Abstract: Hydrocephalus had been managed by ventriculoperitoneal shunt (VPS) or endoscopic third ventriculostomy (ETV) since several years. But these two different technics had some complications that must be managed promptly to avoid eventual fatal evolution. Chronic subdural hematomas after ETV is among these complications and is a very rarely situation observed in our department. This rare event associated with malaria in a child is considered to have a high mortality. Here we report a rare case of bilateral chronic subdural hematoma occurring in a 4-month-old boy after ETV and we discuss the likely pathogenesis and the difficulties of management.

Abstract: Grisel’s syndrome is a rare complication that is characterized by non-traumatic atlantoaxial subluxation. It is most commonly seen in children after an upper respiratory tract infection or neck surgery, such as an adenoidectomy, tonsillectomy and mastoidectomy. Grisel’s Syndrome is characterized by torticollis and a limited range of motion of the neck with pain. Here the authors report a case of a Malian 5-year-old girl with Grisel’s syndrome following tonsillectomy. The patient’s complaints were fully resolved after 2 weeks of conservative treatment.

Abstract: Introduction: Gold panning is the research and artisanal exploitation of gold in the auriferous areas (rivers or others). Traumatisms arising from these activities are due to severe spinal cord injury and generally affect young people in full activity. They constitute a real social handicap in Mali and even in Africa. The aim of our study is to share our expertise in the management of these vertebro-medullary traumasin these miners who currently escape to all controls in Mali. Material and Methods: From 2013 to 2016, 76 Traumatic Spine Cord Injuries (TSCI) were treated in the department of Neurosurgery of “Hôpital du Mali”. There were 73 males (96.05%) versus 03 Females (3.95%), aged between 21 - 43 years old. Results: All of our patients were admitted with deficit differing from paraparesis to tetraplegia. According to Frankel scale, we found 59 patients with complete deficits (A grade, 77.63%), and incomplete deficits in 17 cases (12 grade B, 04 grade C, 01 grade D). The X-ray standard radiographies were done in 24 cases (31.58%) from which 02 patients had been operated with these data. CT scan centered on the injured spinal segment was performed in 74 cases (97.37%). The lumbar spine was affected in 39 cases, followed by thoracolumbar junction in 19 cases and thoracic spine in 16 cases. The cervical spine was only interested in two cases. Fractures dislocations are the most frequently lesions

Abstract: Objective: This study aims to analyze clinical, paraclinical and therapeutic aspects of sinusitis complications in the Otorhinolaryngology department at the teaching hospital of Gabriel Toure in Bamako. Materials and methods: This descriptive and longitudinal study was conducted on 12 months from March 2012 to February 2013 in 9 cases of sinusitis complications in the department of Otorhinolaryngology at the University Hospital Gabriel Toure in Bamako. Results: The average age of patients was 22.7 years; a median of 19 years within 6 men and 3 women with almost 12.9 days of care seeking duration. The factors of risky were the use of nonsteroid anti-inflammatory drugs NSAID (4 cases), maxillofacial trauma (1 case) and HIV (1 case). Facial pain was the major symptom, such as frontal oedema, rhinorrhea with pus shedding and nasal obstruction. Computer tomography was used for complications specification. Frontal sinusitis was the most encountered with subperiosteal abscess (44.4%). Streptococcus pneumoniae was identified in 3 cases. Medical treatment associated to surgery was conducted on 7 patients. Two cases of death have been registered. Conclusion: The complicated sinusitis is an emergency and dangerous disease requiring specific care by a multidisciplinary staff. Much of complications are commonly encountered despite the antibiotic era.

Abstract: Pleomorphic xanthoastrocytoma (PXA) generally occurs in children and young adults and is classified as a low-grade astrocytic tumor with a potential favorable prognosis. But these data must be interpreted with much caution, because of some rapid progression or malignant transformation during the postoperative follow-up. We report herein a rare case of a cerebellar PXA manifested as a benign lesion at first time in a 39 year-old woman, but with malignant transformation two years later. In this paper, we discuss the clinical signs, radiological findings and the therapeutic data on the subject according to literature review.

Abstract: Intracranial arachnoid cysts (IAC) are benign lesions containing cerebrospinal fluid (CSF). Most of them are clinically silent and remain static in size. However some may present with mild and slow progressive symptoms caused by the cyst. The authors present the case of 54-year-old woman who presented with acute symptoms of severe headache, vomiting, and gait disturbance of 2 day’s duration. She had no history of head trauma. On admission, neurological examination revealed that the patient had a Glasgow Coma Scale score of 15, and a left side hemiplegia. A CT scan revealed a hypodense fluid collection in the right frontoparietal region that mimicked an arachnoid cyst. The symptoms were improved after an emergency marsupialisation via craniotomy.

Abstract: Background: Spinal schwannomas are common tumors of spinal neoplasm and account for about 25% of intradural spinal cord tumors in adults. They are generally benign and slow-growing. Advanced in radiologic and surgical techniques have brought about better surgical results. The goal of surgical treatment must be total resection if possible. In this report, the authors present the incidence, clinical presentation, localization, and results of surgically treated spinal schwannomas. The results of a literature review are also presented. Methods: Eleven consecutive patients with histologically confirmed spinal schwannomas were treated from January 2013 to December 2016 in the neurosurgical department of Gabriel Touré Hospital, Bamako, Mali. Neuroradiological diagnosis was made, CT scan in 7 patients, and MRI in 4 patients. All patients were operated on via the posterior approach. All cases were surgically excised, and they were confirmed to be schwannomas by pathologists. The patients were followed for 6 to 38 months (mean 28 months). Functional outcome was assessed using the motor grade and sensory change. Results: There were 11 patients with 7 (63.6%) males and 4 (36.4%) females. The mean age was 40.3 years (range 23 - 62 years). The most common symptom at the time of diagnosis was radicular pain in 9 (81.8%) patients followed by motor weakness in 8 (72.7%) patients. The most frequent site of spinal schwannomas was the thoracic region in 5 (45.5%) patients. During surgery, Gross-total resec-tion was achieved in 8 patients (72.7%) and subtotal removal in 3 (27.3%) patients. Histological findings were benign schwannoma in all cases. Postoperative complications developed in two patients, including one with cerebrospinal fluid leakage and other one with wound infection. In the short-term follow-up period, most of the patients (90.9%) appeared to be improved in comparison with their preoperative neurological status. There was no operative mortality. Conclusion: In this study, the clinical manifestations and surgical results of 11 cases of spinal schwannoma have been reviewed. Early diagnosis and appropriate treatment are essential for good outcome.

Abstract: Background: Encephaloceles are congenital neural tube defects characterized by the protrusion of meninges and/or brain tissue from a defect in the skull. The incidence of the disease is about 0.8 - 5.6/10,000 live births. They are classified based on the location and type of skull defect as occipital encephalocele, encephalocele of the cranial vault, frontoethmoidal encephalocele, and basal encephaloceles. Surgical reduction being the first line treatment and resection of herniated structures may be necessary when the encephalocele is large. In the present study, the authors present their experience in treating 17 patients with encephaloceles. Methods: This study is a retrospective analysis of 17 patients from January 2013 to December 2016 in Gabriel Touré Hospital, Bamako, Mali. A history was obtained from the family at presentation. Medical information before and during the pregnancy was compiled. All patients underwent CT scan as a routine preoperative imaging study, to evaluate the encephalocele and to plan the surgical procedure. The following data were recorded for analysis: age, sex, location of encephalocele, neurological status, operative method, postoperative complications and surgical results. Results: There were 10 (58.8%) female and 7 (41.2%) male patients. The patients ranged in age from 3 days to 36 months. The most common site of encephalocele sac was the occipital region in 14 (82.4%) cases followed by the frontal region in 2 (11.8%) cases and the vertex in 1 (5.9%) case. The sac size was less than 3 cm in 5 (17.6%) cases, 3 - 5 cm in 8 (47.1%) cases and more than 5 cm in 4 (23.5%) cases. Three (17.6%) children presented with CSF leakage. Hydrocephalus was present in the preoperative period in 6 (35.3%) cases; all of them required VP shunt procedure. None of the cases had a preoperative neurologic deficit. Surgical excision was performed in all cases. In the postoperative period, meningitis developed in 2 cases (11.8%), wound infection in 1 case (5.9%) and seizure in 1 case (5.9%). Three patients (17.6%) died during postoperative follow-up. Postoperative hydrocephalus occurred in 1 (5.88%) patient requiring a VP shunt. Conclusion: Encephaloceles are commonly seen in the practice of neurosurgery in the world as well as in Mali. In this study, the clinical manifestations and surgical results of 17 cases have been reviewed. We recommend early repair and excision of encephaloceles to avoid rupture or skin excoriation.

Abstract:  Infratentorial subdural empyemas are rare. It is an important neurological infection requiring immediate neurosurgical treatment. The nonsurgical treatment of subdural empyema has been reported sporadically. In this paper the authors report the nonsurgical treatment of a case of infratentorial subdural empyema. The patient with left recurrent otitis was hospitalized with symptoms of headache and fever of 3 weeks duration. Examination revealed that the patient had Glasgow Coma Scale score of 15, fever, mild cerebellar signs, no focal deficit, and abundant suppuration from the left ear. A contrast-enhanced CT scan showed an infratentorial supracerebellar hypodense fluid collection with the peripheral rim enhancement to the left of the midline that mimicked a subdural empyema. Routine hematological investigation revealed polymorphic leukocytosis and elevated erythrocyte sedimentation rate. After the left mastoidectomy and antibiotic treatment, the patient recovered with complete resolution of the subdural empyema on CT scan.
Isoperimetric inequality for an interior free boundary problem with p-laplacian operator
drissa Ly,Diaraf Seck
Electronic Journal of Differential Equations , 2004,
Abstract: By considering the p-Laplacian operator, we establish an existence and regularity result for a shape optimization problem. From a monotony result, we show the existence of a solution to the interior problem with a free surface for a family of Bernoulli constants. We also give an optimal estimation for the upper bound of the Bernoulli constant.
