The treatment of pathologies in the thoracic spine is a challenge. The periodic failure of pedicle screw insertion and anatomical variations make the search for an alternative to pedicle screws in thoracic spine surgery necessary. The interlaminar crossed screws is a well-known and secure method for fusion in cervical spine, and in thoracic spine there used to be insufficient clinical data to support this technique, until now. We demonstrate in an initial series of 10 cases treated with interlaminar fusion in association of other fusion techniques in the thoracic spine with good results. Objective: Intralaminar screws have been shown to be a biomechanical salvage technique in the thoracic spine, especially in long cervicothoracic, thoracic and thoracolumbar fixation. The goals of this article are to demonstrate our initial experience and the range of indications for thoracic crossed intralaminar screws. Methods: In this article we describe our initial series performed at São Teotónio Hospital in Viseu, Portugal, and our results, and also provide a comprehensive review of the recent literature in the use of intralaminar crossed fixation.

Traumatic brain injury is the most common injury during childhood comprising 60% to 90% injuries in children. Pediatric traumatic brain injury has peculiarities as compared to adults, such as less severe injuries and better prognosis. The purpose of this work was to study the pattern of pediatric traumatic brain injury at the General Hospital, Douala, Cameroon. This was a retrospective cross-sectional study, from January 1st, 2008 to December 31st, 2017. Included were all complete medical records of children aged 0 to 15 years old treated for traumatic brain injury, and excluded records of obstetric trauma. Data analysis was done by SPSS software version 18.0. One hundred and three cases of pediatric head injuries were recorded during the study period (frequency 10.43%). The mean age was 7.42 ± 5.028 years, and the sex ratio was 2.67 in favor of boys. Road traffic accidents were the most common etiology (44.7%). 83.5% of the patients were transferred to the emergency department of the Douala General Hospital in second intention and by non-medical transport. The traumatic brain injury was mild in 61.20%. The brain computed tomography scan was performed in 99% of the cases and the most observed lesion was cerebral edema (32.74%). Twenty-eight patients underwent surgical operation. 90.28% of patients have recovered fully, and the global mortality was 3.88%. The prevalence of pediatric traumatic brain injuries at the General Hospital, Douala during the last ten years was 10.43%. Most of the patients recovered fully and the mortality was low.

Introduction: Meningiomas are benign tumors most localized in brain. Intraspinal meningiomas are rare and may have an intra or extradural topography. We report the case of a dorsal psammomatous meningioma revealed by sciatica. Case description: We present a 58-year-old female hospitalized for bilateral painful and disabling L5 sciatica rebellious to medical treatment and physiotherapy. At physical examination, she presented a lumbar spinal syndrome without root deficit. MRI (Magnetic Resonance Imaging) showed a borderline lumbar canal with a paramedian L4-L5 herniated disc. She undergone a first surgery a L4 decompressive laminectomy and there was no postoperative complications. The follow-up was marked by partial pain regression. Three months later, after a fall she presented low back pain and progressive worsening gait troubles. A MRI was realized and shown L3-L4, L4-L5 duct narrowing. A second surgery a L3 and L5 decompressive laminectomy was performed. The postoperative follow up was characterized

Aim: The interest of inflammatory marker increased in the last years, even in preventing clinical outcome after subarachnoid hemorrhage (SAH). Our objective was to study the relationships between C-reactive protein levels and clinical outcome and the development of cerebral vasospasm after aneurismal SAH. Methods: One hundred adult patients with aneurismal SAH were prospectively evaluated. Glasgow Coma Scale (GCS) score, Hunt and Hess grade, Fisher grade, CT scans, digital subtraction angiography studies, transcranial doppler (TCD) and daily neurological examinations were recorded. Serial serum CRP measurements were obtained on daily between admission and 10th days. Glasgow Outcome Scale (GOS) and the modified Rankin Scale (mRS) were used to predict outcome. Results: A progressive increase in the CRP levels from the admission to the 3rd postictal day was observed, followed by a slow decrease until the 9th day. Hemodynamic changes in TCD were associated with higher serum CRP levels. Patients with lower GCS scores presented with increased CRP levels. Patients with higher Hunt and Hess grades on admission developed significantly higher CRP serum levels. Patients with higher admission Fisher grades showed increased levels of CRP. A statistically significant inverse correlation was established in our series between CRP serum levels and GOS and mRS scores on discharge and CRP levels. Conclusion: Increased CRP levels were strongly associated with poor clinical outcome. CRP levels can predict cerebral vasospasm and delayed ischemic deficits with higher statistic significance. There are relationships between hemodynamic chances in TCD and higher CRP levels.

The goal of this work is to report on the efficacy of endoscopic third ventriculostomy (ETV) for non-tumor obstructive hydrocephalus in children aged two years and below. In the period between June 2007 and December 2014, we had performed ETV in 30 patients with hydrocephalus from diverse etiologies. Among them were eight children aged two years or below. Clinical, radiological and outcome data of these children were retrospectively reviewed to assess ETV efficiency in this age group. Eight children (6 boys, 2 girls) with age range from 6 to 24 months (mean 12.5 months, median 15 months) suffering from non-tumor obstructive hydrocephalus underwent ETV as primary treatment. Seven patients (87.5%) were under two years and 3 had less than one year of age at the time of surgery. Macro crania, suture diastasis, scalp vein bulging and sunset gaze were the most common findings on physical examination. Computed tomography scanning was done in all patients but none had magnetic resonance imaging. Hydrocephalus was due to primary (congenital) aqueductal stenosis in all cases and was associated with myelomeningocele in one. ETV was successful in 7 (87.50%) cases but failed in one. Operation time varied from 28 to 35 minutes (mean 31.12 minutes, median 31.5 minutes). No intraoperative complication occurred. The child in whom ETV failed had postoperative CSF leak. No death related to procedure occurred. Hospital stay ranged from 2 to 4 days (mean, 2.87 days, median, 3 days). Follow up range was 5.5 to 86 months (0.46 to 7.16 years);mean, 59.14 months (4.92 years);median, 45.75 months (3.81 years).

The diagnosis and management of cerebral gliomas are challenging. The goal of this study was to evaluate the pattern of cerebral gliomas at the General Hospital Douala, Cameroon. A retrospective study was carried out over a period of 10 years. Non-glial lesions were not included. Data were analyzed with Epi info version 7.***.2.6 (Microsoft, Seattle, USA). 220 cases of brain tumors, comprising 56 gliomas (25.46% of all brain tumors) were managed during the study period. The mean age of the patients was 42.93 ± 16.90 years. 35 cases (62.5%) were males. Patients over 15 years of age represented 91.07% (n = 51) of the cases. The most frequent presenting complaints were headache and vomiting with 52 cases (92.86%) and 47 cases (83.93%) respectively. Brain computed tomography was done for all patients. The most frequent histological type was astrocytoma with 22 cases (39.29%) followed by glioblastoma with 20 cases (35.71%). The most performed surgical technique was partial removal with 33 cases (58.93%), followed by open biopsy with 14 cases (25.00%). Radiotherapy was administered to 54 patients (96.43%). The outcome ranged from full recovery in 8 cases (14.29%), recovery with persisting symptoms, in 15 cases (26.79%) and death in 26 cases (46.43%). Seven patients (12.50%) were lost to view. In this series, cerebral gliomas affected most often adult males. Most of them presented with signs of raised intracranial pressure. The outcome was poor with 46.43% of patients dying before 2 years after diagnosis.

The goal of this work was to report on a series of preoperative endoscopic third ventriculostomy (ETV) performed for obstructive hydrocephalus due to posterior fossa tumors. Eight patients underwent preoperative ETV prior to tumor biopsy or removal for obstructive hydrocephalus related to posterior fossa tumors. All patients underwent surgery in two steps;ETV followed a week later by tumor resection. Clinical, radiological and outcome data were retrospectively reviewed. Eight patients (6 males, 2 females) aged between 8 and 45 years (mean age 24.62 years) suffering from obstructive hydrocephalus due to posterior fossa tumors had ETV prior to tumor removal or biopsy. Five patients were adults while 3 were under 18 years. All patients complained of headaches, seven presented with symptoms of raised intracranial pressure or visual disturbances and four had vomiting or cerebellar disturbance. Computed tomography scan was done in all patients and magnetic resonance imaging in five. Complete tumor removal was achieved in 4 cases and partial removal or biopsy in the remaining 4. ETV was successful in 7 (87.50%) cases but failed in one. Two patients experienced intraoperative transitory bradycardia. Two postoperative complications occurred (one meningitis and one CSF leak). No death related to procedures occurred. The histological diagnosis were as follows: ependymoma (3), medulloblastoma (3), astrocytoma grade II (1) and pineoblastoma (1). Hospital stay ranged from 9 to 21 days (mean, 12.71 days). Follow up range was 4 months to 78.4 months (0.33 to 6.53 years;mean, 46.11 months (3.84 years);median, 41.2 months (3.43 years).
