Honorary authorship in high-impact journals in anaesthesia and pain medicine.

Enlisting an author on a published paper, whose input was insufficient, is called honorary authorship. The aim of this study is to assess the proportion of honorary authorship in the field of pain medicine. Data were collected from seven high-impact journals. Corresponding authors were sent a survey regarding their awareness on authorship guidelines, the decision-making in authorship and specific contributions made to the surveyed article. We identified two types of honorary authorship: (1) self-perceived honorary authorship, which is measured by asking the corresponding author if honorary authorship was present according to their opinion and (2) International Committee of Medical Journal Editors (ICMJE)-defined honorary authorship, which is honorary authorship based on the guidelines. In total, 1051 mails were sent and 231 responded, leading to a response rate of 22.0%. 81.3% of the respondents were familiar with the ICMJE authorship guidelines, while 59.6% were aware of the issue of honorary authorship. 13.3% of the respondents were employed at a department in which the senior member is automatically included on all manuscripts. The ICMJE-defined honorary authorship was 40%, while self-perceived honorary authorship was 13.5%. There seems to be a high awareness of the ICMJE guidelines among corresponding authors in the field of Pain Medicine. Despite this high awareness, a high proportion of journal articles had honorary authorship, suggesting that authorship guidelines fail to be applied in a significant proportion of the literature.

Mistreatment, discrimination and burn-out in Neurosurgery.

OBJECTIVE: Issues concerning harassment, bullying and discrimination are not unknown to medical specialties and are likely to be present in neurosurgery as well. The aim of this study was to estimate the extent to which neurosurgeons are faced with issues pertaining to this mistreatment. METHODS: A survey consisting of fourteen questions was distributed among members of the Congress of Neurological Surgeons (CNS). The survey consisted of three parts: 1) demographics; 2) exposure to mistreatment; 3) experienced burnout symptoms. RESULTS: In total 503 out of the 5665 approached CNS members filled in a survey (response rate 8.9 %). Respondents consisted for 85.9 % out of neurosurgeons and for 13.9 % out of residents. Overall, 61.4 % of the respondents was a victim of form of abusive behavior, while 47.9 % was a victim of at least one form of discrimination. Most reported sources of these mistreatments were other neurosurgeons or (family of) patients. Overall, 49.9 % of the respondents experienced burnout symptoms. Multivariable logistic regression analysis showed that female respondents had higher odds of being a victim of abuse (OR 2.5, 95 % CI 1.4-4.6). Female respondents (OR 19.8, 95 % CI 8.9-43.9) and ethnic minorities (OR 3.8, 95 % CI 2.3-6.2) had higher odds of being a victim of discrimination. Furthermore, victims of abuse were at higher odds (OR 1.7, 95 % CI 1.1-2.6) of having burnout symptoms. CONCLUSIONS: Mistreatment and experiencing burnout symptoms frequently occurs among neurosurgeons and residents.

The Dorsal Root Ganglion as a Novel Neuromodulatory Target to Evoke Strong and Reproducible Motor Responses in Chronic Motor Complete Spinal Cord Injury: A Case Series of Five Patients.

OBJECTIVES: Current strategies for motor recovery after spinal cord injury (SCI) aim to facilitate motor performance through modulation of afferent input to the spinal cord using epidural electrical stimulation (EES). The dorsal root ganglion (DRG) itself, the first relay station of these afferent inputs, has not yet been targeted for this purpose. The current study aimed to determine whether DRG stimulation can facilitate clinically relevant motor response in motor complete SCI. MATERIALS AND METHODS: Five patients with chronic motor complete SCI were implanted with DRG leads placed bilaterally on level L4 during five days. Based on personalized stimulation protocols, we aimed to evoke dynamic (phase 1) and isotonic (phase 2) motor responses in the bilateral quadriceps muscles. On days 1 and 5, EMG-measurements (root mean square [RMS] values) and clinical muscle force measurements (MRC scoring) were used to measure motor responses and their reproducibility. RESULTS: In all patients, DRG-stimulation evoked significant phase 1 and phase 2 motor responses with an MRC ≥4 for all upper leg muscles (rectus femoris, vastus lateralis, vastus medialis, and biceps femoris) (p < 0.05 and p < 0.01, respectively), leading to a knee extension movement strong enough to facilitate assisted weight bearing. No significant differences in RMS values were observed between days 1 and 5 of the study, indicating that motor responses were reproducible. CONCLUSION: The current paper provides first evidence that bilateral L4 DRG stimulation can evoke reproducible motor responses in the upper leg, sufficient for assisted weight bearing in patients with chronic motor complete SCI. As such, a new target for SCI treatment has surfaced, using existing stimulation devices, making the technique directly clinically accessible.

Percutaneous Nucleoplasty for the Treatment of a Contained Cervical Disk Herniation.

Cervical radiculopathy is characterized by compression of the roots of the nerve. When conservative treatment fails and symptoms persist or increase in severity, surgical treatment is considered. Anterior cervical discectomy with or without fusion is regarded as the standard treatment for cervical disk herniation. Recently, there is an evolving trend in spinal surgery towards less invasive techniques. Nucleoplasty is a minimally invasive technique in which radiofrequency technology is used for percutaneous decompression. During the last years nucleoplasty has been proven to be a safe and effective treatment to alleviate radiculopathy, caused by a contained disk herniation. Nucleoplasty is usually performed on an outpatient basis and is associated with a fast recovery time. This paper will describe the preoperative and postoperative management of cervical nucleoplasty as well as the surgical technique, accompanied by a video.

Anterior cervical discectomy without fusion for a symptomatic cervical disk herniation.

BACKGROUND: Cervical radiculopathy is characterized by dysfunction of the nerve root usually caused by a cervical disk herniation. The most important symptom is pain, radiating from the neck to the arm. When conservative treatment fails, surgical treatment is indicated to relieve symptoms. During the last decades, multiple fusion techniques have been developed, although without clinical evidence for added value of fusion over non-fusion. METHODS: The surgical procedure of anterior cervical discectomy without fusion is performed step by step, leading to removal of the entire intervertebral disk. CONCLUSION: Anterior cervical discectomy without fusion is a safe and effective treatment for cervical disk herniation.

Management of Symptomatic Cervical Disk Herniation: A Survey Among Dutch Neurosurgeons.

STUDY DESIGN: A questionnaire survey. OBJECTIVE: To assess the preferred surgical technique, the optimal timing of surgery, and the expectations of different surgical techniques of neurosurgeons in the Netherlands, regarding patients with cervical disc herniation (CDH). SUMMARY OF BACKGROUND DATA: To treat CDH, multiple surgical techniques are performed. Due to the lack of consensus, the daily routine management may vary. METHODS: All 134 neurosurgeons of the Dutch Association of Neurosurgery were sent a survey, evaluating the operative management as well as the attitude towards different surgical treatments for CDH. RESULTS: Ninety-six (74.4%) of the neurosurgeons treating CDH completed the survey. Anterior cervical discectomy with fusion (ACDF) was the standard procedure for the majority of neurosurgeons (76.3%). ACDF was expected to have the highest effectiveness on arm pain, yet also a higher risk for complications as compared with anterior cervical discectomy (ACD). Approximately, 47.9% of the surgeons regarded a minimal duration of 8 to 12 weeks of radicular arm pain before deciding to perform surgery. Regarding the risk of recurrent CDH, DCF was expected to give the highest risk, whereas ACDF the lowest. CONCLUSION: Despite the lack of solid evidence in favor for ACDF this survey showed that ACDF is the preferred technique to treat cervical radiculopathy. A minimum duration of 8 to 12 weeks of radicular arm pain was considered the optimal timing to perform surgery for CDH by the majority of the neurosurgeons. Whether to fuse or not remains a controversial subject in degenerative spinal surgery. This study emphasizes the need of high-quality evidence on the optimal surgical management of CDH. LEVEL OF EVIDENCE: N/A.
