Spindle Cell Rhabdomyosarcoma of the Inguinal Region Mimicking a Complicated Hernia in the Adult-An Unexpected Finding.

Rhabdomyosarcoma is a rare tumor that is diagnosed mostly in children and adolescents, rarely in adults, representing 2-5% of all soft tissue sarcomas. It has four subtypes that are recognized: embryonal (50%), alveolar (20%), pleomorphic (20%), and spindle cell/sclerosing (10%). The diagnosis of rhabdomyosarcoma is based on the histological detection of rhabdomyoblasts and the expression of muscle-related biomarkers.

Acylhydrazones and Their Biological Activity: A Review.

Due to the structure of acylhydrazones both by the pharmacophore -CO-NH-N= group and by the different substituents present in the molecules of compounds of this class, various pharmacological activities were reported, including antitumor, antimicrobial, antiviral, antiparasitic, anti-inflammatory, immunomodulatory, antiedematous, antiglaucomatous, antidiabetic, antioxidant, and actions on the central nervous system and on the cardiovascular system. This fragment is found in the structure of several drugs used in the therapy of some diseases that are at the top of public health problems, like microbial infections and cardiovascular diseases. Moreover, the acylhydrazone moiety is present in the structure of some compounds with possible applications in the treatment of other different pathologies, such as schizophrenia, Parkinson's disease, Alzheimer's disease, and Huntington's disease.

Histopathological elements analyzed in dynamics in mechanical bowel obstructions - experimental study on laboratory animals.

Bowel obstruction is a syndrome that produces important alterations to the digestive tract, both macroscopically and microscopically. We conducted an experimental study using rats, Wistar strain, as subjects, dividing them into three groups. The group A consisted of six rats and served as control group, in the first day of the experiment a surgical procedure being performed to resect a small bowel and a colic segment to be analyzed microscopically afterwards.

The importance of screening and prenatal diagnosis in the identification of the numerical chromosomal abnormalities.

Background And Aims: The obstetric care of a pregnancy, as it is practiced today, includes non-invasive screening approaches as well as invasive procedures for the definitive prenatal diagnosis of fetal disorders correlations between indications for prenatal cytogenetic diagnosis and results of the chromosomal analysis made upon fetal cells. The aim of our study was to evaluate the correlations between the screening test results and results of chromosomal analysis on fetal cells.

Methods: Amniotic fluid samples from 1159 pregnant women were studied with the rapid FISH method and the cytogenetic analysis (karyotype).
