Introduction: Acute appendicitis represents an urgent surgical condition, requiring the removal of the vermiform appendix. Laparoscopy is the standard surgical approach. This study aimed to outline the epidemiological, clinical, therapeutic, and outcome characteristics of patients undergoing laparoscopic surgery for acute appendicitis. Patients and Methods: A descriptive, retrospective analysis was carried out in the Emergency and Digestive Surgery departments of the University Hospital Center of Brazzaville, spanning two years from January 1, 2021, to December 31, 2022. The study included all patients who underwent laparoscopic surgery for non-complicated acute appendicitis. results: The study included 12 cases of non-complicated acute appendicitis treated with urgent laparoscopy. The mean age of the patients was 37 ± 8.9 years, with a sex ratio of 0.7. The predominant symptom leading to consultation was pain in the right iliac fossa, with an average time to consultation of 6.4 ± 5.7 hours. Patient histories included diabetes in one case, obesity in two cases, and one case of prior abdominoplasty. During surgery, a phlegmonous appendix was observed in nine patients. The average duration of hospital stay was 3.6 ± 1.3 days, with all patients experiencing uncomplicated recoveries. Conclusion: The practice of emergency laparoscopic appendectomy is still relatively infrequent in our setting and presents an ongoing challenge.

Introduction: Hemorrhoidal disease is a common pathology and its surgical treatment is based, among other things, on pedicular resection after failure of medical and instrumental treatment. The aim of this study is to analyze the epidemiological, clinical, therapeutic and evolving aspects of hemorrhoidal disease at the stage of surgical treatment at the University Hospital Center of Brazzaville. Patients and Methods: We conducted a retrospective and descriptive study carried out from January 2020 to December 2021, a 24 months period, in the Digestive surgery department of the University Hospital Center of Brazzaville. It concerned patients who underwent a surgical procedure for hemorrhoidal disease. results: 21 cases were collected, representing a hospital frequency of 2.3%, with a sex ratio of 4.3 in favor of men. The average age of patients was 42.2 ± 11.9 years. The symptoms were mainly proctalgia, mass sensation and rectal bleeding. We recorded five cases (19.1%) of hemorrhoidal thrombosis and 16 cases (80.9%) of hemorrhoidal prolapse including 12 cases requiring manual integration (Goligher grade III) and four irreducible permanent cases (Goligher grade IV). The Grade III prolapse was associated with a polyp in one patient and with posterior anal fissure in another patient. Out of the 21 patients, 14 underwent a tripedicular hemorrhoidectomy according to Milligan and Morgan. Two patients underwent mono- and bipedicular hemorrhoidectomy with resection of associated lesions and five patients underwent emergency thrombectomy. The outcome was favorable for all our patients. The average length of hospital stay was 1.5 ± 2.1 days. Conclusion: In the event of failure of medical and instrumental treatment, the hemorrhoidal cure according to Milligan and Morgan is the surgical treatment of reference for hemorrhoidal disease at the University Hospital Center of Brazzaville.

Field data from the Lower Yellow river (LYr) covering a period of ten consecutive years are used to test a mathematical model for one dimensional sediment transport by unsteady flow developed previously by the writers. Data of the first year of the said period, i.e., 1976, are used to calibrate the model and those of the remaining years to verify it. Items investigated include discharge, water stage, rate of transport of suspended sediment and riverbed erosion/deposition. Comparisons between computed and observed data indicate that the proposed model may well simulate sediment transport in the LYr under conditions of unsteady flow with sufficient accuracy.

Background: Trauma is the main reason for consultation in the emergency unit. They deserve particular attention in the Congo where road accidents and violence of all kinds are increasingly observed. Methods: This study who carried out in the surgical emergencies at the University Hospital of Brazzaville, aims to analyze the epidemiological and etiological aspects, the anatomical lesions encountered;to describe their management, as well as to evaluate the induced mortality while emphasizing their place in all surgical emergencies. The prospective and analytical study included 2127 patients admitted to a traumatic emergency unit from January 1 to June 30, 2018. Medical records served as data sources. The measure of trauma severity was determined using Champion’s Trauma Score. The epidemiological, clinical and therapeutic parameters were studied. results: The population most affected was adolescents and young adults (mean age, 27.3 years) with a male predominance: 1318 men (i.e. 61.9%) for 809 women (i.e. 38.1%). road accidents (n = 819, or 38.5%) were the main cause of injuries, followed by violence (n = 702, or 33%) and falls (27.3%). The skull, limbs, thorax and abdomen are the main targets. The most observed lesions were limb fractures (n = 344, i.e. 16.1%), intracranial hematomas and contusions (n = 315, i.e. 14.8%), thoracic and abdominal wounds (n = 28, i.e. 1.3%). Mortality was evaluated at 0.6%, and was correlated with the severity of the lesions and the type of trauma. Conclusion: Trauma is very common in emergency consultations in Congo, with a hospital frequency of 75.1% of all emergencies. Preventive actions are essential to reduce their frequency.

1 IntroductionThe recent significant advances in the molecular electronics show that the molecular device is a good candidate with great potential as the successor to the silicon-based semi-conductors. After the successful experimental work made by reed et al. in which the single benzene molecule acts as the core of the molecular device, many experimental and theoretical investiga
