The Retinoblastoma Gene

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Area of Science:

Pediatric Nephrology
Diagnostic Imaging
Renal Pathology

Background:

A 6-year-old female presented with respiratory distress, progressing to respiratory failure requiring intubation.
The patient subsequently developed hypertensive crisis, hyponatremic hypochloremic metabolic acidosis, and acute kidney injury.

Observation:

Renal ultrasound revealed a lobulated, isoechoic to hyperechoic mass-like lesion in the right kidney with increased vascularity.
Further evaluation included Magnetic Resonance Imaging (MRI), Dimercaptosuccinic Acid (DMSA) scan, and CT angiography.

Findings:

The renal lesion was diagnosed as a pseudotumor, an hypertrophied portion of normal renal parenchyma in an atrophic right kidney.
This diagnosis was confirmed through a multimodal imaging approach, including ultrasound, MRI, DMSA, and CT angiography.

Implications:

Accurate diagnosis via advanced imaging techniques can prevent unnecessary surgical interventions in pediatric renal masses.
This case underscores the importance of comprehensive imaging in diagnosing the cause of hypertension and acute kidney injury in children.
