Solitary plasmacytomas are localized single tumors of monoclonal plasma cells that occur in two variants: solitary plasmacytoma of bone and extraosseous plasmacytoma. Solitary plasmacytoma of bone accounts for only 1%-2% of plasma cell lesions, and extraosseous plasmacytoma is also approximately 1%. These are both very uncommon at the skull base.

Introduction: The nasoseptal flap (NSF) has become a widely favoured choice for reconstructing skull base defects following the endoscopic endonasal approach (EEA). However, the exposed septal cartilage and bone at the donor site often require an extended duration for secondary healing. This study investigated whether the free middle turbinate (MT) mucosa grafting at the septal donor site could mitigate post-operative nasal morbidity.

An 18-year-old female patient presented with a 1-month history of low back pain, which had worsened and was accompanied by radiating pain in the right lower limb for half a month. She was admitted to our hospital with computed tomography and magnetic resonance imaging findings suggesting calcification of the L3/4 disc and a large intraspinal mass at the L2-4 level. The patient's symptoms did not improve with conservative treatment, and her muscle strength rapidly declined.

Hypomanic personality traits (HPT) are susceptibility markers for psychiatric disorders, particularly bipolar disorder, and are strongly associated with aggressive behaviors. However, the neuropsychological mechanisms underlying this association remain unclear. This study utilized psychometric network analysis and (IS-RSA) to explore the neuropsychological circuits that link HPT to aggression in a large non-clinical population.

Wearable augmented reality in neurosurgery offers significant advantages by enabling the visualization of navigation information directly on the patient, seamlessly integrating virtual data with the real surgical field. This ergonomic approach can facilitate a more intuitive understanding of spatial relationships and guidance cues, potentially reducing cognitive load and enhancing the accuracy of surgical gestures by aligning critical information with the actual anatomy in real-time. This study evaluates the benefits of a novel AR platform, VOSTARS, by comparing its targeting accuracy to that of the gold-standard electromagnetic (EM) navigation system, Medtronic StealthStation S7.

Background: Although more risk prediction models are available for feeding intolerance in enteral-nourishment patients, it is still unclear how well these models will work in clinical settings. Future research faces challenges in validating model accuracy across populations, enhancing interpretability for clinical use, and overcoming dataset limitations.

Objective: To thoroughly examine studies that have been published on feeding intolerance risk prediction models for enteral nutrition patients.

Background: Each year, nearly 400,000 new cases of paediatric hydrocephalus are estimated to occur worldwide, and almost half of these cases are expected to affect children in Africa. At Queen Elizabeth Central Hospital (QECH), an urban tertiary hospital in Blantyre, Malawi, located in south-east Africa, around 200 children received neurosurgical treatment for hydrocephalus in 2023. These children require lifelong follow-up and care, which places significant demands on their caregivers.

Introduction: Intraoperative microelectrode recording (MER) and intraoperative test stimulation may provide vital information for optimal electrode placement and clinical outcome in movement disorders patients treated with deep brain stimulation (DBS). The aims of this retrospective study were to determine (i) how often the planned (imaging based) placements of electrodes were changed due to MER and intraoperative test stimulation in Parkinson's disease (PD), dystonia and essential tremor (ET) patients; (ii) whether the frequency of repositioning changed over time; (iii) whether patients' age or disease duration (in PD) influenced the frequency of repositioning.

Methods: Data on the planned and the final placement of 141 electrodes in 72 consecutive DBS treated patients (52 PD, 11 dystonia, 9 ET) was collected over the first 8 years of DBS implementation in a single center.

Background: The learning environment (LE) plays a crucial role in the performance and training of medical students. Different tools have been used to assess the LE with various conclusions. However, the John Hopkins Learning Environment Scale (JHLES) which is a relatively newer scale is more specific, less cumbersome to administer, and has a wider scope.

Purpose: Therapeutic options for patients with brain metastases (BM) increase. While these lead to considerable survival effects in subgroups, there is limited knowledge about characteristics, prognosticators and treatment effects in patients with BM and short survival.

Methods: Patients with a survival time of ≤ 6 months (short-term survivors, STS), diagnosed with BM between 2009-2021 at a large tertiary cancer center were analysed.

Hepatic ischemia-reperfusion (I/R) injury frequently occurs during the perioperative phase of liver surgery. Inappropriate activation of STING signaling can trigger excessive inflammation response to aggravate hepatic I/R injury. Dimethyl fumarate (DMF) is an FDA-approved immunomodulatory drug used to treat multiple sclerosis and psoriasis due to its notable anti-inflammation properties.

Glioblastoma multiforme (GBM) is a tumor with a high refractory rate to immunotherapy and a low tumor mutational burden phenotype, leading to limited immunogenic neoantigens. The present study aimed to investigate the sequential use of immunotherapy and bevacizumab in patients with GBM, exploring the clinical outcomes and potential complications. Patients received various combinations of immunotherapy and bevacizumab after standard treatment, including surgery, radiotherapy and temozolomide.

The aim of this study is to describe the management and evolution of a patient with the rare condition of double lactotroph tumors and assess the role of intraoperative ultrasonography (IOUS) for their detection and methylation-based liquid biopsy for their diagnosis and monitoring. A 29-year-old woman diagnosed with double lactotroph tumors through hormonal and MRI workup underwent surgical resection due to cabergoline intolerance. To detect a tumor missing through visual inspection, IOUS was performed.

This study was conducted to investigate whether the addition of photobiomodulation therapy (PBMT) to pelvic floor exercises (PFEs) is more effective in treating postpartum coccydynia compared with either modality alone. Postpartum coccydynia is a widespread condition that significantly affects the quality of life. Inflammation as a response to childbirth trauma and weakening of the muscles and ligaments attached to the coccyx are presumed causes of postpartum coccydynia.
