Surgical Treatment of Nephroblastoma in a 4-Year Male Child: A Case Report and Literature Review

引用

Case Reports in Clinical Medicine 2024年第2期13卷 43-51页

作者： Alexander Kofi egote Samuel Kolonziah Blay Constance Amuzuah egote Cardinal Kofi Newton Albert Afriyie Akowuah emmanuel Nana Bosoma Urology Unit Sunyani Teaching Hospital Sunyani Ghana

Herein we report a patient with nephroblastoma which was successfully removed at the Sunyani Teaching Hospital CJ Oppong theatre in Ghana in sub-Saharan Africa by extended below umbilical incision. Our patient had a family history of Wilms tumour predisposing him to the disease. His main symptoms were haematuria and abdominal mass which was noticed later. examination and investigation were suggestive of a late-stage unilateral Nephroblastoma resulting in the need for nephrectomy. To reduce the need for such radical surgeries among children at an early stage, there is the need for early screening of children for Wilms tumours especially, those with family predisposition as in our case study. The case report presented here constitutes a rare case of nephroblastoma in the literature.

The authors report a case of deficient sensory neuropathy secondary to vitamin B12 deficiency, diagnosed in the neurology department of the Sino-Central African Friendship University Hospital in Bangui. The diagnosis was made possible by electroneuromyography which showed subclinical neurological damage associated with hematological damage (anemia). Through this observation, we recall the diagnostic criteria of the disease in a context of difficult medical practice. .

Usefulness of the Surgical Apgar Score to Predict the Occurrence of Major Complications in the early Post-Operative Period of Major Surgeries: experience of Two Second-Category Hospitals in Cameroon

引用

Open Journal of Anesthesiology 2024年第3期14卷 51-65页

作者： Charles emmanuel Toussaint Binam Bikoi Francis Ateba Ndongo Serge Vivier Nga Nomo Édouard Léa Mekoui Ze Fidèle Binam Department of Anesthesia and Intensive Care University of Ebolowa Ebolowa Cameroon Yaounde Mother and Child Center Chantal Biya Foundation University of Garoua Garoua Cameroon Department of Anesthesia and Intensive Care Catholic University of Central Africa Yaounde Cameroon

Objective: The Surgical Apgar Score (SAS) is a tool for intraoperative stratification of the risk of serious complications in the early postoperative period. It varies from 0 to 10 points divided into three risk categories (0 to 4 high, 5 to 7 moderate, 8 to 10 low). The aim of the study was to evaluate its relevance in predicting the appearance of these complications. Material and methods: This descriptive and analytical study was carried out at the “Laquintinie” Hospital in Douala and at the Central Hospital in Yaounde, Cameroon. The main data were collected on a population of patients over 18 years old and recorded on a survey form. They consisted of variables of main interest and exposure variables. Univariate and multivariate statistical analysis using top-down logistic regression models made it possible to evaluate the association of each variable of main interest and each exposure variable. The association was significant at P Results: Of the 88 patients studied, the SAS was 3 hours. In multivariate, this link persisted only and strongly for the SAS OR (IC) 0.1 (0.1 - 0.2) and p = 000. Conclusion: The study found a specific and powerful link between the SAS score e occurrence of complications in the early postoperative period, in favor of its relevance in predicting them.

Jigsaw-Sketch: a fast and accurate algorithm for finding top-k elephant flows in high-speed networks

引用

Science China(Information Sciences) 2024年第4期67卷 113-130页

作者： Boyu ZHANG He HUANG Yu-e SUN Yang DU Dan WANG School of Computer Science and Technology Soochow University School of Rail Transportation Soochow University

Finding top-k elephant flows in high-speed networks is one of the most fundamental network measurement tasks. It is more challenging than per-flow size estimation since the IDs and sizes of top-k flows must be tracked simultaneously. Most existing studies only record the IDs of a small number of elephant flows to fit their estimators in the extremely limited high-speed on-chip memory. However, these solutions need too many memory accesses when a packet arrives to track the elephant flows with high accuracy, which limits their practicability. Therefore, this paper proposes Jigsaw-Sketch, a new algorithm to find the top-k elephant flows with much fewer memory accesses while achieving high memory efficiency and accuracy. In this design, we propose a novel two-stage jigsaw storage scheme, which can capture the candidate top-k flows from massive network steams efficiently, and further find the top-k elephant flows with high memory efficiency and only a few memory accesses for each packet. extensive experimental results based on real network traces show that Jigsaw-Sketch improves the packet processing throughput by at least 86%, while achieving smaller memory footprints and higher accuracy compared to the SOTA.

目的分析经皮冠状动脉介入(PCI)治疗的急性冠状动脉综合征(ACS)患者早期不同联合降血脂策略的疗效。方法选取2018年1月至2022年6月大连医科大学附属第一医院诊断为ACS并行PCI治疗的患者,根据患者出院时降血脂方案,分为A组(他汀类药物+依折麦布)、B组(他汀类药物+依洛尤单抗)和C组(他汀类药物+依折麦布+依洛尤单抗),各73例。比较3组患者基线及1、6个月随访时低密度脂蛋白胆固醇(LDL-C)和其他血脂指标水平变化。结果在1、6个月随访时,B、C组LDL-C较基线下降幅度显著大于A组,LDL-C0.05);3组间三酰甘油、载脂蛋白A1水平比较差异均无统计学意义(均P>0.05)。结论他汀类药物联合应用依洛尤单抗可快速降低ACS行PCI患者血脂,增加LDL-C达标率,但是在他汀类药物联合依洛尤单抗基础上再联合依折麦布降低LDL-C的效果并不优于他汀类药物联合依洛尤单抗。
