Kyste hydatique du masséter: a propos d’un cas

La localisation cervico faciale et particulièrement musculaire massétérine est exceptionnelle même en zone d’endémie. Le kyste hydatique au niveau de cette localisation pose un problème de diagnostic et des difficultés thérapeutiques du fait de la présence de filets nerveux du VII. Les auteurs rapportent un cas rare de localisation primaire d’un kyste hydatique au niveau du muscle masséter.Mots clès : Kyste hydatique, face, masséter, imagerie, chirurgie

Mucormycose rhinosinusienne a extension palatine

Les mucormycoses sont des infections fongiques, aigues, rares et souvent fatales. Elles touchent avec prédilection les sujets  immunodéprimés. La forme rhinocérébrale est la plus fréquente. Le diagnostic repose sur l’examen clinique, anatomopathologique et mycologique. L’approche thérapeutique doit être multidisciplinaire. Les auteurs rapportent l’histoire clinique d’un patient, ayant présenté une mucormycose rhinosinusienne avec atteinte du palais au décours d’une infection dentaire. A travers cette observation, ils discutent les différents aspects cliniques, les moyens du diagnostic et les modalités thérapeutiques de la mucormycose rhinocérébrale.Mots clés : Infection fongique, mucormycose rhinocérébrale, zygomycètes, pronostic, traitement

Epidemiology of Coxiella burnetii infection in Africa: a OneHealth systematic review

Background: Q fever is a common cause of febrile illness and community-acquired pneumonia in resource-limited settings. Coxiella burnetii, the causative pathogen, is transmitted among varied host species, but the epidemiology of the organism in Africa is poorly understood. We conducted a systematic review of C. burnetii epidemiology in Africa from a “One Health” perspective to synthesize the published data and identify knowledge gaps.<p></p> Methods/Principal Findings: We searched nine databases to identify articles relevant to four key aspects of C. burnetii epidemiology in human and animal populations in Africa: infection prevalence; disease incidence; transmission risk factors; and infection control efforts. We identified 929 unique articles, 100 of which remained after full-text review. Of these, 41 articles describing 51 studies qualified for data extraction. Animal seroprevalence studies revealed infection by C. burnetii (≤13%) among cattle except for studies in Western and Middle Africa (18–55%). Small ruminant seroprevalence ranged from 11–33%. Human seroprevalence was <8% with the exception of studies among children and in Egypt (10–32%). Close contact with camels and rural residence were associated with increased seropositivity among humans. C. burnetii infection has been associated with livestock abortion. In human cohort studies, Q fever accounted for 2–9% of febrile illness hospitalizations and 1–3% of infective endocarditis cases. We found no studies of disease incidence estimates or disease control efforts.<p></p> Conclusions/Significance: C. burnetii infection is detected in humans and in a wide range of animal species across Africa, but seroprevalence varies widely by species and location. Risk factors underlying this variability are poorly understood as is the role of C. burnetii in livestock abortion. Q fever consistently accounts for a notable proportion of undifferentiated human febrile illness and infective endocarditis in cohort studies, but incidence estimates are lacking. C. burnetii presents a real yet underappreciated threat to human and animal health throughout Africa.<p></p&gt

Demand Analysis of Selected Fruits and Vegetables in Oman

Consumer behavior and prospective changes in demand of food product have a significant impact on production and distribution decisions. Consumer responsiveness to changes in prices, income and other demand determinants is very important to production and market decision-makers. The present study estimates demand responses for selected fruits and vegetables in Oman using consumer aggregated national data. The main objective is to generate information needed for making public as well as private decisions. Results indicate that most fruit and vegetable consumers respond to price, and income changes in the expected manner. Responses are different from one commodity to another depending on its nature and importance in the consumer's diet habits. In a few cases income is not a significant determinant of the demand. Moreover, many fruits and vegetables have shown a relationship of substitution and complementary consistent with Omani diet. These results are useful in farmers and distributers to allow them to adjust their production and marketing services according to the consumer’s response

Purchase Behavior of Consumers for Seafood Products

Fish consumption is a key component in production and marketing decisions. Fish consumers play a key role because fishermen and distributors recognize their purchase choices as a determinant to their operation. Consumers make buying decisions according to market conditions and to various attributes of the product, namely the specie, the form, the place of purchase, the size and the quality. This study is aimed at providing information on Oman consumers’ attitudes and preferences for fish purchase form and market outlets using an information-processing model. It identifies factors for predicting changes in market demand for fish products and services as a result of changes in consumers attributes. Results indicate that on-shore fish markets are the most preferred outlets for the coastal population while retailers and Oman National Fisheries Company are the commonly used outlets. Results also show that whole fish is the most preferred form of purchase for both rural and urban medium to low-income consumers while a large proportion of high-income consumers in urban regions prefer mainly sliced fish. Market development efforts should focus on the organization of on-shore fish markets in coastal regions, and retailers and Oman Fisheries Company’s outlets in the inland areas. Forms other than whole fish may be promoted for sale in supermarkets and specialized shops for the urban high-income consumers group..
