Pleomorphic Nasopharyngeal Liposarcoma: An Aggressive Tumor

Nasopharyngeal liposarcoma is an extremely rare clinical entity. Less than ten cases have been reported in the literature. It mainly occurs in humans. The non-specificity of the clinical and radiological signs explains the difficulty of the diagnosis confirmed by anatomopathological and immunohistochemical examinations. Its pathogenesis remains obscure and often correlates with genetic abnormalities. Pleomorphic liposarcoma is its rarest subtype, remarkable for its aggressiveness and rapidity of growth. Complete surgical excision remains the treatment of choice. We report a case of liposarcoma whose diagnosis was made during histological examination coupled with immunohistochemistry. .

Cervical Meningocele about 2 Operated Cases

Cervical meningoceles are the least common forms of spina bifida, representing between 4% to 8% of all spinal dysraphisms. They are not accompanied by neurological deficit in childhood but attached cord syndrome can occur with growth. Surgical treatment, in addition to avoiding rupture and correcting the aesthetic damage, will preserve neurological functions. We report 2 cases that we took care of. They are a 5-month-old infant and a 3-year-old girl. The first presented a 7 cm rounded meningocele pedunculated through the C1 lamina defect. The second presented an 8.6 cm polylobed meningocele pedunculated through the C2 lamina defect. They both underwent surgery with good progress.

Giant Cerebriform Nevus Cell Nevus of the Scalp: A Case Report

Giant cerebriform nevus cell nevus of the scalp is an extremely rare form of congenital melanocytic nevus. Giant cerebriform nevus of the scalp has a major psychosocial impact because of its unsightly appearance with fetid maceration. We report the case of a 35-year-old woman who had a painless, malodorous swelling of the cerebriform scalp measuring 20 × 17 cm in diameter with a wide base of insertion at the occipital level adhering to the deep planes. The excision associated with a skin plasty was carried out. Histology concluded that there was a giant cerebriform naevo-cellular nevus of the scalp.

Development of an Intelligent Queue Manager That Takes Account of the Social and Health Context

Virus prevention has been considered central to the fight against the COVID- 19 coronavirus pandemic. To limit the spread of the virus in public places, several measures have been taken, in particular respect for barrier gestures. This work is part of this dynamic and sets up a new wireless version of an electronic and nominative queue manager using artificial intelligence for more equity, inclusion and solidarity. This system, named Gifa is developed in our laboratory. The first prototype, whose connections are largely provided by a wired system with an artisanal acquisition module, is difficult to deploy for general public use, especially in buildings already built. This article deals with an artificial intelligence queue management system, presenting more functionalities, whose access to the service is ensured in very large part by wireless exchanges with a modern acquisition module realized by 3D printing. The flexible and autonomous design of this device makes it particularly easy to deploy on premises open to the public without having to modify the existing installation for commissioning. The manager is equipped with a configuration terminal, and at the counters the call is made by a cashier also equipped with a tablet connected to the wifi network. Its display screen shows certain information relating to the identity of the customer such as his face, his order number, his first name and last name. This reduces the authentication time of the person at the checkout, queue bypasses for more fairness and less stress. This work has resulted in the improvement of queue management systems by giving them more flexibility to make them more adaptable in several types of environments and other contexts.

Autonomous Robot with Artificial Intelligence for Taking Health Constants

Health facilities are generally short-staffed and overworked. This has a significant impact on the reliability of the acquisition of health constants required at the start of diagnosis. Manual acquisition and transmission of these constants and other data leads to delays in the execution of successive care-related tasks. What’s more, the quality of service is sometimes compromised by a lack of communication between patients and staff. In pediatrics, this is compounded by the difficulty of diagnosis in the face of children’s silence, intimidated by the hospital environment. Technological assistance would relieve healthcare staff of the need to perform certain repetitive tasks. The solution proposed in this document studies a robot, based on electrical, electronic, computer and artificial intelligence resources, with human-machine interaction for taking vitals and health data in health facilities. This system enables height, mass and temperature to be taken autonomously and without contact. The algorithm we’ve developed uses artificial intelligence to check the conditions for correct measurements, both bareheaded and barefoot. This solution also alerts you to epidemic trends such as obesity. This health data is made available in the healthcare facility on terminals such as tablets, smartphones and computers used by nursing staff. This work will help healthcare staff to take automatic health vitals without contact, and to acquire and circulate data via a computer network.

Cervical Spine Cord Injury Associated with Klippel-Feil Syndrome: A Case Report

Background: Klippel Feil syndrome (KFS) is a congenital malformation characterised by the presence of, at least, one fused cervical segment and results from faulty segmentation along the embryo’s developing axis during weeks 3 - 8 of gestation. The KFS increases the risk for spinal cord injury after minor trauma as a result of the disturbance of the biomechanics of the cervical spine. Persons with KFS often have associated congenital anomalies. Aim: The purpose of this study was to show the surgical management difficulties of this pathology in a low income country such as Senegal and to make a review of the literature. Case presentation: A 32-year-old man developed a tetraparesis secondary to a fall from his height while carrying a bag of rice on his head. Radiological explorations revealed fusedC2-C3 and C4-C5 vertebral bodies with a C3-C4 disc herniation associated to a spine contusion. The patient underwent surgical removal of the herniated disc via an anterior approach followed by interbody fusion and anterior plating. A complete recovery was noted at 4 months follow-up. Conclusion: Understanding of the cervical spine biomechanics of Klippel-Feil anomaly may allow an optimal management of patients. Patients with KFS should be warned of the increased risk of spinal cord injury after a low velocity trauma. Timing for surgery should be shortened.

Chemical Variability and Antibacterial Activity of Eucalyptus camaldulensis Essential Oils from Senegal

1,8-cineole, also known as eucalyptol, is the main constituent and the most important of the leaf oils of many species of the genus Eucalyptus. In present study, the essential oils isolated by hydrodistillation from the leaves of Eucalyptus camaldulensis from six different locations were analyzed by GC-FID and GC-MS. Essential oil yields ranged from 0.33% to 4.35%. In total, 34 constituents were identified, accounting for 94.0% to 99.8% of the total compositions. 1,8-cineole (46.4% - 84.4%) was the main constituent of all the essential oil samples, except for one sample collected in the Fatick region, which had p-cymene (46.4%) and 1,8-cineole (26.0%) as major compounds. The essential oil showed excellent activity against S. aureus, E. coli and E. faecalis (IZ = 25.3 ± 1.2 mm;18.7 ± 0.6 mm;17.8 ± 0.3 mm, respectively) and moderate activity against P. aeruginosa (IZ = 10.8 ± 0.8 mm). They may have potential applications in food and pharmaceutical products.

Quality of Well Water Used for Market Gardening from Lendeng Area Located in Common of Rufisque (Senegal)

This study analysis was conducted to know the quality of well water around the market gardening area of Lendeng located in the common of Rufisque Est (Senegal). In this study, six groundwater samples were taken near the Lendeng market gardening area. The physicochemical parameters of water such as pH, temperature, electrical conductivity (EC), calcium (Ca2+), magnesium (Mg2+), potassium (K+), iron (Fe2+), chloride (Cl-), sulfate (SO3-4) and phosphate (PO3-4) were measured. The analysis results obtained show sulphate and phosphate have the highest levels. These results were compared to drinking water standards from the World Health Organization (WHO). The correlation coefficient ANOVA was applied to the test result of the samples. The statistical study showed that the well water in the market gardening area of Lendeng is not polluted.

Thoracolumbar Spine Fracture-Dislocation without Neurological Deficit: A Case Report and Review of the Literature

Background: Thoracolumbar spine fracture-dislocations are very unstable and usually secondary to high energy trauma. Due to disruption of the entire vertebrae columns, the absence of neurological deficit is exceptional. Aim: The purpose of this work is to report our experience in the management of this entity in a context of limited resources and to make a review of the literature. Case presentation: A 30-year-old man was admitted with a severe low back pain after a traffic accident. Neurological functions were intact after examination. Radiological assessments revealed a complete L3-L4 fracture-dislocation. The patient underwent an open posterior reduction and internal long segment fixation. The post-operative was marked by a surgical site infection treated with surgical debridement and targeted antibiotic therapy. The neurological functions were preserved. Conclusion: Fracture-dislocations of the thoracolumbar spine are caused by high energy trauma and are remarkably unstable lesions. When they are associated with intact neurorological functions, reduction and stabilization of these fractures are a challenge.

Trace Metals in Mussels <i>Mytilus galloprovincialis</i>from Dakar Coast (Senegal)

Mussel samples from the Dakar coast (Senegal) were analysed using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Microwave acid digestion was also employed for metals (Mn, Pb, Cd, As) determination. Dakar coast usually receives numerous domestic and industrial discharges without prior treatment. The contents of Arsenic were, in all cases, higher than other metals. However, the bivalve molluscs present themselves as effective bio-monitors when assessing marine aquatic pollution by contaminants in the Dakar coast. The ANOVA analysis allows concluding that significant differences were found between mussels from different sampling points. In all cases, the February samples have in all cases a higher content than those collected in October.

Electronic System Using Artificial Intelligence for Queue Management

The Covid-19 pandemic has brought changes in behaviour in public places. Indeed, the health and political authorities, in order to fight against the virus in a preventive manner, require the respect of barrier gestures: social distance, mask, vaccine, gel. Still in terms of public health, long waits in a place for a service have a negative impact on the health of fragile categories such as the disabled, pregnant women and the elderly. The technical devices used for queue management must now take into account the health context, identity, particularity and behaviour of people. This paper presents an electronic system developed with artificial intelligence for queue management in public facilities. This design personalises the user’s ticket by automatically integrating the name, facial image, age and possible disability status. At the counters, a system of name calling, sound and screen display, allows users to follow the queue without having a ticket printed on thermal paper with a high carbon footprint. This solution also makes illiterate users autonomous in the queue, allowing them to maintain their dignity and to respect the safety distance between people. The device allows the establishment’s manager, depending on the context, to activate positive discrimination of the disabled or the elderly, to control the Covid-19 mark or the health pass by QR Code. This queue manager performs biometric authentication by facial recognition before the user is registered in the queue register, which prevents fraud by people who do not want to respect the order of arrival of users. This work has led to the improvement of the technical management of queues by introducing more equity, inclusion, solidarity, health and ecology.
