In developed countries, this practice is common and sees the indications constantly reviewed;In sub-Saharan Africa, this surgical technique is popularized. The external pathways are morbid and not very functional. In our daily practice at the Yaounde General Hospital (YGH), this technique is still in its infancy. Gradually it’s entering our habits and sees its indications increases. Through this study, we are reporting readily available data from our experience. <strong>Objectives:</strong> The objective was to study the practice of endoscopic endonasal surgery in our setting. <strong>Patients and Method:</strong> This was a cross-sectional, descriptive, retrospective study. The site of study was the ear-nose and throat service of Yaounde General Hospital. The study was conducted from January 2013 to December 2020, for an 8 years basis. The sampling was consecutive. We included in this study all patients operated on for a nasal sinus disease by the endoscopic endonasal modality. We excluded patients with incomplete files, as well as those who had a complementary transfacial approach during the same operation. The data were collected on prepared questionnaire. Data analysis is done with ssps 23.0 software. <strong>Results:</strong> We recruited 30 cases, out of a total of 330 interventions carried out in our department. The prevalence of this surgery in our activity was 9%. Male and female had equal ratio of 50%. The most represented age group was 30 - 40 years (33.3%). All the patients had a facial sinus CT scan, we did not note any anatomical variant as risk. Two patients of our sample size had a history of sinus surgery, treated externally. Chronic maxillary sinusitis was the surgical indication in 36.7%, followed by Killian antro-choanal polyps in 13.3%, nasosinus polyposis in 13.3% and all performed under general anesthesia. The most performed procedure was unilateral mean meatotomy with 43.33% followed by bilateral mean meatotomy with 20%, ethmoidectomy 13.3%, bimeatotomy 10%. The admission lasted for 2 days. 100% of patients had a previous nasal tamponade at the end of the intervention. The tamponade was removed on the second postoperative day in 100% of patients. 16.7% of patients presented with complications of low abundance postoperative bleeding. All patients noted clinical improvement over the initial symptoms postoperatively. <strong>Conclusion:</strong> Endoscopic endonasal surgery is experiencing slow but certain progress in our daily practice. The operated patients are young, chronic maxillary sinusitis is the main indication, the most performed procedure is the unilateral mean meatotomy. The operation goes uneventful with satisfactory prognosis. A study with a larger sample is necessary in order to refine our results. The practice remains limited by the technical platform, which needs to be strengthened, in order to optimize the practice.展开更多

However, it suffers enormous damage caused by a bruchidae beetle, Caryedon serratus. This lust rests on its richness in proteins, calories and the absence of major constraints for its production. Losses recorded can reach 83% for a period of 4 months of storage. To counter this damage, several authors have looked for alternative methods to the use of synthetic insecticides, often harmful to animal populations and the environment. In this logic, we tested the biological impact of a leaf-based formulation of plants indigenous to Senegal (Crateva religiosa) on the external forms of C. serratus. In this study, analysis of the biological parameters of strain C. serratus showed low adult mortality of C. serratus. On the other hand, the extract affects the viability of eggs and larvae and fertility is reduced. The effect of the C. religiosa plant also results in reduced fertility of surviving females and a sex ratio in favor of the males causing a risk of decreasing population growth. On the other hand, there is an extension of the total development time.展开更多

Material and method: Over a period of 15 months (April 1, 2014 to June 30, 2015), all the records of cirrhotic patients who followed up on an outpatient or inpatient basis in the hepato-gastroenterology department of the Aristide Le Dantec Hospital were collected. The data collected were as follows: age, sex, Child-Pugh severity score, etiology of cirrhosis, indication for endoscopy and endoscopic lesions observed. Results: Data were analyzed from 82 patient records with a mean age of 43 years (range 16 and 79 years) and a sex ratio of 1.4 (54 males). Cirrhosis was classified as Child-Pugh B in 47% of cases and Child-Pugh C in 35% of cases. The etiology was viral B in 75 patients (91.5%), B-D co-infection in 2 cases, and alcoholic in 1 case. The indication for oeso-gastroduodenal endoscopy was a systematic search for signs of portal hypertension in 66 cases (80.4%), upper gastrointestinal haemorrhage in 11 cases (13.4%) and epigastralgia in 6.2% of cases. Endoscopic lesions unrelated to portal hypertension were observed in 61 patients (74.4%). Peptic ulcer was present in 26 patients (31.7%), and congestive gastrobulbitis was observed in 38 patients (46.3%) and erosive gastrobulbitis in 32 patients (39%). Of the 43 upper GI endoscopies with biopsies, Helicobacter pylori was found at histology in 17 cases (39.5%). Eighteen patients (21.9%) had esophageal candidiasis. In multivariate analysis, there was no association between no portal hypertension lesions and the severity of cirrhosis. Conclusion:Upper gastro intestinal lesions unrelated to hypertension were present in 3/4 of cirrhotic patients. Peptic ulcer disease and congestive and erosive gastrobulbitis were the most frequently observed lesions. There was no significant association between non-PTH-related lesions and the severity of cirrhosis.展开更多
