Summary
A 7-year-old boy with recurrent hypoglycaemic seizures was diagnosed with septo-optic dysplasia. Early diagnosis and treatment of this rare condition are crucial for preventing complications.
Area of Science:
- Pediatric Endocrinology
- Neurodevelopmental Disorders
- Genetics
Background:
- Recurrent hypoglycaemic seizures in children can indicate underlying endocrine or neurological issues.
- Septo-optic dysplasia is a congenital disorder characterized by optic nerve hypoplasia, midline brain abnormalities, and pituitary deficiencies.
Observation:
- A 7-year-old boy presented with tonic-clonic seizures and severe hypoglycemia, with a history of similar episodes, strabismus, and cryptorchidism.
- Physical examination revealed a hoarse voice, dry skin, cold extremities, and growth deceleration (height in the third percentile).
- Radiography showed delayed bone age, and lab studies confirmed growth hormone deficiency and central hypothyroidism.
Findings:
- Brain MRI revealed an ectopic neurohypophysis, and neuro-ophthalmology confirmed left optic nerve hypoplasia.
- The patient was diagnosed with septo-optic dysplasia (SOD), a rare congenital disorder.
- Hormone replacement therapy with thyroid extract and recombinant growth hormone led to clinical improvement.
Implications:
- This case highlights the importance of thorough clinical evaluation in children with recurrent hypoglycemia and dysmorphic features.
- Early diagnosis of septo-optic dysplasia is critical to initiate timely hormonal replacement and prevent long-term morbidity.
- Multidisciplinary assessment, including endocrinology, neurology, and ophthalmology, is essential for managing complex cases of hypopituitarism.

01:20The 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,...

01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
01:19Septins
Septins are protein filaments forming the cytoskeleton along with the microtubules, microfilaments, intermediate filaments, and other accessory proteins. In 1971 while studying the cell division cycle in mutant Saccharomyces cerevisiae Harwell et al. first identified the septin-related genes playing a crucial role in yeast cytokinesis. Fluorescence microscopy revealed that these proteins localize at the budding neck as rings. These ring-like proteins were then named Septins by John Pringle, and...
