Acute hemiplegia as a rare presentation of infantile Guillain-Barré syndrome.

Guillain-Barré syndrome (GBS) usually presents in a symmetrical ascending fashion of weakness. We present a 6-month-old male infant who presented to our emergency room with acute left-sided limb weakness and head lag 3 days after a febrile upper respiratory tract infection. A diagnosis of GBS was established by confirming high cerebrospinal fluid protein, motor nerve reduced amplitude, and prolonged conductions, and MRI T2 high signal intensity affecting the ventral roots of the spinal cord. He showed remarkable clinical and neurophysiological improvement after intravenous immunoglobulin and intensive physiotherapy. The occurrence of infantile acute hemiplegia as a presentation of GBS is rare. This report highlights the importance of considering GBS in the differential diagnosis so that early effective treatment may be started.

A case of extreme prematurity and delayed diagnosis of pyridoxine-dependent epilepsy.

Pyridoxine-dependent epilepsy presents early in life, even in utero. It is usually refractory to conventional antiepileptic medications and responds only to lifelong pyridoxine supplementation. Seizures are usually generalized tonic clonic. We report a 3-year-old child that was born prematurely at 25 weeks of gestation. He presented with abnormal movements in the second month of life. At 10 months of age he presented with status epilepticus, which was refractory to multiple antiepileptic medications and was controlled with intravenous pyridoxine. An elevated level of a-aminoadipic semialdehyde excretion in the urine supported the diagnosis of pyridoxine-dependent epilepsy. Subsequently, a c.1195G>C homozygous mutation in the 5q31 aldehyde dehydrogenase 7A1 gene was confirmed. This case calls for considering pyridoxine-dependent epilepsy and its early management in cases with resistant seizures; even in the presence of extreme prematurity with its neurological consequences.
