Role of Inferior Vena Cava (IVC) Recanalization in Patients with Back Pain, Secondary to IVC Obstruction in Budd-Chiari Syndrome.

PURPOSE: To study the prevalence of back pain in patients of Budd-Chiari syndrome (BCS) with inferior vena cava (IVC) obstruction, and to evaluate the role of IVC recanalization in resolution of back pain. METHODS: All patients with BCS and IVC obstruction who underwent IVC recanalization between January 2018 and October 2022 were included. Patients with degenerative spine disease or other identifiable causes for back pain were excluded; remaining patients were assessed for the presence of back pain. In patients with back pain, pain relief was assessed at 24 h following IVC recanalization. RESULTS: Fifty-eight patients with BCS and IVC occlusion were identified, of which six with degenerative spine diseases were excluded. Of the remaining 52 patients, 34 (65.4%) had back pain, with pain score between 3 and 9. Engorged epidural venous plexus on preprocedural imaging (p = 0.002), and degree of luminal narrowing (p = 0.021) had a significant association with back pain. Twenty-nine of thirty-four patients (85.3%) with back pain had pain relief immediately following IVC recanalization, more so in patients with engorged epidural venous plexus on preprocedural imaging (p < 0.001). CONCLUSION: Back pain is one of the under-reported symptoms of IVC obstruction in BCS. IVC recanalization by IVC angioplasty with or without stenting relieves back pain due to the decompression of engorged epidural veins.

Huntington's disease in all (three) siblings and their one parent.

Three siblings (two girls and one boy) and their father are reported who developed Huntington's disease (HD). The two girls had onset at less than six years of age, while the boy started with symptoms at 12 years of age. The girl, the child number two, has expired and the youngest one is in a vegetative state. The elder brother is still mildly affected. The disease presented in a severe form and early in the females while it remained mild and presented late in the males. This is a rare disease involving all the three surviving siblings and their father. The diagnosis was confirmed after genetic testing.

Evolution of Ohtahara syndrome to continuous spikes and waves during slow sleep in an infant.

Encephalopathy with electrical status epilepticus in sleep (ESES) is defined as an age-related and self-limited electroclinical syndrome whose etiology is unknown and characterized by continuous spikes and waves during slow sleep (CSWS). Typical CSWS starts at an age of 4 to 5 years and ends by an average of 11 years. We report on an unexpected finding of CSWS in an 18-month-old male whose previous EEG at age 45 days was grossly abnormal with the presence of a burst suppression pattern during wakefulness and sleep. The patient had clinical seizures beginning day 1 of life leading to the suspicion of Ohtahara syndrome (the earliest form of epileptic encephalopathy). Patients with ESES usually have normal EEGs and functional development prior to the onset of CSWS pattern. To our knowledge, this presentation of a neonate with a history of neonatal seizures and developmental delay with an evolution to CSWS has not been described. A sleep record is strongly advised in children with epilepsy (despite the recording of awake EEG abnormalities), especially in patients with behavior or cognitive regression, to rule out the presence of CSWS.

Novel mutation of GLRA1 in Omani families with hyperekplexia and mild mental retardation.

Hyperekplexia is characterized by neonatal hypertonia and exaggerated startle reflex in response to loud noise or tactile stimuli. Mutations in patients with hyperekplexia were evident in several genes encoding proteins involved in glycinergic neurotransmission, i.e., glycine receptor α and ß subunits, collybistin, gephyrin, and glycine transporter 2. We clinically and genetically characterized two large, unrelated consanguineous families with hyperekplexia. Affected members of the two families manifested hyperekplexia with mild mental retardation. Patients exhibited a novel homozygote c.593G>C missense mutation in GLRA1, resulting in amino acid substitution p.W170S in the corresponding mature glycine receptor α1 subunit. This mutation was absent in 400 randomly selected chromosomes in the same population. In conclusion, a novel p.W170S mutation in the extracellular ligand binding domain of glycine receptor α1 subunit was detected in patients with hyperekplexia and mild mental retardation.

Prospective study of children with Guillain-Barre syndrome.

OBJECTIVES: To see the pattern, and outcome of Guillain Barre syndrome in this country. METHODS: All the children under fifteen years with final diagnosis of Guillain-Barre syndrome formed the subjects of the study. All children with acute flaccid paralysis were investigated for the underlying cause. The diagnosis of Gullain-Barre syndrome was made on clinical criteria, cerebrospinal findings and the nerve conduction studies. Intravenous immunoglobulins were given to all and only two children needed plasmapharesis. RESULT: Fifty-two children were seen and constituted 20% of total acute flaccid paralysis cases. Cranial nerves were involved in fifty percent children. Albuminocytological dissociation in cerebrospinal fluid was seen in 97.5 percent cases. Acute relapse was seen in 11.5%. Seventeen percent required ventilation. The complete recovery was seen in 45 to 282 days (mean 68 days). Three children (5.8%) were left with minimal residual defecit. There was no mortality. CONCLUSION: The Guillain-Barre syndrome, though is a serious disease, recovery is the rule in children. Very low mortality and morbidity is seen. Immunoglobulins have reduced the length of hospital stay and also reduced the total time for recovery.
