Purpose: Congenital mesoblastic nephroma (CMN) is a mesenchymal renal tumor of the newborn and young infant. This tumor is generally non-aggressive and amenable to surgical removal. Few studies are available in Africa about the treatment of CMN. The aim of this retrospective study was to evaluate the treatment of CMN in the pediatric oncology unit of teaching hospital Gabriel Toure in Bamako-Mali.
Patients and method: The study was performed retrospectively from 01 January 2005 to 31 December 2016 (duration 11 years), in the pediatric-oncology unit of Gabriel Touré Teaching Hospital. Were included, patients with histologically proven CMN. The uretero-nephrectomy was indicated for all included patients. Patients with significant tumor volume at abdominal CT-scan and those with no staging at surgery with imprecise histologic stage, received neoadjuvant and adjuvant chemotherapy, respectively.
Result:From 2005/01/01 to 2016/12/31 eight cases of CMN were included in the study. CMN accounted for 3% of renal tumors. The median age of patient was 4.5 months (1 month-6 months) with a sex ratio of 0.33 (M = 2, F = 6). Abdominal mass was the most common physical sign (n = 7; 87%). The CT scan was performed in five patients (62%). There was no difference in laterality (right kidney, n = 4, left kidney, n = 4).
Three patients received neoadjuvant chemotherapy (37%). Seventy-two percent of patients received initial nephro-ureterectomy. The histology confirmed CMN in all patients (n = 8, 100%). All patients had the classic histological form (n = 8; 100%). Stage 1 (n = 4; 50%), stage 2 (n = 2; 25%), unspecified (n = 2; 25%). Two patients received adjuvant chemotherapy (25%). Overall survival was 100% with a median follow-up of 8 years (6 -10 years).
Conclusion: Multidisciplinary collaboration is the key of therapeutic success of CMN.Read More

In the last three decades, the constantly increasing need for therapies, efficiently preventing and/or treating human diseases, has raised the interest in Regenerative Medicine (RM). RM is based on employing mesenchymal stem cells (MSCs), that showed to have great proliferation, self-renewal and multi-lineage differentiation potential, in vitro as well as in vivo. The opportunity of an accessible, painless and low-cost reservoir of MSCs constitutes the first important step of a successful regenerative therapy to include in the current clinical practice. Oral cavity has recently demonstrated to contain different MSCs niches: dental pulp from permanent and deciduous teeth, periodontal ligament, dental follicle, apical papilla and mucosa. MSCs from dental pulp of deciduous teeth, naturally lost in pediatric age, and the oral mucosa have shown to be easily harvested and to have a promising regenerative potential. Thus, the aim of the paper is to review the potentialities of human exfoliated deciduous teeth stem cells (SHEDs) and oral mucosa stem cells (OMSCs) in RM, with the purpose of their use as accessible source of MSCs for the future of pediatric patient.Read More

Introduction: Childhood cancer is relatively uncommon and the European age-standardized rate was 164 new case per million per year among 0 to 15 years old children (95% CI 158-170). We analyzed data collected in the Mod. 1.01 of the AIEOP (Association Italian Pediatric Hematology-Oncology) over 25 years (1990-2014) about patients with malignant disease diagnosed in 90 towns of the “Ground of fires” (56 in Napoli and 34 in Caserta province).
Methods: Thanks to the wide monitored population we defined 5 time trends: 1990-94; 1995-99; 2000-04; 2005-09; and 2010-14. We calculated the ratio between observed cases (O) and expected (E) numbers of cases among the children from “Terra dei fuochi”.
Results: 2037 cancer patients (0-15 years) were registered in the AIEOP database: 1144 males (56.1%) and 893 females (43.8%).
Conclusions: It is note-worthy to underline that our cases needed to be integrated with the Hospital Informative System and Register of births, marriage and deaths to have a better collection of observed cases. This is a limit of our study. The data analysis do not show significant differences in number of observed cases and type of diseases respect to our previous epidemiological study on cancer cases registered in Campania.Read More
