Formed on top of the Gulf of Cadiz, the Al Idrissi mud volcano is the shallowest and largest mud volcano in the El Arraiche mud volcano field of the northwestern Moroccan margin. The development and morphology of mud volcanoes from the El Arraiche mud volcanoes group have been studied at a large scale. However, the time interval related to their formation period still needs to be better understood. In this regard, we interpreted and analyzed the seismic facies from the 2D reflection data of the GEOMARGEN-1 campaign, which took place in 2011. The aim was to identify the seismic sequences and draw the Al Idrissi mud volcano system to determine the formation period of the Al Idriss mud volcano. And as a result, the Al Idrissi mud volcano system is made of both buried and superficial bicone and was identified along with the Upper Tortonian to Messinian-Upper Pliocene facies. As the initial mud volcano extrusive edifice, the buried bicone was formed in the Late-Messinian to Early-Pliocene period. However, the superficial bicone, as the final extrusive edifice, was included in the Late Pliocene. In this case, the timing interval between the buried and superficial bicone is equivalent to the Late-Messinian to Upper-Pliocene period. Therefore, the latter corresponds to the Al Idrissi mud volcano formation period.

Introduction: Proximal humerus fractures are common, however, there is no consensus on a decision-making algorithm for the therapeutic management of these fractures, the aim of this study is to evaluate and compare functional results between two surgical techniques and to deduce the satisfactory results of the Kapandji’s pinning which, compared to the screw plate, should keep its place in the therapeutic arsenal. Patients and Methods: It’s a retrospective study, including two groups: The first of 18 patients treated with palm-tree pinning using kapandji’s technique, the second of 16 patients treated with anatomical screw plate at the orthopedic trauma service of the mohamed VI university hospital between July 2013 and July 2018. We compared the results of the two techniques by studying three parameters which are the healing time, the anatomical reduction, and the functional outcomes. The average age was 46 years, and the sex ratio (M/F) was 2.3. Results: The statistical analysis of functional and radiological results showed no significant difference between the two techniques, indeed the average healing time was 56.3 days in the group treated by screw plate and 55.2 days in the group treated by Kapandji’s pinning (p = 0.46), Constant’s score was 73.18 and 79.05 respectively (p = 0.27) and the average cephalodiaphyseal angle was 49.03° and 52.07°, respectively (p = 0.35). Discussion: This study has clearly shown, as reported in the literature, that there is no conclusive evidence to suggest superiority of os-teosynthesis by anatomical plate versus kapandji’s pinning. However, the simple achievement of pinning according to kapandji’s technique, the preservation of soft tissues and the low cost make us prefer this technique. Furthermore, despite the progress noted in the development of osteosynthesis means of the proximal humerus, percutaneous pinning should always keep its place.

The chemical composition and antimicrobial potential of Cistus munbyi essential oil were studied for the first time. GC and GC–MS analysis revealed 48 compounds representing 96.98% of the oil. Terpinen-4-ol(23.75%), meta-Cymene(17.30%), and Sabinene(12.38%)were the major constituents. Antimicrobial activity was evaluated against nine pathogens using the disc diffusion and broth micro-dilution methods. Results show that *** essential oil possesses strong antimicrobial activity against all strains, regardless if Gram-positive or Gramnegative bacteria, or yeast, with MICs values not exceeding10(mg/ml). In addition to its efficacy, C. munbyi essential oil has an unusual antimicrobial potency which is attributed to its specific chemical composition. Thus, findings presented here suggest that endemic C. munbyi contains a very interesting essential oil that may be valuable in several areas.

Background: The local population in developing countries is at higher risk of contracting hepatitis B (HBV) due to some of the factors they practice which promote its establishment and distribution within their communities and may constitute a burden for them. Objective: This study aimed to determine the prevalence and risk factors associated with the hepatitis B virus in populations of the Algamosi region, Gezira State, central Sudan. Method: A cross-sectional study was conducted among 492 people, populations of the Algamosi region, Gezira state in central Sudan. A questionnaire was used to collect information on socio-demographic factors, transmission, and prevention of hepatitis B infections. As well, blood samples were taken from each participant, and serum was used for rapid tests for HBsAg. Positive samples were then tested by the ELISA method for confirmation. Data were obtained using SPSS version 21 and a P value of less than 0.05 was considered statistically significant. Results: The prevalence of hepatitis B was 16.10% and was higher in men than in women (05.7 - 1.00). People aged 31 to 45 had the highest prevalence of 27 (20,600%) for HBV infection. There was a significant association between HBV and age groups (X2 = 7.816 and P value = 0.05). This study also found that there was a significant association between viral hepatitis and knowledge about transmission and prevention (P value Conclusion: Although most people who live in developing countries are at high risk for transmission of hepatitis B, this indicates the need to implement the screening policy and integrate it with other health services and create awareness such as proper treatment and surveillance for hepatitis infection in all nations.

Objective: To determine factors influencing anesthesiology choice among resident doctors at the medical school of Marrakech. Materials and Methods: We have conducted a descriptive cross-sectional study based on an anonymous questionnaire. Results: A total of 406/672 questionnaires were returned, with a female/male sex ratio of 1.07. The duration of the training (OR: 3.3;CI 95%: 1.74 - 6.23;p < 0.001), intellectual challenge (OR: 3.02;CI 95%: 1.69 - 5.37;p < 0.001), doctor-patient relationship (OR: 2.22;CI 95%: 1.02 - 4.84;p: 0.04), and financial aspects (OR: 2.14;CI 95%: 1.09 - 4.21;p: 0.02) were independent factors that influenced the choice of anesthesiology. Conclusion: we recommend the succeeding: 1) Support students in their choice;2) Correct misconceptions about certain specialties;3) Promote clinical clerkship;4) Encourage mentorship;5) Increase the salary of at-risk specialties.
