Background: Cystic echinococcosis is a zoonotic infection that occurs worldwide. Humans are infected through ingestion of parasite eggs in contaminated food, water or through direct contact with infected dogs, which are the definite host. Humans serve accidentally as intermediate host, and occurrences are common in children and young adults. Cystic echinococcosis is endemic in Mediterranean, South American, Middle Eastern, Central Asia, East Africa countries and Australia. Multiple cerebral hydatid cysts are very rare with only a few reports in the literature. Case Description: We present the case of an 8-year-old girl who presented with focal seizures, hemiparesis, headache, vomiting and bilateral optic atrophy. Diagnostic workup was performed, and magnetic resonance imaging revealed multiple intracranial cysts predominantly in the right frontal region with significant mass effect. A total of 11 intracranial cysts were removed surgically, and the child recovered uneventfully. Conclusion: Neurosurgeons should keep hydatidosis in the list of differentials when evaluating patients with cystic diseases of the brain. Although the removal of such cysts is challenging, outcomes are excellent when cysts are evacuated without rupture and patients show complete resolution of symptoms.

Background: A number of meningeal neoplastic lesions may radiologically and clinically simulate meningioma, include hemangiopericytomas, solitary fibrous tumors, schwannomas, hematolymphoid lesions, metastases, and others very rarely, also may clinically mimic meningiomas. Case Description: We present the case of A 28-year-old male patient, with no notable medical history, who presented with worsening headaches for 3 months, imbalance, and visual deficits, An initial MRI revealed extra-axial lesion involving the right Parieto-occipital, The tumor was hypointense on T1-weighted MR images, hyperintense signals on T2-weightedMR images, and heterogeneously enhanced suggestive of a meningioma, total resection was achieved, and the histopathological analysis confirmed the diagnosis of an angioblastic meningioma. However, 15 months later, the patient presented with the same initial visual complaints. A subsequent MRI showed lesion recurrence, leading to a second surgical intervention. The histopathological analysis confirmed the diagnosis of an anaplastic xanthoastrocytoma. Conclusion: This represents an unusual location for an anaplastic pleomorphic xanthoastrocytoma, which should broaden the differential diagnosis of extra-axial lesions.

In this work, we propose an approach for the verification of the AADL architecture. This approach is based on Model Driven Engineering (MDE) and assisted by a toolchain. Indeed, we define a source meta-model for AADL and a target meta-model for the timed automata formalism;we define a transformation process in two steps: the first is a Model2 Model transformation which takes an AADL Model and produces the corresponding timed automata model. The second transformation is a Model2 Text transformation which takes a timed automata model and generates a text in ta-format code. This code is accepted by the Uppaal toolbox. A case study has been developed to show the feasibility and validity of the proposed approach.

Introduction: A case of lumbar artery pseudo-aneurysm after surgery for lumbar vertebra burst fracture is presented. Only two cases secondary to spinal trauma and revealed after surgery have been described in the literature. A review of literature was conducted and a possible relationship with burst fracture or reduction maneuvers was discussed. Case Presentation: Here, we report a post traumatic lumbar burst facture with incomplete motor deficit of lower limbs after a fall. Surgical reduction and stabilization via posterior approach were performed. Post-operatively, a hemorrhage through surgical wound had been noticed. Pseudo-aneurysm of the lumbar artery at L3 level was diagnosed and embolisation was performed. Conclusion: This is a rare case of pseudo-aneurysm occurring in the setting of surgical stabilisation after a trauma. It was revealed by a hemorrhage discovered as a late complication. We should be aware of such potential complication as a delayed post surgery event in order to adapt the care.

Drinking water is water that does not contain pathogens or chemicals at levels that may be harmful to health. Beni Mellal region, one of the major rich areas in ground and surface water in Morocco (the rivers like Oum Errabia, Darna, ...;Bin el-Ouidane and martyr Ahmed el Hansali dams and sources like Ain Asserdoune, …) is located in the North-Centre of Morocco. The main objective of the present study was to evaluate the microbiological quality of different drinking waters originated from sources, faucets, fountains and wells in the Beni Mellal city and its agricultural surrounding areas. For this, hygienic quality indicator parameters of water quality were determined by assessing the analysis of Total Coliforms Count, Fecal Coliforms Count, streptococcus D and revivable germs while germs such as Anaerobic Sulphite-reducing Bacteria, S. aureus and Salmonella sp, were carried out according to national and international standards. The analysis of the microbiological results found for all the different samples waters investigated in this study revealed that the waters originated from fountains, faucets and sources were proper for main consumption at microbiological point of view while the wells waters were improper for consumption according to norms. Finally, it appears, from the results obtained, that the potential risk of infection of water consumers especially (groundwater) calls for prompt intervention in order to alleviate the potential health impact of water-borne diseases in the community. From this, a proper sanitary survey and implementation of water and sanitation projects in the community is recommended.
