Purpose: Report radiographic aspects and assess the contribution of computed tomography for the diagnosis and search for extension of bronchial carcinoid tumors. Material and methods: This retrospective study included 9 patients with a bronchial carcinoid tumor during a four years period. In all patients, the exploration included standard chest radiography, computed tomography (CT) and abdominal ultrasonography. Results: This series included three females and six males, mean age 25 years (age range 20-52 years). The average time between clinical symptoms and diagnosis was 24 months. The important signs were chest pain, dry cough and dyspnea in 7 cases, hemoptysis in 4 cases. Chest radiography has objectified a rounded opacity speculated in 4 cases, opacity systematized in 3 cases and an opaque lung in 2 cases. Computed tomography (CT) revealed an endobronchial process with a endobronchial budding in 5 cases, pneumonia systematized in 4 cases, collapse in 7 cases, a localized dilatation of bronchus in 2 cases, lymph node metastases in 4 cases. Bronchoscopy has the macroscopic diagnosis in all cases. All patients have surgical treatment, the lobectomy in 4 cases, pneumonectomy in 3 cases and bilobectomy in 2 cases. Conclusion: CT is indispensable for positive diagnosis, and topographic localization of extension of bronchial carcinoid tumors. The main contribution of CT compared with fibroscopy is to demonstrate exobronchial tumor development and upstream pulmonary complications. [ABSTRACT FROM AUTHOR]

Effects of the Association of Compost and Mineral Fertilizer on the Productivity of Cotton and Maize Cropping System in Burkina Faso. To improve the productivity of a cotton - maize rotation using organic and mineral fertilization, a study was carried out in experimental station from 2008 to 2010. Five levels of compost (0, 2, 6, 9 and 12 t of dry matter ha­1) combined to four rate of mineral fertilizer were compared in split­plot statistical design. The physical and chemical characteristics of soil, crop yields, as well as the mineral nutrition of maize and cotton plants were evaluated. The results show that the content of assimilable P and available K was significantly improved in amended soils by compost which had no significant effect on the carbon content. In amended soils, compost improved plants nutrition which was correct in nitrogen and potassium for cotton and deficient in nitrogen and phosphorus for maize. Compared to control soil, compost combined to mineral fertilizers increased significantly yields with a better efficacy for the recommended mineral manure. The application of 2 t ha­1 of compost per year was as effective as high doses of compost in the second year, and more effective than the latter in the third year. An economy on the recommended dose of mineral fertilizer could be considered, with an annual input of 2 t ha­1 of compost to the mineral fertilizers necessary to maintain the productivity of the cotton­cereal cropping systems.

Crops Residues Management Effects on Crops Yields and Mineral Balance in a Cotton- Maize- Sorghum Rotation in Burkina Faso. The effect of crop residues management on crops yields and nutrients balances in a cotton-cereals cropping system was studied in a long-term experiment carried out from 1982 to 2006. The experimental design was a simple nonrandomized blocks comparing extensive management of crops residues (T1), semiintensive management of crops residues (T2) and intensive management of crops residues (T3). Crops yields, soil chemical properties and mineral balances were measured. Results showed that after 25 years, soil carbon contents decrease was respectively 44%, 15% and 13%, with an extensive, semi-intensive and intensive management of crops residues. Total phosphorus decrease was 25% in all the treatments. Exchangeable Ca and Mg declined from 2.43 to 1.37 cmol+ kg-1 and 0.9 to 0.29 cmol+ kg-1 respectively while the Sum of Exchangeable Bases declined from 3.79 to 1.79 cmol+ kg-1. Recycling crops residues to compost and manure increased cotton yields from 13 to 22 %, maize yields from 45 to 60 %, and sorghum yields from 19 to 44%. Mineral balance in N, P, K and S was improved after 25 years of continuous cultivation while using compost or manure. At the same time, the decline of soil properties was due to nutrients losses which need to be evaluated. This study recommends integrated crops residues management and the use of rock phosphate to improve sustainability in cottoncereals cropping systems.

Serological Diagnosis of Sudano-Sahelian Isolates of Rice Yellow Mottle Virus (RYMV). Rice Yellow Mottle Virus (RYMV) is the most damaging virus infecting rice in Africa. Serology is a suitable detection method for RYMV but most available anti-RYMV polyclonal antibodies react poorly with some isolates of the virus, which undermine the reliability of the method. A broad-spectrum polyclonal antibody was raised against Rice Yellow Mottle Virus (RYMV) in order to improve the serological detection of the virus. This antibody was used to diagnose the virus in field samples collected from both irrigated and upland rice and wild host plants in five West and Central African countries (Burkina Faso, Cameroon, Chad, Mali and Togo). RYMV was readily detected in about 500 samples whereas a new natural host species (Eragrostis atrovirens) collected from Mali was identified. The viral isolates gathered in this study constitute the starting point for a reference collection of plant viruses in the Sudano-Sahelian region. This collection will be particularly useful for the assessment of RYMV variability which is a key factor in developing rice varieties with stable resistance to the virus.

Compared Effects of Two Formulations of a Mineral Fertilizer on Yield and Mineral Nutrition of Cotton in Burkina Faso. The high cost of mineral fertilizers is the main constraint in cotton production. Experimentations were led during 2 years on 4 sites of cotton production area of Burkina Faso. The bulk formulation of cotton mineral fertilizer was compared to the complex formulation commonly used in cotton production. The experimental design is a block Fisher with 4 treatments and 6 replicates. The following treatments were applied: control without fertilizer, complex formulation of the mineral fertilizer, bulk blending formulation of the mineral fertilizer, local bulk formulation of the mineral fertilizer. N, P, K, S and B were respectively applied at constant rates of 44; 44.5; 21; 9 and 1.5 kg/ha on fertilized soils. The results showed that on acidic soils, with low organic matter content, no significant difference was obtained between the complex and the bulk formulation of the mineral fertilizer, with respect to the yields. Cotton mineral nutrition was supplied as well by the bulk as the complex formulation and this explained the high nutrition indexes (>100) for N, P and S. The bulk formulation with a lower cost than the complex formulation and an agronomic efficiency equivalent to that of the complex formulation, confirms the interest of using this formulation in cotton production.

Optimizing Sample Surveys in Farming Systems Research. The collection of agricultural data, essential for Farming Systems Research, is expensive and the quality of the estimated statistics directly linked to the available budget. This paper shows how to calculate estimator precision of sample surveys from a small number of basic parameters, and how to compare it to a cost function for an optimal resource allocation. Basic parameters are calculated for key variables of the data base of the Farming System Research Team of Sikasso, Mali, and the estimator precision is derived for a number of options. It is shown that this precision can only be very modest with a minimal mean square error of 5 % to 10 %, for the typical small sample size (12 villages, each with 8 farms). Increasing the number of villages diminishes this error, but the effect of an increasing number of farms per village decrease quickly above six to eight farms per village. This type of surveys should therefore not be used for agricultural statistics. They do produce indicators of limited precision, but independend and readily accessible. They are better suited to analyze relationships between variables, to link causes wich constraints and reasons with technology adoption, and to follow major changes in the system's evolution.

Abstract: Objective: The vaccination of hospital staff decreases patient mortality and disorganization of services due to sick leave. The main aim of our study was to determine the Clermont-Ferrand University hospital (CHU) personnel’s motivations for or against antiflu vaccination to increase the effectiveness of prevention campaigns. Design: An autoquestionnaire with multiple choices was given to the 7601 CHU staff in May 2005. It documented socioprofessional characteristics, vaccinal status, and reasons for vaccination, nonvaccination, or stopping antiflu vaccination. Results: The answer rate was 26.5% (2011 autoquestionnaires returned) and representative of the CHU staff. The rate of vaccination in 2004 was 36.35% with a strong correlation between vaccination and former influenza infection (p <0.001). Five of the six principal reasons for vaccination were altruistic including the first two: avoiding transmission to patients (61.8%) and his family (59.8%). The main reason for stopping was the lack of time. The reasons for nonvaccination were linked to a feeling of invulnerability: conviction of not being at risk, of being too young, or in good health. Conclusions: The Haute Autorité de santé’s objective of vaccinal coverage against influenza for 75% of the health professionals requires their active compliance. The effectiveness of future campaigns could aim at improving knowledge by insisting particularly on the young age of the risk populations. The lack of time can be compensated by offering on-site vaccination, including at night and by proposing larger schedules for vaccination. [Copyright &y& Elsevier]

Introduction et objectifs: L’incidence exacte des complications, notamment infectieuses, des Catheters à Site d’Injection Implantable (CSII) est difficile à apprécier dans la mesure où les études publiées sont majoritairement rétrospectives. Matériels et méthodes: Étude prospective du 12 mai 2008 au 10 juillet 2008 mobilisant quotidiennement 1 ARC par service mesurant l’incidence des complications précoces et tardives, en particulier infectieuses dans deux services de cancérologie du CHU de Clermont-Ferrand. Résultats: 248 patients âgés de 24 à 85 ans ont été inclus. La notion d’une complication antérieure à l’étude était retrouvée à l’interrogatoire chez 9 % des patients dont 5 cas d’antécédent d’infection de CSII (dont 4 survenues dans les deux mois qui ont précédés le début de l’étude). Pendant la durée de l’étude sont survenues 2 complications précoces (un hématome et un déplacement) et 4 complications tardives (2 thromboses, 1 hématome et une absence de retour veineux). 3 patients (1,2 %) ont eu une infection conduisant à l’ablation du CSII, ce qui représentait la première cause d’infection motivant la prescription d’une antibiothérapie pendant la période de l’étude (les autres infections étant une pneumonie et une pyélonéphrite). L’incidence des infections de CSII était de 0,21 pour 1000 jours de cathétérisme ou 3,4 infections/1 000 jours d’hospitalisation. Conclusion: Cette étude prospective montre que l’incidence cumulée des différentes complications (infectieuses et non infectieuses) liées à la pose et l’utilisation des CSII n’est pas si anecdotique et qu’elle mérite une attention particulière (measures d’incidence, évaluation des pratiques, …).

Osteoid osteoma is a benign primary bone tumor. This tumor is relatively frequent, accounting for 12% of all benign bone tumors and about 2-3% of all bone tumors. We report a new case of osteoid osteoma confirmed histologically. A 30-year old patient was referred for evaluation of chronic ankle pain. Front and lateral radiographs of the ankle showed a heterogeneous lesion located in the neck of the talus without soft tissue abnormalities. The CT scan of the ankle showed a nodular, hypodense lesion located in the neck of the talus with a limited osteosclerotic reaction.

Introduction: Aseptic osteonecrosis of the femoral head is the partial or total destruction of the femoral head due to impaired blood flow. It affects young adults (30-60 years), predominantly male (3 male:1 female) and is often bilateral. The aim of the present work is to define the role of MRI in the diagnosis, classification and therapeutic management of osteonecrosis of the femoral head., Materials and Methods: This study focused on three observations of osteonecrosis of the femoral head in the 20 Aout Radiology Department of the Ibn Rochd of Casablanca University Hospital with a review of the literature. All patients underwent MRI of both hips with sagittal sequences, coronal T1, T2 and T2 SE DP Fat Sat., Results: The ages of our patients were 62 years for case 1 (male); 37 years for case 2 (female) and 58 years for case 3 (male). The MRI in all 3 patients objectified: subchondral bone fragment on the outer compartment of the femoral head bilaterally with minimal bilateral effusion in the first patient. In the other two patients, we note the presence of subcortical signal abnormalities of the femoral heads with demarcation piping T1 hypointense, T2 hyperintense and associated subchondral fractures. A minimal effusion was also observed., Conclusion: Medical imaging is an essential element of the radiological diagnosis of osteonecrosis of the femoral head. MRI finds its best indication in the precocious and differential diagnosis, as well as the classification of osteonecrosis of the femoral head., (Le comitée de rédaction se réserve le droit de revoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

The CS child, aged 9, is evacuated from a health center located 200km away from Ouagadougou (capital of BF) for decompensated heart failure. Clinically we noted a syndrome of congestive heart failure. No obvious cause has been found outside of the advancing age of parents (50 years) and the potential risks of rubella infection. A Doppler echocardiography revealed a fistula aorto-pulmonary 17mm wide associated with a pericardial effusion of average circumferential abundance and a dilation of the left ventricular. Pulmonary radiography showed a large cardiomegaly and left pleurisy. The discovery of congenital heart disease between 2 and 4 years is very rare but the prognosis is good with surgical treatment., (Le comitée de rédaction se réserve le droit de revoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

CA, 14 old years, female, born last uterine siblings of 9 children, 4 died of various causes, was admitted in the pediatric service of CHU-YO for functional impairment of the lower limbs. Physical examination revealed swelling and deformation harsh, uneven surfaces, the circumferential upper and lower limbs and lumbar spine associated with spastic paraplegia. Sphincter disturbances accompany this clinical picture. The radiographic bone marrow hypertrophy individually with images of exostosis at the epiphyses. Multiple exostosis or BESSEF Hogen's disease is rare and has a reserve functional prognosis because of outcome of low spinal cord compression and vascular compression. We felt it appropriate to bring this case discovered during our clinical practice because of its rarity and the risk of malignant degeneration., (Le comitée de rédaction se réserve le droit de revoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

Objectives: To evaluate a strategy based on screening and isolation at admission to a department of infectious diseases during an epidemic of vancomycin-resistant Enterococcus (VRE) at the University Hospital of Clermont-Ferrand., Methods: Systematic screening for VRE by anal swabs began on November 15, 2004. Patients were isolated on admission if (a) they had been hospitalized more than 24 h in an at-risk department of our hospital or (b) they had received a course of wide-spectrum antimicrobial therapy for longer than 48 h in the three months preceding admission. Patients hospitalized in our department were screened weekly if they were treated with wide-spectrum antibiotics, had a urinary catheter left in place for one week, or were neutropenic., Results: Through May 15, 2005, 12 (3.5%) of 341 swabs were found to be positive for VRE: eight were detected on admission and four during hospitalization. In all, 81 patients were isolated on admission. A case-control study confirmed that the criteria for patient isolation were indeed risk factors for VRE. Isolation was well accepted when it was clearly explained. No new case has been detected since March 2005., Conclusion: An isolation strategy based on known risk factors for VRE with systematic screening on admission appears to be an effective way to control an outbreak of VRE, perhaps in part because it helps to keep the medical staff alert to this problem. Isolation is well tolerated as long as it is explained clearly.

Introduction: The aim of this study was to evaluate the antibacterial effectiveness of 2.5% sodium hypochlorite on endocanal bacteria related to the time contact Within root canal., Materials and Methods: 110 teeth were prepared and inoculated with Enterococcus feacalis. All teeth were irrigated with a same volume and exposed a period ranging 1 to 10 min. Canals were sampled before and after time contact., Results: All time reduced the number of bacterial cells within the root canal (p > 0.05). There was no significant difference after the time contact of 3 min (p > 0.05). Lack of effectiveness might be caused by irrigant to reach microorganism in dentinal tubules.

By a prospective study in one year time, the authors noticed that female genital mutilation complications were 7.3 per cent of external gynecologic consultations and most complications were overdraft between 15 and 24 years old (36 cases out of 49). The main consultation motives were dyspareunia and difficult sexual relationship. Surgery under local anesthetic was very efficient (more than 90% success) and cheaper than surgery under general anesthetic.

This study was performed to determine the incidence of sore throat 24 h after tracheal intubation in 1,268 patients ASA I or II, who had undergone elective surgery. A data form was completed. Nosing were age, sex, type of surgery, anaesthetic drug, muscle relaxant, number of intubation attempts, duration of intubation, and presence of sore throat. The incidence of sore throat was 15.06%. It was significantly higher in females than in males (19.29% vs 11.66%; P < 0.01). There was a significant difference between those patients who received fentanyl and those who received pethidine (P < 0.05). There was also a greater incidence after thyroid surgery (P < 0.01). There was no correlation between sore throat and variables such as age, muscle relaxant, narcotic drug, number of intubation attempts, or duration of intubation. Lidocaine jelly and the appropriate analgesic drug reduce the incidence of sore throat following tracheal intubation.
