Brachial plexus injuries (BPIs) caused by shoulder dislocation usually have a transient character and tend to resolve spontaneously. However, in some patients the symptoms can persist and require operative intervention. This work aims to determine the risk factors for persistent BPIs resulting from shoulder dislocation. The study comprised 73 patients (58 men, 15 women; mean age: 50 years) treated operatively between the years 2000 and 2016 for persistent BPIs resulting from shoulder dislocation. Patient age, gender, type of initial trauma, number of affected nerves, presence of accompanying injuries, and time interval from dislocation to its reduction were analysed...

OBJECTIVE: Chordomas are rare tumors of notochordal origin that are known to be locally aggressive and are often treated with surgical resection followed by adjuvant radiotherapy. The accepted standard of treatment for chordomas of the mobile spine which includes en-bloc resection with wide margins cannot be easily applied to the chordomas of the skull base given their proximity to critical neurovascular structures. We describe our experience with the role of surgery and adjuvant radiation in the treatment of chordomas over 16 years...

Background: Electrical stimulation is increasingly relevant in a variety of medical treatments. In this study, surface electrical stimulation was evaluated as a method to non-invasively target a neural function, specifically natural sensation in the distal limbs. Method: Electrodes were placed over the median and ulnar nerves at the elbow and the common peroneal and lateral sural cutaneous nerves at the knee. Strength-duration curves for sensation were compared between nerves...

Introduction: Sleep and migraine share a common pathophysiological substrate, although the underlying mechanisms are unknown. The serotonergic and orexinergic systems are both involved in the regulation of sleep/wake cycle, and numerous studies show that both are involved in the migraine etiopathogenesis. These two systems are anatomically and functionally interconnected. Our hypothesis is that in migraine a dysfunction of orexinergic projections on the median raphe (MR) nuclei, interfering with serotonergic regulation, may cause Non-Rapid Eye Movement parasomnias, such as somnambulism...

Transection of the median nerve typically causes lifelong restriction of fine sensory and motor skills of the affected hand despite the best available surgical treatment. Inspired by recent findings on activity-dependent structural plasticity of the adult brain, we used voxel-based morphometry to analyze the brains of 16 right-handed adults who more than two years earlier had suffered injury to the left or right median nerve followed by microsurgical repair. Healthy individuals served as matched controls. Irrespective of side of injury, we observed gray matter reductions in left ventral and right dorsal premotor cortex, and white matter reductions in commissural pathways interconnecting those motor areas...

Background: Radiological biomarkers which correlate with visual function are needed to improve the clinical management of optic pathway glioma (OPG) patients. Currently, these are not available using conventional magnetic resonance imaging (MRI) sequences. The aim of this study was to determine whether diffusion MRI could be used to delineate the entire optic pathway in OPG patients, and provide imaging biomarkers within this pathway which correlate with a patient's visual acuity (VA)...

PURPOSE: Resection of a long rectal stump after previous colectomy or Hartmann procedure often requires a combined transperitoneal and transperineal approach because of limited access through a perineal incision alone. Risks associated with this procedure include iatrogenic injury to bowels, nerves, ureters, vessels and sexual organs. This study reports on the feasibility and safety of perianal minimally invasive surgery (PAMIS) for the resection of long rectal stumps that would otherwise require a combined transperitoneal and perianal approach...

Some children suffering from chronic abdominal pain may have an abdominal wall entity such as anterior cutaneous nerve entrapment syndrome. This syndrome is largely suspected on a combination of findings at history and physical examination. The aim is to obtain clues in history and physical examinations in a selected population of children with anterior cutaneous nerve entrapment syndrome. We analyzed all children with abdominal pain visiting our hospital between January 2013 and January 2015. A total of 71 cases were identified (median age 15 years, range 8-17, 77% female)...
