The care of children with Wilm’s tumor in sub-Saharan Africa is compromised due to resource deficiencies that range from inadequate healthcare budgets to paucity of appropriately trained personnel. Childhood Wilms tumor is surging as an important paediatric problem in developing and sub-Saharan Africa countries. The objective of the study is to establish an understanding on the treatment challenges and outcomes of Wilm’s tumor in South West Ethiopia. Results: Forty-three Wilm’s tumor patients who were admitted from January 2017 to December 2021 were included in the study. The most frequent presentation was painless abdominal swelling in 40 (93%) patients. Fourteen patients (32.6%) were hypertensive at the time of diagnosis and the other 13 (30.2%) were normal. In abdominal examination, 31 (72.1%) patients had abdominal mass not crossing the midline and 12 (27.9%) had mass crossing the midline. After multimodal treatment, 37.5% had improvement, 11.6% came back with relapse. Most patients (41.7%) abandoned treatment and 9.3% of the cohort died in the course of treatment. Conclusion: The outcomes in the treatment of Wilms Tumor have been found to be poor in this review. The main reason for poor outcome has been not receiving adequate chemotherapy after surgery. Doses of chemotherapy received after surgery significantly affected treatment outcomes (p = 0.026).展开更多

Its discovery usually indicates a serious eye disease especially in children. Objective: To determine epidemiological and diagnostic aspects of childhood proptosis in Lome (Togo). Methods: Retrospective cross-sectional study conducted from June 2010 to May 2020, which is 10 years, in the ophthalmology department of CHU-campus of Lome. Files of patients between the age of 0 and 15 who presented a proptosis during the study period were taken into account in the study. Patients with a false proptosis or incomplete records during the study period were not taken into account in the study. Results: The study considered 42 children with an age average of 7.63 years ± 4.96 [4 days;15 years] and a sex-ratio of 1.33. The frequency of proptosis was 0.5% with an average progression of 383.7 days before the first consultation. The proptosis was unilateral in 80.95% of cases. The orbito-cerebral CT scan was done in 47.62% of cases. The proptosis in these patients was predominantly of grade 3 in 45% of cases. The tumor pathologies were at the forefront in 35.71%, dominated by retinoblastoma, and followed by infectious and inflammatory diseases in 14.29%. Conclusion: Childhood proptosis is rare and often indicative of infectious and tumor pathologies in our context. Its diagnosis is delayed, which shows the importance of an early and effective diagnosis. .展开更多

Methods Measurement of function of hematopoietic organ, liver, kidney and heart immunology and thyroid grand and detection of level of electric elements in serum and metabolism of calcium and phosphate in 77 childhood cases with malignant tumors. Results The average period of cease of anticarcinogenic treatment was 3 years(2 months to 10 years). Most of indicators of function were showed in normal limit for hematopoietic, liver, kidney, heart, immunology and thyroid grand as well as level of electric elements in serum in 77childhood cases with malignant tumors. All the results suggested that there were no obvious damage in function of vital viscera and no plain differences among various kinds of tumors. Conclusion The current scheme of anticarcinogenic treatment performed in our center showed safety and reliability without obvious damage in function of vital viscera as well. It is needed that further prolonged the following time, expended the samples and selected more sensitive laboratory indicators.展开更多
