Facial herpes zoster infection precipitated by surgical manipulation of the trigeminal nerve during exploration of the posterior fossa: a case report

<p>Abstract</p> <p>Introduction</p> <p>We present a case of herpes zoster infection (shingles) precipitated by surgical manipulation of the trigeminal nerve root during an attempted microvascular decompression procedure. The pathogenesis of this phenomenon, as well as the importance and role of prophylactic acyclovir in its management, are discussed.</p> <p>Case presentation</p> <p>A 54-year-old Caucasian man with a classical long-standing left-sided V2 and V3 division primary trigeminal neuralgia refractory to medical management, underwent posterior fossa exploration for microvascular decompression via a standard retromastoid craniectomy. The patient had immediate and complete relief from pain. Three days after the operation, he developed severely painful vesicles with V2 and V3 dermatomal distribution. Rather than the classical paroxysmal, lancinating type of trigeminal neuralgia, the pain experienced by the patient was of a constant burning nature. A clinical diagnosis of herpes zoster (shingles) was made after smear confirmation from microbiological testing. The patient was commenced on antiviral treatment with acyclovir. His vesicular rash and pain gradually subsided over the next two weeks. He remains asymptomatic one year later.</p> <p>Conclusions</p> <p>Postoperative shingles precipitated by trigeminal nerve manipulation during surgery for trigeminal neuralgia can be a distressing and demoralizing experience for the patient. A careful preoperative history, early recognition, and prompt antiviral therapy is necessary.</p

Outcomes of endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS) in the treatment of paediatric hydrocephalus: Systematic review and meta-analysis

Purpose To evaluate the outcomes of endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS) in the treatment of paediatric hydrocephalus. Methods We searched PubMed, MEDLINE, and Cochrane Central Register of Controlled Trials databases for articles published from 2000 to May 2023 (last search date May 6, 2023). Keywords searched included “endoscopic third ventriculostomy”, “ventriculoperitoneal shunting”, “paediatric population”, and “outcomes”. Using random-effects models, we compared success rates and complications of ETV and VPS. The primary outcome was ETV vs.VPS success rates, and the secondary outcome was post-treatment complications. Included studies reported on treatment success and complication rates. Results Out of 126 articles, 8 RCTs and 1 prospective study were included. Six studies reported primary outcome data (806 patients identified: 464 in ETV group, 342 in VPS group). Combined success rates were 81.8% (n = 283/346) for ETV and 86.7% (n = 182/210) for VPS (median follow-up 41 months). There was no difference in success rates between ETV and VPS groups (risk ratio 0.84, 95% confidence interval 0.80–0.90, I2 = 0%, p = 0.93). Combined complication rates were 4.6% (n = 16/346) in the ETV group and 27.1% (n = 57/210) in the VPS group. ETV had a lower rate of postoperative complications (risk ratio 0.76, 95% confidence interval 0.42–1.38, I2 = 53%, p = 0.04). Conclusions Both ETV and VPS are viable surgical options for the management of paediatric hydrocephalus with similar success rates when used as first-line treatment. However, our study concluded that VPS results in a higher complication rate. Registration This systematic review and meta-analysis was formally registered in the PROSPERO International database under the registration number CRD42023452907 on the 29th of August 2023

Breaking boundaries in neurosurgery through art and technology: A historical perspective

Introduction: Since the past, art has been used as a tool to elaborate anatomical knowledge and guide surgeons to perform surgeries. Through the eras, art has taken role by conveying the knowledge to people in forms of illustrations and models, including neuroanatomy knowledge for neurosurgical purposes. With the advancement of technology, neurosurgical trainings and care evolve more than before. Research question: How do art and technology play role in tbe education and development of neurosurgery? Materials and methods: A literature search was conducted to find the role of art and technology in forms of illustrations, models, or others in neurosurgery. Results: Illustration was known as one of the tools to understand it in the past. Now, in the modern era, neurosurgical learning, training, and teaching process have integrated both art and technology throughout the process. Not only as two-dimenional drawings, art and technology have gone as far as being developed into three-dimensional models and create specific models for surgical plannings and simulations. Artificial intelligence, virtual reality, and augmented reality have also been used to achieve accurate and efficient learning process and neurosurgical care. Discussion and conclusion: Art does take significant role in the progression of neurosurgery. When combined with technology, art give greater utility and impact through the learning, teaching process, and delivery of care in neurosurgical world

Pseudotumor cerebri following traumatic brain injury in a 29-year-old man

We describe a case of pseudotumor cerebri in a young man developing 4 years post-traumatic brain injury (TBI). A 29-year-old man was admitted after sustaining a fall with headache, and no clinical deficits were noted on examination. CT brain demonstrated an extradural hematoma. This was successfully evacuated after his symptomatic worsening. Following this, he developed bone flap infection and had the infected bone flap removed. He developed chronic mild-to-moderate headache following these procedures, which failed to respond to medical treatment. Pseudotumor cerebri was diagnosed. A lumboperitoneal (LP) shunt, ventriculo-peritoneal (VP) shunt, and bitemporal craniectomy were performed as a part of management at different stages. Post-TBI patients may present with chronic headache and in such circumstances, a possibility of pseudotumor cerebri must be considered. Investigations should include neuroimaging in the form of MRI/MRV and fundoscopy to look for papilledema. Management in the form of CSF flow diversion techniques (VP and LP shunt) with medical management results in good clinical outcome

Fertility Preservation Techniques in Neuro-Oncology Patients: Protocol for a Systematic Review

BackgroundAdvancements in cancer treatments have successfully improved central nervous system (CNS) cancer survivorship and overall quality of life. As a result, the awareness of the importance of fertility preservation techniques is increasing. Currently, a range of established techniques, such as oocyte cryopreservation and sperm cryopreservation, are available. However, oncologists may be hesitant to refer patients to a reproductive specialist. ObjectiveThe primary aim of the proposed systematic review is to assess the best evidence for fertility preservation techniques used in patients with CNS cancers. It also aims to evaluate outcomes related to their success and complications. MethodsThis protocol was produced in adherence with the PRISMA-P (Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols). Electronic databases will be systematically searched to identify studies that meet our eligibility criteria. Studies will be included if they report at least one type of fertility preserving or sparing technique in male patients of any age and female patients aged <35 years. Animal studies, non-English studies, editorials, and guidelines will be excluded from the review. From the included studies, data will be extracted and synthesized by using a narrative approach and summarized in tables. The primary outcome will be the number of patients successfully undergoing a fertility preservation technique. The secondary outcomes will include the number of retrieved oocytes, the number of oocytes or embryos vitrified for cryopreservation, clinical pregnancy, and live birth. The quality of the included studies will be assessed by using the National Heart, Lung, and Blood Institute risk-of-bias tool for any type of study. ResultsThe systematic review is expected to be completed by the end of 2023, and results will be published in a peer-reviewed journal and on PROSPERO. ConclusionsThe proposed systematic review will summarize the fertility preservation techniques available for patients with CNS cancers. Given the improvement in cancer survivorship, it is becoming increasingly important to educate patients about fertility preservation techniques. There are likely to be several limitations to this systematic review. Current literature is likely to be of low quality due to insufficient numbers, and there may be difficulty in accessing data sets. However, it is our hope that the results from the systematic review provide an evidence base to help inform the referral of patients with CNS cancers for fertility preservation treatments.

Promoting padawans: a survey examining the state of mentorship in neurosurgical training in the United Kingdom

Mentorship has long since been acknowledged as an integral part of Neurosurgical training. The authors sought to evaluate the state of mentorship in Neurosurgical training in the United Kingdom (UK). A 28-point questionnaire was sent to all neurosurgical trainees in the UK and Ireland via the British Neurosurgical Trainee’s Association (BNTA), comprising 180 trainees. There were 75 responses (180 trainees on the mailing list, 42% response rate). Despite all respondents reporting it to be at least somewhat important to have a mentor, 16% felt they had no mentors. The mean number of mentors was 2.91 with 72% of respondents having more than 1 mentor. In terms of the content of mentorship relationships, 63% were comfortable discussing career related topics with their mentor to a high or very high degree but only 29% felt comfortable discussing their general wellbeing. With regards to allocated educational supervisors, 43% thought this person to be a ‘low’ or ‘very low’ source of mentorship. The three most important traits of the ideal mentor as reported by respondents were: someone chosen by them (48%), working in the same hospital (44%) and having received formal mentorship training (36%). The current perception of mentorship in Neurosurgery from the surveyed trainees is mixed. A healthy majority of trainees benefit from mentorship of some kind, whilst a significant minority feel underserved. The surveyed trainees feel mentorship is slanted more towards clinical and professional aspects of development than it is towards personal ones. Suggestions for future insight would be an evaluation of senior registrar and consultant sentiments towards mentorship, whilst exploration into more flexible models for establishing mentoring relationships may help to address the heavy importance of trainee choice which is voiced by this survey’s results.</p
