Coriocarcinoma cervical metastásico en mujer de 45 años con antecedente de HSIL / Metastatic choriocarcinoma in a 45-year-old woman with a previous high-grade squamous intraepithelial lesion

El coriocarcinoma es una neoplasia epitelial rara, perteneciente al grupo de las enfermedades trofoblásticas gestacionales. Se caracteriza por la presencia de células del sincitotrofoblasto, citotrofoblasto y trofoblasto intermedio, que pueden presentar invasión tisular y vascular. Resumen Mujer de 45 años, última gestación 10 años atrás. Recibe tratamiento de lesión escamosa intraepitelial de alto grado (HSIL). Tras conización, presenta sangrados irregulares. Descartada la posibilidad de enfermedad cervical residual o patología de origen endometrial, nos orientamos hacia el diagnóstico de coriocarcinoma cuando la paciente presenta hemoptisis por metástasis pulmonares. Se realiza revisión de los criterios diagnósticos, manifestaciones clínicas y pronóstico (AU)

Choriocarcinoma is a rare epithelioid neoplasm belonging to the group of gestational trophoblastic disease. The histologic feature is syncytiotrophoblastic, cytotrophoblastic and intermediate trophoblastic cells which can permeate among the myometrial fibers and vessels. AbstractWe report a case of choriocarcinoma diagnosed in a 45-year-old woman 10 years after her last pregnancy. She was treated for a high-grade squamous intraepithelial lesion (HSIL). After surgical treatment, she showed irregular vaginal bleeding. Once residual cervical disease and endometrial disease had been excluded, we suspected metastatic gestational trophoblastic disease when the patient showed hemoptysis due to pulmonary metastasis. We review the diagnostic criteria, clinical expression and prognosis of this entity (AU)

Behenamidopropyl Dimethylamine: unique behaviour in solution and in hair care formulations.

SYNOPSIS: The rise of ecological awareness among consumers and industry has impacted the cationic surfactants market. The most used cationic surfactants present some drawbacks in this sense. Therefore, new molecules are being studied and developed which fulfil eco-toxicological requirements without losing performance. One of these surfactants is Behenamidopropyl Dimethylamine (BAPDMA). This biodegradable amidoamine, which converts into a cationic surfactant at acidic pH, shows outstanding water solubility, despite its very long alkyl chain. Its behaviour in solution has been exhaustively studied. The conditioning performance of this product is superior to that of commonly used cationic surfactants, providing a superior sensorial profile and improved combing force reductions on hair. Moreover, other applications for this product in the non-ionic form have been studied, such as conditioning agent in 2 in 1 shampoos, where it also shows colour protection effects, and as gelling agent in hair colouration creams. This multifunctional and high performance profile, together with an improved biodegradation and aquatic toxicity compared with currently used cationic surfactants, make this product a very interesting eco-friendly alternative for the hair care market.
