Medical devices used for functional or esthetic purposes improve health and quality of life; however, they are not risk-free. Anaplastic large-cell lymphoma (ALCL), associated with breast implants, is a well-known and recognized distinct lymphoma entity. More recently, additional lymphomas have been reported in relation to prosthesis other than breast implants, as these allow the pericyte to develop into a clone that undergoes a maturation process, progressing toward full malignancy.

Introduction: Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare form of non-Hodgkin T-cell lymphoma associated with breast reconstruction post-mastectomy or cosmetic-additive mammoplasty. The increasing use of implants for cosmetic purposes is expected to lead to an increase in BIA-ALCL cases. This study investigated the main characteristics of the disease and the factors predicting BIA-ALCL onset in patients with and without an implant replacement.

  • Congenital hydrocephalus (CH) is a diverse set of birth defects with varying prevalence, and this study aimed to analyze the early neonatal case fatality rate (CFR) and total birth prevalence (BPR) among newborns with CH using data from 25 international registries from 2000 to 2014.
  • The study found that the early neonatal CFR was 5.9 per 100 liveborn CH cases, with syndromic cases having a significantly higher CFR than non-syndromic cases (10.4% vs. 4.4%).
  • Although there were substantial differences in CFR and BPR across registries, higher CFR often correlated with higher BPR; however, most

Variation in cancer incidence between countries and groups of countries has been well studied. However cancer incidence is linked to risk factors that may vary within countries, and may subsist in localized geographic areas. In this study we investigated between- and within-country variation in the incidence of all cancers combined for countries belonging to the Group for Cancer Epidemiology and Registration in Latin Language Countries (GRELL).
