Balanced Reciprocal Translocation t(X;1) in a Girl with Tall Stature and Primary Amenorrhea

AbstractChromosomal translocations constitute one of the most important, yet uncommon, causes of primary amenorrhea and gonadal dysgenesis. Although X-autosome translocations are frequently associated with streak gonads and clinical features of the Turner syndrome, the majority of X-autosome carriers may present with a variable phenotype, developmental delay, and recognizable X-linked syndrome ...

Quantification of Mean Vessel Density in Retinoblastoma and Its Correlation with Local Tumor Invasion and Patients Survival

  Background and Objectives: Retinoblastoma is the most common intraocular pediatric malignancy. Angiogenic factor expression such as VEGF (vascular endothelial growth factor) in retinoblastoma can be confirmatory angiogenic potential of this tumor.
