    Abstract:
    Climate change is affecting rainfall variability. This paper investigated the June-September (JJAS) rainfall variability using reanalyzed and observed da-tasets from 1976 to 2015 in Togo. The rotated empirical orthogonal function (REOF) method was used to get the distribution patterns of JJAS rainfall. The Mann-Kendall (MK) statistic was also used to detect temporal trend of the ro-tated principal component time series (RPCs) that represent the modes of posi-tive loadings. The REOF method has revealed four significant patterns that ex-plained 65.1% of the total variance; the first, the second and the fourth REOF modes exhibit mainly positive loadings, whereas the third exhibits negative loadings. The first mode (REOF1) represents mainly the southern part of Togo; the second mode (REOF2) represents the northern part, the third mode (REOF3) represents the western part and the fourth (REOF4) represents the north-eastern part of Togo. The Mann-Kendall test has revealed an increasing and significant trend of rainfall in the northern region of Togo. In contrast, the trends were not significant in the southern and north-eastern parts of the coun-try. These results form a basis on which adaptation strategies may be taken in this region with high rainfall variability.
    Does Benefit Relationship Affect Analysts’ Earnings Forecast?—Evidence from Chinese Stock Market

    Open Journal of Accounting (OJAcct) , 2017, DOI: 10.4236/ojacct.2017.62003
    Abstract: Under the information asymmetrical theory, the Chinese securities analysts are affected by many benefit factors, so the purpose of the study is trying to figure out what benefit elements and how to affect analysts’ earnings forecasts. Using data from 2012 to 2015, the author creatively quantifies interest factors, and does the empirical analysis. Regression results indicate that the closer relationship between securities analysts and the listed companies management or institutional investors, the greater accuracy of their earnings forecasts. Besides, analysts’ reputation exists a negative correlation between earnings forecasts accuracy. Furthermore, securities’ underwriting relationships have no significant influence on the accuracy of analysts’ earnings forecasts, but the underwriting analysts are more likely to overestimate earnings per share of the target companies.
    Etude de la rémanence du triflumuron, inhibiteur de la synthèse de la chitine, selon la nature du tissu à l'égard de la mouche tsé-tsé Glossina palpalis gambiensis, dans une perspective de lutte autocide

    Abstract: Study of Remanence of Triflumuron, Synthesis Inhibitor, According to the Nature of Cloth with Regard to Tsetse Fly Glossina palpalis gambiensis in View of Self-killed Fight. The objective of this study is to assess the persistence of triflumuron impregated at a dosis of 9,7 g.m-2 on blue cotton, polyester and polypropylene material in comparison with the reference material made of 67% polyester and 33% cotton used in the control of tsetse fly. Impregnated materials were exposed to field conditions during six months. One sample of each material was monthly taken and tsetse flies were exposed to it to assess the effects on the reproduction parameters of contaminated flies. Two types of contamination were evaluated: 20 days old females were contaminated by exposure to impregnated tissues while teneral females (3 days old) were contaminated through the mating with males contaminated like the old females. Measured parameters were: the abortions, the pupa production, the non viable pupa and the hatching. The results from the old females showed that impregnated polypropylene material significantly reduced the average of hatching rate during six months (1 1.4%) in comparison with impregnated reference material (15.14 21%), cotton material (14 25% ) and polyester one (21.5 34.3%). For young females the same tendencies were observed. During the six months period of investigation, triflumuron persistence was better on the polypropylene material than on the reference material for the control of tsetse flies by self sterilisation.

Fourteen exergaming older adults participated. Competitiveness was assessed prior to the start of exercise. Participants were trained to ride a “cybercycle;” a virtual reality-enhanced stationary bike with interactive competition. After establishing a cybercycling baseline, competitive avatars were introduced. Pedaling effort (watts) was assessed. Repeated measures ANOVA revealed a significant group (high vs low competitiveness) X time (pre- to post-avatar) interaction (F[1,12] = 13.1, P = 0.003). Virtual social facilitation increased exercise effort among more competitive exercisers. Exercise programs that match competitiveness may maximize exercise effort.

    Abstract: Aim. To prospectively assess the effectiveness of revision with open subacromial decompression in patients who had a previous unsatisfactory outcome with the arthroscopic procedure. Methods. 11 patients were identified for the study, who did not demonstrate expected improvement in symptoms after arthroscopic acromioplasty. All patients underwent structured rehabilitation. Functional evaluation was conducted using the Hospital for Special Surgery, New York, shoulder rating questionnaire. Results. M?:?F was 7?:?4. The mean age was 57?years. The average shoulder score improved from 49.6 preoperatively to 56 postoperatively at an average followup of 16 months. Two patients showed deterioration in their shoulder scores after revision while the rest showed only marginal improvement. All except one patient stated that they would opt for surgery again if given a second chance. Conclusion. In the group of patients that fail to benefit from the arthroscopic decompression, only a marginal improvement was noted after revision with open decompression. 1. Introduction Anterior acromioplasty was first described by Neer in 1972 for chronic impingement syndrome [1]. Since then, this procedure has come to be widely accepted and many surgeons and authors have described consistent and satisfactory results for this treatment [2–6]. Ellman introduced arthroscopic decompression [7] and, in 1991 [8], in a separate study, reported on the two-to five-year results of arthroscopic subacromial decompression which indicated it to be as effective as open decompression as a primary procedure [9–13]. The benefit with arthroscopic repair lies with its recovery time. Mean hospital stay and return to work were found to be significantly better with arthroscopic repair [9, 11, 14]. This facilitated a transition of primary procedure from open procedure to one that is increasingly being performed arthroscopically [1, 2, 8, 9, 15–18]. Arthroscopic acromioplasty has a reported patient satisfaction rate of 67–92% from current literature [8, 9, 11, 12, 15–17]. There is currently no evidence to guide treatment in patients who continue to demonstrate impingement symptoms following arthroscopic decompression. The aim of this study is to prospectively assess outcomes of revision open subacromial decompression in patients who did not have a satisfactory benefit from a previous arthroscopic acromioplasty. 2. Methods Over a 48-month period, all patients presenting with impingement type symptoms underwent a through clinical examination and MRI. Patients with additional shoulder pathologies and rotator

    Abstract: Introduction: Acute intoxications become more and more a serious problem in developing countries. However, epidemiologic data are very scarce in these countries. Objective: To describe the characteristics of acute intoxications in two University Hospitals of Ouagadougou (Burkina Faso). Methods: All cases admitted to the emergency services of the two sole University Hospitals of Ouagadougou from July 1, 2006 to June 30, 2007, were included. We analysed the medical records for demographical and etiological characteristics of the acute poisoned-patients. Results: Acute poisoned-patients (436) represented 1.9% of the patients admitted to these services. The majority of acute poisoned-patients were pre-school children followed by young adults. Accidental intoxications (70.8%) were more common than intentional (28.9) and suicidal attempts (0.3%). Among poisoned-patients, female patients represented a great majority. Pharmaceuticals were the most common cause of acute intoxication, followed by chemicals, animals' toxins, food, alcohol and addictive drugs. Conclusion: Our study revealed that pharmaceuticals were the most common cause of acute intoxications. The great majority of poisoned-patients were young. Female patients were the major poisoned-patients. Most admissions in the emergency services due to acute intoxications resulted from accidental poisoning.

    International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2016, DOI: 10.4236/ijohns.2016.53019
    Abstract: Introduction: The complications of cervicofacial cellulitis are one of the most serious emergencies Oto-Rhino-Laryngology (ORL). These complications are still observed in our context despite the advent of antibiotics. The aim of our study was to describe the clinical presentation and management of patients admitted to our institution for complications of cervicofacial cellulitis. Patients and Methods: It came from a retrospective study in the ORL service, a department of Yalgado Ouédraogo Hospital of Ouagadougou, between January 2005 and December 2014, during which all patients with cervicofacial cellulitis complications were identified. Results: We collected over 10 years, 69 cases of complicated cellulitis, a frequency of 54.3% of cervicofacial cellulitis and 2.3% of all hospitalizations. The group included 33% women and 67% men to 29 years of average age. The non-steroidal anti-inflammatory isolated was the main factor contributing 59.4%. The front door was mainly dental 43.5% and pharyngeal 36.2%. The most frequent complications were mediastinitis thoracic dissemination 24.6%, sepsis 21.7% and spontaneous fistula 20.3% with orostome or pharyngostome. Medico-surgical treatment was associated with a reanimation in most cases. The outcome was favorable in 79.7% of cases. Mortality was 17.4%. Conclusion: The complications of cervicofacial cellulitis are frequent and often life-threatening. Their management is done in a multidisciplinary framework. The prevention and early treatment remain the pledge of their control.

    Abstract: Background: Hemorrhoidal disease is most frequently encountered in proctology affection; it is defined by signs or symptoms attributed to hemorrhoids. Its pathogenesis is based on old theories and vascular mechanical which are nevertheless based on the current therapeutic approach. General Aim of the Study: To study haemorrhoids’ pathology in order to improve its management. Methodology: A retrospective cross-sectional study was conducted over a period of two (2) years from 1 January 2012 to 31 December 2013. Data were collected from outpatients records in hepato-gastroenterology and digestive surgery services at “Polyclinique Notre Dame de la Paix” in Ouagadougou (2294 files). Results: 140 cases of haemorrhoids were recorded during our study period. The frequency was 6.1% of consultations. Males predominated with 75.71% of patients (sex ratio = 3.12). The average age was 39.58 years. Civil servants were most affected by this disease (60%). Rectal bleeding was the most common reason of consultation (52.14%). The crown shape was predominated (59%). The frequency of external haemorrhoids was the highest (65.71%) and stage 4 (40.79%) was the most represented. Anal fissure was the proctologic pathology, the most associated to haemorrhoids (17.14%). Medical treatment concerned 89.28% of patients with 69.6% of favorable short-term evolution. No instrumental treatment was performed. Surgical treatment consisted of 10.71% of patients and the technique used was the Milligan-Morgan performed under spinal anesthesia. The postoperative complications were mainly represented by anal intense pain and acute urinary retention. The healing period of wounds was on average 6 weeks. Conclusion: The hemorrhoid has often underestimated in our regions. The instrumental treatment is nonexistent and should take an important place; it must be an indication before surgery.
