Background: Treatment of brain abscess is still a subject of controversy. The main treatment is surgical, although medical therapy alone can be used for selected cases. The treatment of choice is aspiration, which may be performed with the aid of an endoscope or by freehand technique, with or without stereotactic or intraoperative ultrasound guidance. Excision is valuable in some cases. We are reporting our results of endoscopic approach in 12 patients. Methods: This study included 12 patients of brain abscesses treated between January 2015 and January 2018. All the cases except those with small abscesses (<3.0 cm in diameter) were included in the study. Rigid endoscope was used. Follow-up CT scan was done in all cases within 7 and 30 days after surgery. Follow-up periods ranged between 3 and 6 months. Results: There were 11 patients with a history of chronic otitis media and one patient who suffered from congenital cyanotic heart disease. Glasgow Coma Score (GCS) was 5 in one patient, 13 in two cases, and 14–15 in 9 cases. There were one cerebellar, six temporal, and five frontal abscesses. All the patients recovered completely except one who died (GCS 5). There was no procedure-related complication. Hospital stay ranged from 14 to 45 days with an average of 28 days. The endoscopy aided visualization of multiloculations and septation in eight patients which allowed the opening of the septations and complete evacuation. Conclusion: Endoscopic aspiration is safe, easy, and represents an effective way of treatment of brain abscess through proper visualization. It can be used for ensuring the complete aspiration of contents, control of any bleeding point, and also for multiloculated abscess to identify and open the septations which may not be possible in stereotactic or any other guided aspirations.

Background: The incidence of subdural hematoma (SDH) in chronic maintenance hemodialysis (CMH) patients may change over time, along with the evolving characteristics of the underlying populations. Methods: We conducted a retrospective, single-center study at Cairo University hospitals, assessing the incidence, associated risk factors, and outcomes of nontraumatic SDH in CMH patients between January 2006 and January 2019. Results: Out of 1217 CMH patients, nontraumatic SDH was diagnosed in 41 (3.37%) during the study, increasing with the enrollees' age but stable over the observation period and translating into an annual incidence rate of 28 per 1000 patients per year. SDH patients were likely to use central venous catheters, reported pruritis and history of bone fractures, and had higher phosphorus, parathyroid hormone, and alkaline phosphatase values (p < 0.001); however, there was no association with atrial fibrillation or use of anticoagulants. In the SDH cohort (n ¼ 41), six patients did not need surgical intervention and 13 patients died before becoming surgically fit for intervention; mortality correlated with ischemic heart disease (p ¼ 0.033) and the presence of atrial fibrillation or chronic anticoagulation with warfarin (p < 0.0001 for both), among others. Twenty-two patients received surgical operations and of these 2 died postoperatively; overall patient mortality was 12/41 (29.27%) at 30 days and 15/41 (36.59%) at 1 year. Conclusion:Our study demonstrated a striking enrichment for underlying comorbidities in those patients developing SDH and a high risk of immediate mortality. The benefit of chronic anticoagulation therapy should be carefully weighed against the risk of CNS bleed in MHD patients.

BACKGROUND: There is a lack of evidence of whether degenerative cervical myelopathy (DCM) is best treated through cervical laminoplasty (CLP) or cervical laminectomy with lateral mass fusion due to the lack of prospective randomized studies that are well designed. We conducted the largest prospective randomized trial to date to determine the comparative effectiveness and safety of both approaches. METHODS: In this prospective, randomized trial, we randomly assigned patients who had symptoms or signs of DCM to undergo either cervical laminectomy and lateral mass fixation (CLF) or CLP. The primary outcome measures were the change in the Visual Analog Scale (VAS), neck disability index, modified Japanese Orthopedic Association (mJOA) score, and Nurick’s myelopathy grading 1 year after surgery. The secondary outcome measures were the intraoperative, post-operative complications, hospital stay, C2-7 Cobb’s angle, and Odom’s criteria. The follow-up period was at least 1 year. RESULTS: A total of 30 patients (mean age, 54.5 ± 5.5 years, 70% of men) underwent prospective randomization. There was a significantly greater improvement in neck pain (VAS) in the CLF group at 1 year (p < 0.05). The improvement in the mJOA and Nurick’s myelopathy grading showed insignificant improvement between both groups. Furthermore, there was no significant difference in the patient’s post-operative satisfaction (Odom’s criteria). The mean operative time was significantly longer in the CLF group (p < 0.001), with no significant difference in the post-operative complications, however, there was a higher rate of C5 palsy, dural tear and infection in the CLF, and a higher rate of instrumentation failure in the CLP. The mean hospital stay was significantly longer in the posterior group (p < 0.05). Finally, there was a significant better improvement in the C2-7 Cobb’s angle at 1 year in the CLF group (p < 0.05). CONCLUSION: Among patients with multilevel DCM, the CLF approach was significantly better regarding the post-operative pain and Cobb’s angle while the CLP was significantly better in terms of shorter hospital stay and operative time.

Background: Chronic subdural hematoma (CSDH) is a common problem encountered in daily practice in neurosurgery departments worldwide. It is defined as abnormal collection of blood or blood product in the subdural space with an indolent course. The recurrence rate of CSDH ranges from 2% to 37%. Aim of Study:We tried to find if there a significance of the number of burr-holes in surgical evacuation of CSDH in relation to the rate of recurrence or the rate of complications. Patients and Methods:This a prospective interventional study conducted over 32 patients with chronic subdural hematoma treated between January 2018 and January 2021. The patients were divided into 2 groups, 16 patients were operated by single burr-hole craniostomy (SBHC), and the other 16 patients were operated by double burr-hole craniostomy (DBHC). Recurrence was considered if there is need for re-evacuation of the hematoma surgically.Results: Group A: This group included 16 patients operated by 2 burr holes. The only reported surgical complication in this group was superficial wound infection in 2 cases (12.5%). Recurrence was reported in one case only (6.3%). Group B: This group included 16 patients operated by single burr hole. Regarding the surgical complications: Superficial wound infection was reported in one case (6.3%) and incomplete evacuation in one case (6.3%). Recurrence was reported in 2 cases (12.5%). Conclusion:In our study, we found that the patients with CSDH operated upon by SBHC had higher rate of recurrence than those operated by DBHC, although it was not statistically significant (p>0.05). There is no statistical significance regarding the rate of complication between both techniques. We conclude that surgical management of CSDH with SBHC is safe and efficient as DBHC.
