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: 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: Introduction: Myasthenia is a rare and disabling autoimmune disease. Few studies were devoted to this pathology. We report a clinical case of myasthenia in the Department of Internal Medicine at the Point G University Teaching Hospital. Observation: This is a 41-year-old patient of Malian origin, a trader with a history of hemorrhoidectomy in 2011 and familial hypertension, was admitted on August 19, 2014, for muscle weakness, dysphonia, and dysphagia. The disease started 1 year before admission at the department with progressive muscle weakness of the upper limbs aggravated by repetitive movements and spreading to the head “drooping head” and inferior limbs, associated with general fatigue, dysphonia and selective dysphagia for solid foods. The diagnosis of myasthenia was maintained based on the clinical signs such as ptosis, bilateral diplopia, and weakness with lower limbs muscle strength rated at 3/5, and confirmed with confirmatory exams; a positive anti-acetylcholine receptor antibody (RIA), the post-synaptic neuromuscular conduction block at ENMG and the positive neostigmine pharmacological test. The patient received Neostigmine (prostagmine) 0.5 mg one ampoule in IM/day and Prednisone at a dosage of 1 mg/kg/day. The evolution was marked by a moderate improvement of the symptomatology afterward the patient was evacuated to Tunisia on family request where he received a course of immunoglobulin 2 g/kg in 2 days. The evolution in Tunisia was favorable. The patient returned in Mali and death occurred after 2 months in a context of respiratory distress. Conclusion: Myasthenia is a rare but serious disease requiring careful management and monitoring to reduce respiratory complications.

Abstract: Introduction: Hospitalization in intensive care is a source of stress and anxiety for close to the patients. Anxio-depressive symptoms appear to be common in intensive care and their prevalence is poorly evaluated. The objective of this study was to evaluate the prevalence of anxio-depressive symptoms in families. Materials and method: Observational prospective study in families of patients hospitalized in the intensive care unit for a period of 5 months. Symptoms of anxiety and depression were measured using Hospital Anxiety and Depression Scale (HADS) during hospitalization. Anxiety and depression were defined by a score greater than 10. Factors associated with the onset of anxious-depressive symptoms were sought. The prevalence of post-traumatic stress disorder in close relatives was measured by the Impact Event Scale-Revised scale (IES-R). Results: A total of 107 patients were admitted to the intensive care unit, of which 49 families agreed to participate in our study. Overall mortality was 32.2% during this period. Fifty-eight (58) patients were not included for the following reasons: death or hospitalization of less than 48 hours, refusal of families, institution, and lack of parents speaking French. Forty-nine (49) relatives completed the HADS questionnaire. Forty-three families completed the IES-R questionnaire, a return rate of 87.7%. The prevalence of anxiety was 61.2% among parents in early hospitalization. The level of anxiety was significantly associated with male parents (p = 0.035) and those with lower education (p = 0.046). The prevalence of depressive symptoms in parents was evaluated 53% at D3. Education level (p = 0.048) and male parents (p = 0.048) appeared to be a significant depression factor. The prevalence of post-traumatic stress disorder was 55.1% among the relatives of the patients. The lack of co-morbidity in admission patients was significantly associated with the occurrence of post-traumatic stress disorder in the family. Conclusion: The prevalence of anxiety and depression symptoms was high in our study. Men were at greater risk of developing these symptoms. The parents of the patients carburized appear as a population with higher risk manifestation of psychological disorders; further research is needed in this group.

Hassane Jarar Oulidi, Aniss Moumen
Journal of Geographic Information System (JGIS) , 2015, DOI: 10.4236/jgis.2015.76054
Abstract: International studies of expertise have shown that the difficulty of data access is one of the major hindrances that brakes any effort to conduct studies on groundwater. This research paper is an attempt to address this problematic through developing a technical framework to implement a Spatial Data Infrastructure (SDI) with a view to improving the status of access to data related to groundwater in Morocco, and achieving their interoperability. This prototype is primarily based on international standards (OGC & ISO) such as Web Map Service (WMS), Web Feature Service (WFS), Catalog Web Service (CSW) and Sensor Observation Service (SOS) accompanied by the use of associated specifications such as Geography Markup Language (GML) and Filter Encoding (FE). This platform is considered both as a tool for sharing updated data collected from numerous and divers source providers, and as a tool of web-based GIS for groundwater management, which constitutes the basis for decision making.

Existence and regularity of local solutions to partial neutral functional differential equations with infinite delay
Hassane Bouzahir
Electronic Journal of Differential Equations , 2006,
Abstract: In this paper, we establish results concerning, existence, uniqueness, global continuation, and regularity of integral solutions to some partial neutral functional differential equations with infinite delay. These equations find their origin in the description of heat flow models, viscoelastic and thermoviscoelastic materials, and lossless transmission lines models; see for example [15] and [38].
Semigroup Approach to Semilinear Partial Functional Differential Equations with Infinite Delay
Hassane Bouzahir
Journal of Inequalities and Applications , 2007, DOI: 10.1155/2007/49125
Abstract: We describe a semigroup of abstract semilinear functional differential equations with infinite delay by the use of the Crandall Liggett theorem. We suppose that the linear part is not necessarily densely defined but satisfies the resolvent estimates of the Hille-Yosida theorem. We clarify the properties of the phase space ensuring equivalence between the equation under investigation and the nonlinear semigroup.
