Salmonella intracranial infection is infrequently encountered in clinical practice. However, with prompt intervention and appropriate antimicrobial therapy, the outcome is usually favourable. A 56-year-old gentleman who worked as an organic fertilizer production supervisor underwent tumour resection for meningioma located at the left frontal temporoparietal region. The surgical procedure went smoothly, and he has prescribed dexamethasone thereafter. He was discharged well. However, a few days after that he developed a fever associated with pus discharged from the surgical wound. A computed tomography (CT) scan of the brain was performed and it revealed an abscess located at the left frontal temporoparietal subdural and subgaleal regions with adjacent cerebritis. Another craniotomy was done to drain the abscess. The bacterial culture of the pus specimen grew Salmonella Enteritidis. The bacterium was susceptible to ciprofloxacin, ceftriaxone, and amoxicillin-clavulanic acid. Clinical improvement was evident after surgical intervention with an additional 6 weeks of ceftriaxone therapy.

Fulltext Risk factors for neurosurgical site infections after a neurosurgical procedure: a prospective observational study at Hospital Kuala Lumpur

Buang SS, Haspani MS

Med J Malaysia, 2012 Aug;67(4):393-8.
PMID: 23082448

Surgical site infection (SSI) after craniotomy even though rare, poses a real risk of surgery and represents a substantial burden of disease for both patients and healthcare services in terms of morbidity, mortality and economic cost. The knowledge of risk factor for surgical site infection after craniotomy will allow the authority to implement specific preventive measures to reduce the infection rate. Therefore, the objectives of this study are to determine the incidence and the risk factors of surgical site infection after craniotomy.

Does Putting Back Hyperostotic Bone Flap in Meningioma Surgery Cause Tumor Recurrence? An Observational Prospective Study

Lau BL, Che Othman MI, Fathil MFMD, Liew DNS, Lim SS, Bujang MA, et al.

BACKGROUND: Replacing the skull defect with synthetic materials for hyperostotic bone secondary to meningioma is recommended owing to the possibility of tumor invasion. In our institution, neurosurgeons have been putting back the refashioned hyperostotic bone flap after meningioma excision because of budget constraints. The aim of this study was to review the long-term meningioma recurrence rate in these patients.
METHODS: This was a nonrandomized, prospective observational study conducted from September 2011 to January 2015 on patients with intracranial convexity and parasagittal meningiomas. Preoperative computed tomography brain scans were obtained in all patients to confirm bony hyperostosis. Intraoperatively, part of the hyperostotic bone was sent for histopathologic examination. The rest of the bone flap was refashioned by drilling off the hyperostotic part. The bone flap was put back over the craniotomy site after soaking in distilled water. All patients were followed up for tumor recurrence.
RESULTS: The study included 34 patients with convexity or parasagittal meningioma World Health Organization grade I-II who underwent Simpson grade Ia and IIa excision. Median follow-up was 63.5 months (mean 64.9 ± 9.4 months). The hyperostotic bone flap showed presence of tumor in 35% of patients. There were 2 patients with parasagittal meningiomas after Simpson grade IIa resections who developed tumor recurrences.
CONCLUSIONS: Our study found that meningioma recurrence was unlikely when autologous cranioplasty was done with refashioned hyperostotic bone. This could be done in the same setting with meningioma excision. There was no recurrence in convexity meningiomas at mean 5-year follow-up.

Comparison of the effect of scalp block analgesia bupivacaine 0.25% and clonidine 2 μg/kg with bupivacaine 0.25% and dexamethasone 8 mg on cortisol levels and Numeric Rating Scale in craniotomy tumour

INTRODUCTION: Craniotomy tumour is brain surgery that can induce a stress response. The stress response can be measured using haemodynamic parameters and plasma cortisol concentration. The stress response that occurs can affect an increase in sympathetic response, such as blood pressure and heart rate, which can lead to an increase in intracranial pressure. Scalp block can reduce the stress response to surgery and post-operative craniotomy tumour pain. The local anaesthetic drug bupivacaine 0.25% is effective in reducing post-operative pain and stress in the form of reducing plasma cortisol levels. The adjuvant addition of clonidine 2 μg/kg or dexamethasone may be beneficial.
MATERIALS AND METHODS: A randomised control clinical trial was conducted at the Central Surgery Installation and Hasan Sadikin General Hospital Bandung and Dr. Mohammad Husein Hospital Palembang from December 2022 to June 2023. A total of 40 participants were divided into two groups using block randomisation. Group I receives bupivacaine 0.25% and clonidine 2 μg/kg, and group II receives bupivacaine 0.25% and dexamethasone 8 mg. The plasma cortisol levels of the patient will be assessed at (T0, T1 and T2). All the patient were intubated under general anesthaesia and received the drug for scalp block based on the group being randomised. Haemodynamic monitoring was carried out.
RESULTS: There was a significant difference in administering bupivacaine 0.25% and clonidine 2μg/kg compared to administering bupivacaine 0.25% and dexamethasone 8 mg/kg as analgesia for scalp block in tumour craniotomy patients on cortisol levels at 12 hours post-operatively (T1) (p=0.048) and 24 hours post-surgery (T2) (p=0.027), while post-intubation cortisol levels (T0) found no significant difference (p=0.756). There is a significant difference in Numeric Rating Scale (NRS) at post-intubation (T0) (p=0.003), 12 hours post-operatively (T1) (p=0.002) and 24 hours post-surgery (T2) (p=0.004), There were no postprocedure scalp block side effects in both groups.
CONCLUSION: The study found that scalp block with 0.25% bupivacaine and 2μg/kg clonidine is more effective in reducing NRS scores and cortisol levels compared bupivacaine 0.25% and dexamethasone 8mg in tumour craniotomy patients.

Fulltext The craniotomy box: an innovative method of containing hazardous aerosols generated during skull saw use in autopsy on a COVID-19 body

During a disease pandemic, there is still a requirement to perform postmortem examinations within the context of legal considerations. The management of the dead from COVID-19 should not impede the medicolegal investigation of the death where required by the authorities and legislation but additional health and safety precautions should be adopted for the necessary postmortem procedures. The authors have therefore used the craniotomy box in an innovative way to enable a safe alternative for skull and brain removal procedures on suspected or confirmed COVID-19 bodies. The craniotomy box technique was tested on a confirmed COVID-19 positive body where a full postmortem examination was performed by a team of highly trained personnel in a negative pressure Biosafety Level 3 (BSL-3) autopsy suite in the National Institute of Forensic Medicine (IPFN) Malaysia. This craniotomy box is a custom-made transparent plastic box with five walls but without a floor. Two circular holes were made in one wall for the placement of arms in order to perform the skull opening procedure. A swab to detect the presence of the SARS-CoV-2 virus was taken from the interior surface of the craniotomy box after the procedure. The result from the test using real-time reverse transcriptase polymerase chain reaction (rRT-PCR) proved that an additional barrier provided respiratory protection by containing the aerosols generated from the skull opening procedure. This innovation ensures procedures performed inside this craniotomy box are safe for postmortem personnel performing high risk autopsies during pandemics.
