Brain Spine

August 2024

Department of Neurosurgery, Fondazione I.R.C.C.S. Istituto Neurologico "C. Besta", Milano, Italy.

Article Synopsis
  • Neurosurgery requires not only technical skills but also non-technical skills (NTSs) to achieve mastery, highlighting the importance of both in surgical practice.
  • An international survey of 372 neurosurgeons indicates that qualities like attention to detail, humility, and self-awareness are vital for surgical precision and effective teamwork.
  • The study advocates for integrated training that includes simulations and mentorship to enhance NTSs, while also stressing the need for research aimed at improving educational methods, especially in regions with unequal access to neurosurgical care.

Objective: Common peroneal (fibular) neuropathy is the most common mononeuropathy of the lower extremity. Despite this, there are surprisingly few studies on the topic, and a knowledge gap remains in the literature. As one attempts to address this knowledge gap, a core outcome set (COS) is needed to guide the planning phases of future studies to allow synthesis and comparability of these studies.

Effects of COVID-19 Pandemic in Patients with a Previous Phrenic Nerve Transfer for a Traumatic Brachial Plexus Palsy.

J Brachial Plex Peripher Nerve Inj

January 2024

Division of Reconstructive Microsurgery, Department of Plastic and Reconstructive Surgery, Chang Gung Memorial Hospital, Chang Gung University, Taoyuan, Taiwan.

 With the advent of the coronavirus disease 2019 (COVID-19) pandemic, some doubts have been raised regarding the potential respiratory problems that patients who previously underwent a phrenic nerve transfer could have.  To analyze the effects of the coronavirus infection on two populations, one from Argentina and another from Taiwan. Specific objectives were: (1) to identify the rate of COVID in patients with a history of phrenic nerve transfer for treatment of palsy; (2) to identify the overall symptom profile; (3) to compare Argentinian versus Taiwanese populations; and (4) to determine if any phrenic nerve transfer patients are at particular risk of more severe COVID.

Attempts at body contour modifications have led to the use of different alloplastic materials that can irreversibly damage health and risk patients' lives. These modeling substances can induce a general autoimmune inflammatory response, producing a very heterogeneous clinical spectrum ranging from mild and severe systemic to local symptoms that sometimes affect peripheral nerves. We report a unique case of a tumor-like sciatic nerve impairment produced months after the injection of a modeling substance into the buttocks for esthetic purposes.

Article Synopsis
  • Ventriculoperitoneal shunt (VPS) is a common treatment for hydrocephalus in children, but rare complications like the catheter migrating and coming out through the rectum can occur, leading to serious issues without warning symptoms.
  • A 9-month-old infant with a history of prematurity and tuberculous meningitis presented with the distal end of their VPS catheter visible at the rectum for a week, but showed no neurological or gastrointestinal symptoms, prompting immediate surgical intervention.
  • The case highlights the importance of considering unusual complications in VPS patients, as well as the need for vigilant monitoring, especially in asymptomatic infants to prevent life-threatening outcomes.

Article Synopsis
  • - The study aimed to compare brain plasticity between two groups with brachial plexus palsies: newborns (NBPP) and adults (NNBPP) who underwent nerve transfers, using the plasticity grading scale (PGS).
  • - A total of 153 NNBPP patients and 35 NBPP babies were included, revealing that babies scored higher on the PGS after surgery compared to adults, indicating better brain rewiring in infants.
  • - The results showed that while both groups had similar rehabilitation compliance, newborns displayed significantly greater potential for brain plasticity than adults, making them more capable of recovering function after nerve transfers.

Article Synopsis
  • Ulnar and median nerve transfers to the musculocutaneous nerve (MCN) are performed to help restore elbow flexion in patients with severe brachial plexus injuries, but the impact of patient age on brain plasticity during recovery is unclear.
  • In a study with 66 patients divided into neonatal (NBPP) and nonneonatal (NNBPI) groups, the results showed that all NBPP patients achieved a high level of control (PGS grade of 4), while only 47.7% of NNBPI patients reached the same level.
  • Age was found to be a significant predictor of plasticity, indicating that younger patients (like those with NBPP)

Injuries (rupture, avulsion) of the triceps tendon are considered infrequent injuries, which mainly affect the male gender and are directly associated with injuries that occur during sports and in a high percentage due to the consumption of steroids. The diagnosis and treatment must be carried out early, especially in those patients with high functional demand or elite athletes, in order to obtain good functional results. The clinical examination should be accompanied by diagnostic imaging studies.

Introduction: The phrase "think globally, act locally", which has often been used to refer to conservation of the environment, highlights the importance of maintaining a holistic perspective and stipulates that each individual has a role to play in their community and larger world. Although peripheral nerve surgery has been largely unemphasized in global neurosurgical efforts, a wide disparity in peripheral nerve surgery is presumed to exist between high-income and low- and middle-income countries. Serbia is an upper middle-income country with a long history of peripheral nerve surgery.
