Immunohistochemical Expression of Ki67 and p53 in Wilms Tumor and Its Relationship with Tumor Histology and Stage at Presentation.

Aim. Evaluate tumor proliferation marker (Ki67) and p53 tumor suppressor marker in Wilms tumor and correlate with histology, anaplasia, and staging. Design.

Efficacy of the seven feature, fifteen point histological scoring system and CD56 in interpretation of liver biopsies in persistent neonatal cholestasis: a five-year study.

Context: Neonatal cholestasis (NC) lasting more than 2 weeks affects one in 2500 live births. Extrahepatic biliary atresia (EHBA) and idiopathic neonatal hepatitis account for about 70% of all cases of NC. Differentiating these two conditions is important as patient management is very different for both the conditions.

Calretinin immunohistochemistry: A new cost-effective and easy method for diagnosis of Hirschsprung's disease.

Aim: To evaluate the efficacy of calretinin immunostaining in diagnosing Hirschsprung's disease (HD).

Materials And Methods: Sixty cases were studied over a period of 1 year (July 2010-June 2011). There were 36 full-thickness biopsies and 24 resected specimens.
