeks after open reduction and internal plate fixation of a fracture in the middle third of his clavicle, who developed breakage of the implant. Surgery was advised, the implant was retrieved, the fracture was reduced, and a new bridging locking plate was implanted. In the current case it seems that the use of a bridging plate, the fundamental anatomical structure of the clavicle and the forces that are applied on it, the lack of discipline in complying with the postoperative functional restrictions, and an unclear “patient expectation” process were the main reasons for the failure. These aspects should be carefully considered and addressed in clavicle fractures.
Background: The COVID-19 pandemic has impacted nursing theatre staff, departmental activity, and delivery of services to patients. This work-based project aimed to investigate the challenges of nursing leadership in an elective orthopaedic department at current times. Methods: The study collected qualitative data exploring theatre staff’s expectations from leadership, offering insight on how the pandemic has influenced the way of working and exploring how the future in this unit may look. The answers from 20 practitioners to an anonymised open-ended survey were examined using thematic analysis. Results: The participants described a leader as a good communicator who focuses on empowering others and supporting the team, identified by the majority as a senior team member. From the findings, three topics were identified: immediate changes, delayed changes, and pre-existing conditions. The answers painted a reality that is complex and multifaceted, where numerous variables play a part in the physical and mental health of each candidate, impacting their performance as well as their work/life balance. Overall, the strongest subjects recurring in the findings were the need for nursing leadership to focus on supporting staff with training opportunities, to actively plan for a reduction in staffing shortages, and to be constantly mindful of staff well-being. Conclusions: This study pointed out that the need for constant communication with their staff, building honest relationships, and being a reliable leader, focused on empowering others and supporting the team were important factors for the nursing management during the COVID-19 pandemic and post-COVID-19 era.
Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common, often debilitating side effect of several chemotherapeutic agents, particularly taxanes and platinum compounds. Current management strategies remain limited, with few agents demonstrating consistent efficacy. Our aim was to evaluate the efficacy and safety of a novel topical cream containing 1% amitriptyline and 0.5% ketamine in alleviating CIPN symptoms in oncology patients. Methods: A prospective observational study was conducted at Barzilai Medical Center following the approval of the local ethics committee. Thirty-seven patients (30 females, 7 males; age 40–75) with CIPN following taxane or platinum-based chemotherapy were treated with a topical cream applied three times daily for 28 weeks. Pain intensity was assessed using the Visual Analog Scale (VAS). Inclusion and exclusion criteria were strictly applied to ensure a homogenous cohort. Results: Initial mean VAS was 7 (range 6–10), which decreased to a final mean VAS of 3 (range 1–7). Two patients withdrew from the study, and 27 out of 35 evaluable patients (77.14%) reported significant symptoms relief. A statistically significant reduction in pain scores (p = 0.00005) was seen in our study. Only mild, transient erythema was reported as a side effect. Conclusions: This is the first clinical evaluation of a topical combination with new concentrations of amitriptyline and ketamine for CIPN. The results suggest this formulation offers a safe and effective option for symptomatic relief. Larger randomized controlled trials and exploration of transdermal delivery systems are warranted to validate these findings and optimize treatment outcomes.
