Background: In our hospital, children with appendicular plastron or abscess receive a medical treatment with cefotaxime, metronidazole and gentamicin followed by amoxicillin/clavulanic acid as an oral switch. Appendectomy is performed 10 to 12 weeks after the beginning of the discharge. A high failure rate was noticed with a switch to a second line treatments, rehospitalization or an emergency surgery. The objective of our study was to highlight predictive factors for the treatment response. Methods: We conducted a retrospective monocentric study between 2009 and 2019. Inclusion criteria were children under 16 years old diagnosed with appendicular plastron or abscess, treated with a medical treatment. We divided the cohort into a success and a failure group and compared their demographic data, clinical symptoms, inflammatory markers, abdominal imaging and antibiotic regimen. Results: Seventy-four patients were enrolled in the study and the failure rate was 36% (n=27). The median age in the success group was 8.7 years old (2-14) and 9.4 years old (2-15) in the failure group. Multiple abscesses (6.5% versus 32%, p=0.02) and diarrhea at admission (19% versus 44%, p=0.02) were significantly associated with a failure. Palpable mass (47% versus 67%, p=0.09) and stercoliths (34% versus 52%, p=0.13) appeared to be more important in the failure group. Discussion and conclusion: Several factors were analyzed to predict the response to the medical treatment for children with appendicular abscess or plastron. Patients with multiple abscesses will no longer be treated with antibiotics. We also recommended greater vigilance after detecting stercoliths in the medical imaging based on other studies results. Time to hospitalization, time to apyrexia, CRP and white blood cells level at admission were not different between the success and the failure group. Finally, a wider bacterial epidemiology study is needed in order to adjust our local guidelines and the antibiotic therapy.

This study aimed to evaluate the phytochemical properties, antibacterial and anti free-radical activities of Retama raetam extracts which is growing in the South-East of the Algeria Desert. The chemical screening showed the presence of many secondary metabolites such as tannins catechin, sterols and terpenes, and the absence of gallic tannins compounds. The obtained results demonstrated that the methanolic extract has shown moderate total phenolic and flavonoids contents (31.59 ± 2.82 mg AG E/g extract and 14.35 ±1.02 mg Qu E/g extract respectively). In the free radical DPPH test, the values of IC50 were converging in all extracts of R. raetam. The antibacterial activity of extracts has been tested against ten bacterial strains, were registered as the best inhibition zones with Vibrio cholera, Micrococcus luteus and Serratia marcescen. Pseudomonas aeruginosa ATCC 27853 and Staphylococcus aureus ATCC 25923 strains showed high resistance against most of all concentrations of extracts, and we noted the Gram-negative bacteria strains are the most sensitive to the different extracts of the plant. The qualitative analysis of extracts by using HPLC showed the contrast in presence of the phenolic compounds, such as in ethyl acetate extract registered absence of chlorogenic acid, also the absence of caffeic acid in 1-butanol extract. These results confirmed of the phenolic extracts of this plant are a source natural alternative to antibiotics and antioxidants.

This study aims to phytochemical study, antiradical scavenging and antibacterial Activity of the extracts of Cleome arabica L. from the region of Oued Souf (East South Algerian). The crud extracts two methods obtained methanolic were maceration (EM) and ultra-sound (EU). The yields were: 8.95% and 9.60%, respectively. The quantitative estimation of total polyphenols is 11.57 mg EAG/g Ex (EM) and 13.46 mg EAG/g Ex (EU). The flavonoids contents in (EM) and (EU) are respectively 5.48 and 6.19 mg EQu/g Ex. the anti-free radical activity in the extracts at (concentration 0.1mg/ml) showed a great capacity to scavenge of the DPPH• radical and the percentage of inhibition was 41% in (EM) and 60.67 % in (EU). The results of the antibacterial activity of two bacterial strains: Escherichia coli and Staphylococcus aureus, revealed that Cleome arabica L. has a significant effect on the two strains with inhibition zones variable from 0 to 12 mm for Escherichia coli and 0 to 13 mm for Staphylococcus aureus.

Gayet-Wernicke encephalopathy is a serious complication of thiamine deficiency characterized by a clinical triad: confusional state, oculomotor disturbances, and cerebellar ataxia. Alcoholism is the main cause of thiamine deficiency. Severe pancreatitis through prolonged fasting and vomiting may exceptionally give a similar clinical picture which sometimes poses diagnostic difficultiesDiagnosis is based on brain imaging by showing on MRI a T2 or FLAIR hypersignal affecting the peri-aqueductal region, the medial part of the thalamus, the floor of the fourth ventricle, the vermis, the mammillary bodies and, sometimes, the cortex. Treatment consists of rapid intravenous administration of thiamine. We report a case of 66-year-old patient followed for severe pancreatitis whose evolution was marked by the onset of a consciousness disorder whose investigations returned in favor of Gayet-Wernicke encephalopathy. &nbsp

In this paper, we propose a scheme for implementing a Toffoli gate in a system with an atom that has six levels in a lambda configuration, interacting with a high-Q cavity containing four modes. Here, we reduce a six-level system into an effective three-level behavior by applying the adiabatic elimination method. Next, we calculate the probabilities of the states of the interest as well as the fidelity. We also study the effects of photonic and atomic decay rates on the evolution of the system which is reasonably less sensitive to decoherence.

Arterial stenosis is a common cardiovascular disease that restricts blood flow. A stenotic blood vessel creates tangent stress pressure, which lessens the arterial side and causes an aneurysm. The primary purpose of this study is to investigate blood flowing via an inclination pipe with stricture and expansion after stricture (widening) underneath the influence of a constant incompressible Casson liquid flowing with the magnetism field. The relations for surface shearing stress, pressure drop, flow resistance, and velocity are calculated analytically by applying a mild stenosis approximation. The effect of different physical characteristics on liquid impedance to flowing, velocity, and surface shearing stress are studied. With a non-Newtonian aspect of the Casson liquid, the surface shearing stress declines, and an impedance upturn. Side resistivity and shear-stress increase with the elevations of stricture, whilst together decreasing with a dilatation height.

The current study describes the chemical composition and insecticidal activities of the essential oils (EOs) extracted from Lavandula dentata L. and Lavandula stoechas L. against the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), a worldwide fruit pest. Gas chromatography (GC) and GC-mass spectrophotometry (GC-MS) analyses revealed that L. dentata oil contained camphor (50.8%), 1,8-cineole (6.6%), β-selinene (5%), and borneol (3.2%) as major components. On the other hand, L. stoechas EO was characterized by high contents of camphor (44%), camphene (14.8%), fenchone (9.1%), and 1-10-diepi-cubenol (4.6%). The toxic impact of EOs against C. capitata was evaluated through ingestion and contact methods. All of the EOs were toxic to C. capitata, and insect mortality was dose and time-dependent. In ingestion toxicity assays, L. dentata was the most toxic oil with an LC

The umbilical hernia is common in children. Most of the cases have a spontaneous regression around the age of 3 years. Complications are very rare, and thus surgery is not routinely indicated before the age of 3 years. We report an exceptional case of spontaneous rupture of an umbilical hernia with emphasis on the management of this rare complication and a literature review of similar cases.

Background: Honey is generally evaluated by physicochemical analysis of its constituents. The manipulation of honey and its possible adulteration is reflected in many of its physicochemical properties. Objective: In this study, samples of Zygophyllum album L honey produced in El-Oued, Algeria, were characterized based on their melissopalynology, physicochemical and antioxidant properties, also polyphenol content. Methods: The physicochemical parameters of honey, such as density, moisture content, pH, free acidity, electrical conductivity (EC), total sugar content, color intensity, water insoluble solids content, hydroxymethylfurfural (HMF), ash, specific rotation, were measured. A number of antioxidant tests were performed to determine the antioxidant properties of Zygophyllum album L honey samples. The polyphenol in the Zygophyllum album L honey was measured by spectrometric determination based on folin-ciocalteu’s method. The identification and quantification of phenolic compounds were carried out by RP-HPLC (high-performance liquid chromatography). Results: All honey samples contained monofloral (67.83-91.89%) pollen belonging to Zygophyllum album L. The results of physicochemical parameters of analyzed honeys were: pH 4.33, moisture 17.2%, free acidity 41.96 meq/kg, electrical conductivity 0.408 mS/cm, HMF 11.89 mg/kg, Ash 0.246 (%), specific rotation -8.21. The Zygophyllum album L honey was extra white amber. The total sugar content ranged from 81.5 to 83. Honey samples contain high levels of gallic acid (252.53±15.56 mg/kg honey), chlorogenic acid (124.71±10.09 mg/kg) and low amounts of total polyphenol (467.82±46,98 mg GAE/kg). Conclusion: Physicochemical parameters (total acidity, pH, moisture, dry matter, ash, and qualitative hydroxymethylfurfural) were within the approved limits established by International Honey Commission.

Los lugares de interes son particularmente sensibles a las amenazas, particularmente las de origen antropico. EnglishThirty stations at the El Kala National Park (North Eastern Algeria) were the subject of a floristic focused on the study of the ecology of bulbous and tuberous geophytes. The floristic analysis was used to draw up a checklist of 67 species belonging to 36 genera and 14 families, among of which 19 species a high proportion of rare and /or endemic taxa; among them six signed taxa are endemic to algerian-tunisian mainly represented by family of Orchidaceae. In this work, we recorded the presence of a new species for the Algerian flora which is Ophrys fusca subsp. lupercalis. Multivariate analyses revealed certain environmental variables determining the distribution of geophytes. The visited sites show an alarming vulnerability and subject to threats, particularly anthropogenic ones.

The United Nations (UN) adopted the seventeen “Sustainable Development Goals” (SDGs) in early September 2015. One of these goals is SDG 11, which refers to the sustainable cities and communities. In this context, local governments face the challenge of aligning with this objective. As a result, they are increasing outreach to their organizational boundaries to involve citizens in policy making and strategy development, continually listening to citizens’ voices. One of the methods citizens use to express themselves is social media. This paper will emphasize social media platforms and specially Twitter to explore the public discourse about cities in the context of SDG 11. We applied descriptive quantitative and qualitative analysis to analyze the tweets that include terms and hashtags referring to the SDG 11. The data analysis process is composed of three major procedures: 1-Engagement analysis, 2-Trends based analysis and 3-Data Insights. Our results show that: 1-the COVID’19 pandemic negatively impacted users engagement towards SDG 11, 2-new technologies such AI and IoT are gaining more importance to help cities reach SDG 11, and 3-the SDGs are related and one SDG can impact other SDGs.

Governments can use social media platforms such as Twitter to disseminate health information to the public, as evidenced during the COVID-19 pandemic [Pershad (2018)]. The purpose of this study is to gain a better understanding of Canadian government and public health officials’ use of Twitter as a dissemination platform during the pandemic and to explore the public’s engagement with and sentiment towards these messages. We examined the account data of 93 Canadian public health and government officials during the first wave of the pandemic in Canada (December 31, 2019 August 31, 2020). Our objectives were to: 1) determine the engagement rates of the public with Canadian federal and provincial/territorial governments and public health officials’ Twitter posts; 2) conduct a hashtag trend analysis to explore the Canadian public’s discourse related to the pandemic during this period; 3) provide insights on the public’s reaction to Canadian authorities’ tweets through sentiment analysis. To address these objectives, we extracted Twitter posts, replies, and associated metadata available during the study period in both English and French. Our results show that the public demonstrated increased engagement with federal officials’ Twitter accounts as compared to provincial/territorial accounts. For the hashtag trends analysis of the public discourse during the first wave of the pandemic, we observed a topic shift in the Canadian public discourse over time between the period prior to the first wave and the first wave of the pandemic. Additionally, we identified 11 sentiments expressed by the public when reacting to Canadian authorities’ tweets. This study illustrates the potential to leverage social media to understand public discourse during a pandemic. We suggest that routine analyses of such data by governments can provide governments and public health officials with real-time data on public sentiments during a public health emergency. These data can be used to better disseminate key messages to the public.
