Introduction: Degenerative spondylosis and kyphoscoliosis are increasingly recognized entities in patients with Parkinson's disease. Surgical treatment with spinal fusion can be complicated due to poor bone quality and muscular dysfunction in this patient population. The goal of this paper is to investigate surgical outcomes in Parkinson's patients undergoing spine surgery.
Methods: We performed a literature review using the PubMed and Google Scholar search engines investigating "Parkinson's disease and spinal fusion surgery" from the period of 2000 to 2013. The inclusion criteria included only English articles with Parkinson's patients that underwent spinal surgery. We identified and reviewed all six articles that included ninety-five patients with Parkinson's disease who underwent spinal surgery.
Results: A total of 95 patients with Parkinson's disease who underwent spinal fusion surgery were reviewed with average patient age of 69 and a 3:4 male to female ratio. With an average follow up of 40 months, 46 out of 73 patients (63%) were judged to have satisfactory outcomes with poor outcomes noted in the remaining 37%. These included but were not limited to pseudoarthrosis, hardware failure/pullout, development of adjacent level disease, persistent kyphosis or sagittal imbalance, and no improvement or worsening in their postoperative visual analog pain scale. There was a 45% (29/65) revision rate and a 59% (30/51) complication rate following the index procedure.
Conclusion: It remains unclear whether Parkinson's patients benefit from spinal fusion surgery. Further prospective research is warranted to investigate surgical outcomes in this subset of patients.

C19orf12 gene variants causing mitochondrial membrane protein-associated neurodegeneration (MPAN).

Mitochondrial membrane protein-associated neurodegeneration (MPAN) is a rare neurodegenerative disorder characterized by spastic paraplegia, parkinsonism and psychiatric and/or behavioral symptoms caused by variants in gene encoding chromosome-19 open reading frame-12 (C19orf12). We present here seven patients from six unrelated families with detailed clinical, radiological, and genetic investigations. Childhood-onset patients predominantly had a spastic ataxic phenotype with optic atrophy, while adult-onset patients were presented with cognitive, behavioral, and parkinsonian symptoms.

Distinguishing between Parkinson's disease (PD) and essential tremor (ET) can be challenging sometimes. Although positron emission tomography can confirm PD diagnosis, its application is limited by high cost and exposure to radioactive isotopes. Patients with PD exhibit loss of the dorsal nigral hyperintensity on brain magnetic resonance imaging (MRI).

Metabotropic glutamate (mGlu) receptors are candidate drug targets for therapeutic intervention in Parkinson's disease (PD). Here we focused on mGlu3, a receptor subtype involved in synaptic regulation and neuroinflammation. mGlu3 mice showed an enhanced nigro-striatal damage and microglial activation in response to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).

Background: Vanishing white matter disease (VWMD) is a rare autosomal recessive leukoencephalopathy. It is typified by a gradual loss of white matter in the brain and spinal cord, which results in impairments in vision and hearing, cerebellar ataxia, muscular weakness, stiffness, seizures, and dysarthria cogitative decline. Many reports involve minors.

Cerebral venous sinus thrombosis is an uncommon sequela of low intracranial pressure, which may result from a lumbar puncture (LP). We describe a case of a patient in their 40s presenting with 48 hours of persistent headache following intrathecal administration of nusinersen for spinal muscular atrophy (SMA) type 3. There were no focal neurological signs or symptoms apart from baseline symmetrical proximal limb weakness attributed to SMA.
