The objective of this study was to determine the epidemiological and diagnostic profile of chronic carriers of hepatitis B virus seen for gastroenterology consultations in Parakou, Republic of Benin. Patients and Methods: This was a cross-sectional and descriptive study with retrospective data collection. Patients seen for gastroenterology consultations from January 1, 2017 to June 30, 2021 at the Regional Teaching Hospital of Borgou/Alibori (CHUD-B/A) and having been diagnosed as chronic carriers of hepatitis B virus were included. A minimum initial assessment was required to be included. The minimum sample size was calculated with Schwartz formula. The variable of interest was the detection of HBsAg twice and at least 6 months apart. The other variables studied were sociodemographic, clinical and paraclinical data. The data collected were analyzed using SPSS 17 software. Results: A total of 2786 patients were seen for gastroenterology consultations, including 1126 (40.4%) HBsAg-positive patients. Among them, 417 patients met the inclusion criteria and were the subject of the present study. The average age of the patients was 34.8 ± 10.5 years. Two hundred and forty-seven patients (65.7%) were male, representing a sex ratio of 1.9. The discovery of positive HBsAg status was made during systematic screening in 231 patients (55.4%). Scarifications were noted in 373 patients (89.4%). Asthenia was reported in 184 patients (44.1%). Co-infections with human immunodeficiency virus, hepatitis C and D viruses were 0% (0 in 92), 2.8% (4 in 146) and 14.3% (2 in 146), respectively. During the initial assessment, 274 patients (65.7%) were sero-negative for chronic HBeAg infection, 21 (5%) had clinically significant fibrosis including 16 (3.8%) at the stage of cirrhosis and 7 patients (5.4%) had hepatocellular carcinoma. Conclusion: In Parakou, chronic hepatitis B virus infection is common and affects young people with a male predominance. Asthenia is a non-specific symptom and the most reported by the patients. Around 5 out of 100 patients are seen for consultations at the stage of complication. Emphasis must be placed on early detection and subsidy for pre-therapeutic assessment.展开更多

Methods: A retrospective and descriptive study was carried out at The National and University Teaching Hospital Hubert Koutoukou Maga (CNHU-HKM), of Cotonou in Benin from November 1st to December 31st. A review of CT scans skull was done for the subjects aged at least 16 years old. Anatomic variants of the sphenoid sinuses and adjacent structures have been investigated. Results: 225 CT scans of skull were analyzed. The sellar type was the most common type of pneumatization of sphenoid sinuses (74.7%). Pneumatization of anterior clinoid processes of greater and lesser wings of the sphenoid and of pterygoid processes was observed in 7.1%;4.6%;3.3% and 7.3%;respectively. Protrusion of carotid canals and optic canals, maxillary and vidian nerves were observed in 48.3%;13.1%;18% and 9.5%;respectively. Conclusion: Risky anatomic variants of the sphenoid sinuses and adjacent structures are also described by CT-scan among Beninese. Before any surgery and to avoid bad outcome, a precise approach of these risky anatomic variants must be carried out by using CT-scan.展开更多

Methods: A review of 225 CT scans skull was done for subjects aged at least 16 years old from November 1st to December 31st 2017. The pneumatization of adjacent structures of sphenoid sinuses and its relation with the protrusion of neurovascular structures surround the sinuses have been investigated. We used Fischer Exact test for comparison. The p value Results: Statistically significant associations were found between anterior clinoid process bilateral pneumatization and bilateral protrusion of carotid canal (p Conclusion: Compared to the literature, the prevalence of pneumatization of the adjacent structures of sphenoid sinuses was lower on Beninese than Caucasian and Asian. But there were the same correlations with the protrusion of neurovascular structures. In case of endonasal surgery of the sphenoid sinuses, surgeon should be aware of the high possibility the injury of optic nerves and internal carotid artery.展开更多
Sphenoid sinuses are carved into the body of the sphenoid bone. They are probably the most variably pneumatized structures of the skull.

They are probably the most variably pneumatized structures of the skull. They begin their pneumatization at the age of three and finished at adolescence. Several anatomic variants of sphenoid sinuses have been described in the literature. The agenesis of sphenoid sinuses in adults is very rarely found. We report two incidental cases of sphenoid sinuses agenesis discovered on CT scan in Benin, West Africa.展开更多
