Introduction: The parotid tumors are benign or malignant, primary or secondary neoformations developed at the expense of the parotid gland. The aim of the present study was to describe the indications and results of parotidectomies in the ENT department of the Idrissa Pouye General Hospital in Dakar. Patients & Methods: We conducted a retrospective study between January 1, 2004 and December 31, 2012, including all patients who had been consulted for a parotid tumor with or without histological evidence collected in the otolaryngology and anatomy-pathology department of the Idrissa Pouye General Hospital in Dakar. Results: We collected 31 patient files. The mean age was 47.45 years, with extremes of 16 and 74 years. Females predominated, with a sex ratio of 0.82. Swelling of the parotid region was the main reason for consultation in 100% of cases. Parotidectomy was the most frequently performed procedure, accounting for 41.93%. Benign tumors accounted for 72% of cases, the majority being pleomorphic adenomas (50%). The outcome was favorable in 67.74% of cases. Conclusion: Management of parotid tumors at HOGIP would be improved by informing and educating patients to consult early, and by upgrading the technical platform.

Goiters account for a very high prevalence disease. In Senegal, surgery is a very important part of the management. Our aim is to determine indications and results of thyroidectomies at the regional hospital of St. Louis. Patient and Method: We conducted a descriptive retrospective study over a period of 6 years on 81 records. All patients who underwent thyroidectomy during the study period were included. Computer software EPI INFO and Excel were used for collection and processing of data. Results: The average age of our patients was 40 years with a sex ratio at 0.05. The determination of TSH found 88.9% in euthyroid, 1.2% in hypothyroidism and 9.9% in hyperthyroidism. Thyroid ultrasound was performed in 97.5% of patients. Surgically, gestures performed were divided between the lobo-isthmectomies (43.1%), subtotal thyroidectomy (9.8%), total thyroidectomy (46.91%). The postoperative course was uneventful in all patients. The histology was benign in 88.9% of surgical specimens and found adenocarcinoma in 11.1%. Conclusion: Our study confirms the predominance of female thyroid pathology. The thyroidectomy which is getting better codified occupies an important place in the management. It offers the advantage around the problem of therapeutic non-compliance and also stockouts in our region.

Background and Objective: The outcome of locally advanced and metastatic urothelial carcinoma LA/mUC has improved over the past years with a plethora of new treatments and the approval of immune checkpoint inhibitors (ICIs), antibody-drug conjugates, and targeted agents, to identify locally advanced metastatic urothelial carcinoma’s current management practices in Lebanon and the implication of the ongoing economic crisis on the medical practice. Methods: An online questionnaire was used to survey ten Lebanese oncologists from six different hospitals, between July 5 and July 11, 2022, requesting information pertaining to their current clinical practice in the pharmacological treatment of locally advanced metastatic urothelial carcinoma. Key Findings: Cisplatin-based chemotherapy was the most frequently reported initial treatment of locally advanced metastatic urothelial carcinoma. Participants reported using immune checkpoint inhibitors in platinum-ineligible patients and those with PDL1 positive tumors. Also, they would not consider the concomitant use of immunotherapy and chemotherapy in the first-line setting. Participants believed that avelumab maintenance is effective in the absence of progression after first-line platinum-based chemotherapy;they would consider initiating it 2 - 10 weeks after completion of chemotherapy. Conclusions and Clinical Implications: After comparing with current international guidelines, this study shows that Lebanese oncologists follow international guidelines and have deep knowledge of recent clinical trials for the management of locally advanced metastatic urothelial carcinoma, regardless of economic crisis challenges.

Many data mining applications have a large amount of data but labeling data is usually difficult, expensive, or time consuming, as it requires human experts for annotation. Semi-supervised learning addresses this problem by using unlabeled data together with labeled data in the training process. Co-Training is a popular semi-supervised learning algorithm that has the assumptions that each example is represented by multiple sets of features （views） and these views are sufficient for learning and independent given the class. However, these assumptions axe strong and are not satisfied in many real-world domains. In this paper, a single-view variant of Co-Training, called Co-Training by Committee （CoBC） is proposed, in which an ensemble of diverse classifiers is used instead of redundant and independent views. We introduce a new labeling confidence measure for unlabeled examples based on estimating the local accuracy of the committee members on its neighborhood. Then we introduce two new learning algorithms, QBC-then-CoBC and QBC-with-CoBC, which combine the merits of committee-based semi-supervised learning and active learning. The random subspace method is applied on both C4.5 decision trees and 1-nearest neighbor classifiers to construct the diverse ensembles used for semi-supervised learning and active learning. Experiments show that these two combinations can outperform other non committee-based ones.

The majority of spatial data reveal some degree of spatial dependence. The term “spatial dependence” refers to the tendency for phenomena to be more similar when they occur close together than when they occur far apart in space. This property is ignored in machine learning (ML) for spatial domains of application. Most classical machine learning algorithms are generally inappropriate unless modified in some way to account for it. In this study, we proposed an approach that aimed to improve a ML model to detect the dependence without incorporating any spatial features in the learning process. To detect this dependence while also improving performance, a hybrid model was used based on two representative algorithms. In addition, cross-validation method was used to make the model stable. Furthermore, global moran’s I and local moran were used to capture the spatial dependence in the residuals. The results show that the HM has significant with a R2 of 99.91% performance compared to RBFNN and RF that have 74.22% and 82.26% as R2 respectively. With lower errors, the HM was able to achieve an average test error of 0.033% and a positive global moran’s of 0.12. We concluded that as the R2 value increases, the models become weaker in terms of capturing the dependence.
