Background Extracranial Germ cell tumors (GCT) are a rare and a heterogeneous group of pediatric cancers but highly curable. Aim We aimed to review management, outcome and prognostic factors that influence overall survival (OS) in a pediatric Tunisian oncologic unit. Methods We retrospectively evaluated between January 1998 and December 2012, 33 patients affected by extracranial germ cell tumors and treated according to TGM95 protocol established by the SFOPin a pediatric Tunisian oncologic unit. Results Patients had a mean age of 57 months (ranges: 1 day-13 years). There were 19 girls and 14 boys. Primary sites included 12 sacrococcygeal, 11 ovarian, 6 testicular, 3retro peritoneal and 1 mediastinal site. After a mean follow up of 26.1 months (ranges: 0-96 months), OSat 2 years and 5 years were respectively 82% and 75%. Event-free survival were respectively 79% at 2 years and 74% at 5 years. Various prognostic factors have been studied according to Kaplan-Meier. Univariate analyses identified significant factors which influence strongly OS: the stage (p=0.04), the completeness of surgery (p<0.001) and the relapse (p = 0, 0001). A multivariate study showed that only the quality of resection and the clinical stage remained strong significant prognostic factors (p=0,021) for 5-year OS. Conclusion Disease stage, completeness of surgery and relapse have been established as the most powerful prognostic parameter in our analysis. The improvement of survival of patients affected by extracranial germ cell tumors in Tunisia is a real achievement mainly due to the success of salvage treatments.

Background: Cutaneous melanoma is one of the most invasive and lethal skin malignant tumors. Compared to primary melanoma, metastatic melanoma (MM) presents poorer treatment outcomes and a higher mortality rate. The tumor microenvironment (TME) plays a critical role in MM progression and immunotherapy resistance.

Background: We aim to identify risk factors contributing to extended rehospitalizations in patients diagnosed with postpartum endometritis requiring intravenous antibiotics.
Methods: This retrospective cohort study examined postpartum endometritis patients readmitted for treatment from 2014 to 2022, comparing short (≤ 48 h) and prolonged hospitalization (> 48 h). Data included patient demographics, medical history, presentation parameters, vaginal examination findings, sonographic data, laboratory results, and details of the current labor to create a scoring system predicting prolonged hospitalization risk.

Objectives: Neonatal necrotizing enterocolitis (NEC) is a common intestinal disease that threatens the lives of newborns and is characterized by ischemic necrosis of the small intestine and colon. As early diagnosis of NEC improves prognosis, the identification of new or complementary biomarkers is of great importance. In this study, we evaluate the diagnostic value of CCL3 in NEC and compare its effectiveness with other commonly used biomarkers, such as procalcitonin (PCT) and C-reactive protein (CRP).
