Multiple Sclerosis (MS) treatment with natalizumab is associated with Progressive Multifocal Leukoencephalopathy (PML). The risk of PML being related to the anti-JCV antibody index is well established, but there is less known about seroconversion rates in natalizumab-treated patients and longitudinal variation in the anti-JCV antibody index. Our objective was to assess anti-JCV antibody prevalence in an MS population and to evaluate the evolution of the anti-JCV antibody index in natalizumab-treated patients. ⋯ In conclusion, anti-JCV antibody prevalence in our population is comparable to other reported cohorts. The seroconversion rate increased with treatment duration. We found a high fluctuation in the antibody index in JCV+ patients.

Review Case Reports
Immune mediated neuropathy following checkpoint immunotherapy.
Checkpoint immunotherapy has revolutionised cancer therapy and is now standard treatment for many malignancies including metastatic melanoma. Acute inflammatory neuropathies, often labelled as Guillain-Barre syndrome, are an uncommon but potentially severe complication of checkpoint immunotherapy with individual cases described but never characterised as a group. We describe a case of acute sensorimotor and autonomic neuropathy following a single dose of combination ipilimumab and nivolumab for metastatic melanoma. ⋯ Treatment was variable and often in combination. 11 cases received steroid therapy with only 1 death within this group, whereas of the 4 patients who did not receive steroid therapy there were 3 deaths. In conclusion checkpoint immunotherapy - induced acute neuropathies are distinct from and progress differently to Guillain-Barre syndrome. As with other immunotherapy related adverse events corticosteroid therapy should be initiated in addition to usual therapy.

Review Meta Analysis
Efficacy and safety of etanercept in the treatment of sciatica: A systematic review and meta-analysis.
Etanercept might be promising to alleviate sciatica caused by lumbar disc herniation and spinal stenosis. However, the results remained controversial. We conducted a systematic review and meta-analysis to evaluate the efficacy of etanercept in patients with sciatica. ⋯ Etanercept showed no increase in Oswestry Disability Index (ODI) compared with placebo (Std. mean difference=-0.83; 95% CI=-2.03 to 0.37; P=0.18) and steroids (Std. mean difference=-0.19; 95% CI=-1.15 to 0.77; P=0.70). Etanercept treatment was associated with a significantly reduced pain in leg and back compared to placebo and may possibly improve leg pain relief compared to steroids, but failed to improve ODI. Etanercept should be recommended for sciatica with caution because of heterogeneity.

Bidirectional co-morbidity between migraine and depression has been observed. Mood disorders are associated with an increased risk of both migraine and irritable bowel syndrome (IBS). The aim of this study was to evaluate the risk of developing IBS in patients with migraine and to compare the risks between those with and without anxiety or depression. ⋯ When separating the cohort into those with mood disorder and without it, migraine is a significant risk factor of IBS in patients without mood disorders, but not in patients with co-existed mood disorders. The findings of this study suggest that migraine is a risk factor of future IBS development for those without comorbid anxiety or depression. However, migraine does not contribute significantly additional risk to IBS development in patients with comorbid anxiety or depression.

The introduction of flow diverting stents, particularly for treatment of petrous to supraclinoid internal carotid artery aneurysms, has greatly impacted endovascular treatment of intracranial aneurysms. Despite their high efficacy, complications, such as ischemic events, distal hemorrhage, or problems with stent deployment, remain a significant concern. We present the first reported case of acute distal migration of a Pipeline Embolization Device (PED). ⋯ Repeat angiography revealed acute distal migration of the PED and an occlusive thrombus. Thought to be secondary to chronic in-stent thrombosis, distal migration has been previously described in a delayed fashion over weeks to months. However, to our knowledge, this is the first reported case of distal flow diverter migration in an acute setting immediately following the procedure.
