Introduction  Job satisfaction is a professional aspect that contributes to the achievement of objectives in general and in the health sector; it is a golden standard for having quality care. The satisfaction of nurses is a path toward humanized nursing. This article aims to evaluate the job satisfaction among nurses of the neurosurgery department at Bantane Hospital. Materials and Methods  We conducted a cross-sectional study including 74 nurses at Bantane Hospital in Nagoya Japan in August 2023. Nurses responded to a questionnaire relating to job satisfaction. Univariate analysis was supported by bivariate analyses at the 95% significance level. Results  The survey revealed that nurses aged between 18 and 29 were mostly represented (62.2%). Drip-injection medication was the most preferred activity (15 times) by Bantane nurses. The satisfaction rate was 63.5% and the fact of considering nurses point of view, good interpersonal relationships, and a considerable lunchtime period was statistically significant ( p  < 0.05). Conclusion  Transcendental motivation is a priority in the approach to humanize nursing by considering both monetary and nonmonetary incentives to motivate nurses.

Purpose  There have been numerous advancements in the strategies used for treating mandibular fractures in the present times, while open reduction and internal fixation is still accepted as the most preferred treatment option for such fractures despite numerous drawbacks. The aim of the present prospective, randomized controlled study was to evaluate the clinical outcome including neurosensory deficit and pain score variables in mandibular fractures that were treated using rigid internal fixation with three-dimensional (3D) miniplate internal fixation. Materials and Methods  For the present study, a total of 20 patients of either sex in an age range of 18 to 55 years with simultaneous angle and contralateral body/parasymphysis fractures of the mandible were included, while the clinical outcome was compared in relation to the two groups wherein different treatment options were used including using rigid internal fixation in one as against 3D miniplate internal fixation in the other. Results  Pairwise comparison of pain scores in Group I and Group II patients by the Mann-Whitney U-test at different time zones revealed the results to be statistically significant for all pairs except when the findings were compared between 1 month and 3 months after the procedure in Group II patients. Also, significant recovery was observed in both Group I and II patients during healing when assessed preoperatively to 1 month and then 3 months after the procedure with the results being statistically highly significant in case of the variations observed in relation to the neurosensory deficit observed at different time zones for both Group I and II patients ( p  = 0.0001). Conclusion  Based on the results obtained, it can be concluded that 3D miniplate-led osteosynthesis was found comparable to the osteosynthesis accomplished using reconstruction plates during fixation of unfavorable body/parasymphysis fractures of mandible in study, providing optimal stability, while satisfactorily meeting the biomechanical requirements for occlusal loading, and an early return to normal function.

Study Design  This study was a retrospective study conducted from October 2020 to October 2022 on 106 posttraumatic patients with acute extradural hematomas (EDHs) who were initially planned for conservative treatment. 74 patients had spontaneous EDH regression (EDHR), while 32 patients developed EDH progression (EDHP) and were shifted for surgery. The two groups were statistically compared regarding the different demographic, clinical, and radiographic factors to identify the significant predictors for regression versus progression of acute posttraumatic EDH. Objectives  Conventionally, urgent evacuation is the accepted management for EDH. However, several recent reports have described successful conservative management in selected patients. There are no adequate clues to verify patients who will have spontaneous EDHR from those at risk for EDHP and delayed surgery. The main objective of this study was to identify the significant predictors for possible regression versus progression of acute posttraumatic EDH initially planned for nonsurgical treatment. Materials and Methods  A retrospective study conducted over 2 years, included 106 head trauma patients with acute EDH, who were admitted to our department and were initially planned for conservative treatment. Various demographic, clinical, and radiographic factors were analyzed to verify the significant predictors for spontaneous EDHR (EDHR group) versus EDHP and subsequent surgical evacuation (EDHP group). Results  The mean age was 20.37 ± 12.712 years and the mean Glasgow Coma Scale score (GCS) was 12.83 ± 2.113. Total 69.8% of patients showed spontaneous EDHR, while 30.2% developed EDHP and were shifted for surgical evacuation. Statistical comparison showed that higher GCS ( p  = 0.002), frontal location ( p  = 0.022), and concomitant fissure fracture ( p  =  0.014) were the significant predictors for EDHR, while younger age ( p  = 0.006), persistent nausea/vomiting ( p  = 0.046), early computed tomography (CT) after trauma ( p  = 0.021), temporal location ( p  < 0.001), and coagulopathy ( p  = 0.001) were significantly associated with EDHP. Conclusion  Patients with traumatic EDH fitting the criteria of initial nonsurgical treatment necessitates 48 hours of close observation and serial CT scans at 6, 12, 24, and 48 hours to confirm the regression or early detect the EDHP. Patients with high GCS, frontal hematomas, and associated fissure fracture are at low risk for EDHP. Increased alertness is mandatory for young age and patients with persistent nausea/vomiting, early CT scan, temporal hematomas, or coagulopathy.

Introduction  Predicting the shape of the occluded middle cerebral artery (MCA) from the contralateral MCA might help catheterization in endovascular mechanical thrombectomy (EMT). Materials and Methods  We analyzed magnetic resonance (MR) angiography in 100 consecutive patients who had MR imaging for diseases other than acute ischemic stroke. To assess the symmetricity of MCA, the shape of M1, length of M1, number of M2, number of early branches (EBs), and distance from the top of the internal carotid artery to EB were investigated. Results  The shape of M1 was upward in 42%, horizontal in 47%, and downward in 11%. The M1 shape was the same on both sides in 64%, which exceeded the probability assumed to be left-right independent. The number of M2 trunks and EBs matched left and right in 86 and 55% of patients, respectively; however, these agreement rates were not higher than those with independent left and right sides. No left-right correlation was found between the M1 length and the distance from the internal carotid artery to EB. Conclusion  Based on our data, the symmetry of MCA was observed only in the shape of the M1 segment. This finding could be beneficial for EMT targeting MCA embolisms.

Introduction  Extubation is associated with hemodynamic changes and emergence phenomena leading to cough, sore throat, dysphonia, and dysphagia in the postoperative period. The aim of our study was to compare intracuff 2% alkalinized lignocaine with 1% alkalinized lignocaine and saline in reducing endotracheal tube induced emergence phenomena and haemodynamic changes at extubation in neurosurgical patients. Materials and Methods  In this randomized controlled study, 90 adult patients of either sex, scheduled to undergo neurosurgical procedures were randomly divided into three groups of 30 each to receive either 1% alkalinized lignocaine (AL1), 2% alkalinized lignocaine (AL2), or saline as cuff inflation media. Intracuff pressures and haemodynamic variables were noted intraoperatively and during emergence. The presence of postextubation cough, sore throat, dysphonia, and dysphagia were monitored until 24 hours postoperatively. Data were analyzed using Chi-square test and ANOVA. A p -value of less than 0.05 was considered significant. Results  The intracuff pressures were significantly less with alkalinized lignocaine as compared to saline, after 3 hours of induction. Post extubation, hemodynamic parameters and incidence of coughing and bucking at extubation were significantly less in Groups AL1 ( p  = 0.024) and AL2 ( p  = 0.02) as compared to saline. On assessment of laryngotracheal morbidity, the incidence of coughing was found to be significantly less with 2% alkalinized lignocaine as compared to saline ( p  = 0.021) at 1 hour after extubation. Sore throat was significantly less in Groups AL1 and AL2 as compared with saline at 1 hour ( p  = 0.008, 0.002 respectively) and 8 hours ( p  = 0.01 in both groups), and in Group AL2 versus saline at 24 hours ( p  = 0.044) after extubation. The incidence of dysphonia was significantly less in Groups AL1 and AL2 as compared with saline at 1 hour ( p  = 0.016, p  = 0.002) and 24 hours ( p  = 0.012 in both groups) and in Group AL2 versus saline at 8 hours (p  = 0.03) postoperatively. No significant differences were noted between 1% alkalinized lignocaine and 2% alkalinized lignocaine. Conclusion  Intracuff alkalinized lignocaine 1% and 2% were significantly better than saline in reducing coughing and bucking at extubation, post extubation haemodynamic changes and incidence of postoperative cough, sore throat, and dysphonia.

Objective  In neuroendovascular treatment, there are many opportunities to guide multiple catheters into the intracranial blood vessels. We report the relationship between two microcatheters according to the guiding order with experimental in vitro studies. Materials and Methods  We hypothesize that in a bent blood vessel such as a paraclinoid region of the internal carotid artery, the catheter that was first guided tended to pass through the inside, and the catheter that was guided later tended to pass through the outside. The in vitro verification was performed using a microcatheter and a balloon catheter in a silicone vascular aneurysmal model. Results  As a result, it was found that the two catheters were arranged according to our hypothesis. This finding was also observed during the actual operation of balloon-assisted coil embolization. Conclusion  The positional relationship between the two catheters according to the navigation order is very important, in particular during balloon-assisted coiling and stent-assisted coiling via a jailed microcatheter.

Although many authors have recommended the retractorless technique to avoid retractor-induced brain injury, others usually use brain retractors with a meticulous technique to facilitate the surgery, especially for sylvian fissure dissection. The intrasylvian retraction technique was described for sylvian fissure opening, but no clinical evidence was found. We evaluate the efficacy and safety of this technique for the distal transsylvian approach. We reviewed the video records of clinical cases where the distal transsylvian approach was performed using the intrasylvian retraction technique for aneurysm treatment and middle cerebral artery (MCA) bypass between September 2018 and August 2022. Operative techniques are described. The efficacy and safety of the technique were assessed by full exposure of the sylvian fissure and new postoperative perisylvian hematoma, respectively. One hundred twenty-five cases were included and had an average age of 53.5 (range 16-85) years. Women comprised 73.6%. Aneurysm surgery, pure MCA revascularization, and aneurysm surgery with MCA revascularization were 106 (84.8%), 12 (9.6%), and 7 cases (5.6%), respectively. The most common aneurysm location was the internal carotid artery-posterior communicating artery junction in 37 cases (34.9%), followed by the anterior communicating artery in 27 (25.5%). Full exposure of the Sylvian fissure was achieved in all cases. No perisylvian hematoma was detected by immediate postoperative computed tomography in any patient. Using an appropriate technique for brain retractor application, sylvian fissure dissection was safely performed. The intrasylvian retraction technique effectively facilitated sylvian fissure dissection and provided wide exposure for the distal transsylvian approach.

Background  Untreated cerebrospinal fluid (CSF) rhinorrhea and otorrhea can lead to adverse complications like meningitis and hence should not be overlooked. Acetazolamide reduces CSF production by 48%. The actual role of acetazolamide in the amelioration of traumatic CSF rhinorrhea and otorrhea is not clear as, till date, very few formal studies have been conducted. Aim of the study was to determine the role of acetazolamide in traumatic cerebrospinal fluid rhinorrhea and otorrhea. Materials and Methods  A randomized controlled trial was conducted among 134 patients with head injuries presenting to the neurosurgery department of a tertiary care center in North India, with complaints of CSF rhinorrhea and otorrhea within 72 hours of traumatic injury. One-hundred thirty-four patients were randomized into intervention and control group. Comparative analysis was not possible in 58 patients as in due course they were either operated for head injury or lumbar drain was put due to excessive CSF leak; hence, forth comparative analysis was done in 76 patients. Out of these 76 patients, 44 patients belonged to the intervention group (Acetazolamide given) and 32 belong to the control group (Acetazolamide not given). The day of the stoppage of CSF Leak was the main endpoint of this study. Result  Majority of the patients were in the age group of 21 to 30 years and were predominantly males. Road traffic accident was observed in 84 (75%) patients. There was no statistically significant difference noted in the mean number of days of CSF leak whether acetazolamide was given or not ( p  = 0.344). The complication associated with CSF leak was meningitis. The percentage of patients developing meningitis was more after lumber drain insertion. Conclusion  In our study, there was no advantage of adding acetazolamide to the conservative management of traumatic CSF leak. Therefore, the practice of routinely giving acetazolamide should be reconsidered.

Herein, we describe a 55-year-old female patient with a functional movement disorder (FMD) who presented with normal pressure hydrocephalus (NPH)-like clinic. The neuroimaging data and positive response to the tap test initially suggested NPH. However, a detailed investigation of the clinic features yielded a final diagnosis of FMD. Via the presentation of this patient, we expand the phenomenology of FMD. To our knowledge, this is the first presentation of a patient with FMD mimicking NPH. Therefore, we think this rare illustration is interesting and may provide valuable perspectives for clinical practice.
