Purpose of Review
Recurrent painful ophthalmoplegic neuropathy (RPON), formerly known as ophthalmoplegic migraine, is an uncommon disorder with repeated episodes of ocular cranial nerve neuropathy associated with ipsilateral headache. This review discusses the clinical presentation, current understanding of the pathophysiology, key differential diagnoses, and evaluation and treatment of RPON.Recent Findings
The literature is limited due to the rarity of the disorder. Recent case reports and series continue to suggest the age of first attack is most often during childhood or adolescence as well as a female predominance. Multiple recent case reports and series demonstrate focal enhancement of the affected cranial nerve, as the nerve root exits the brainstem. This finding contributed to the current classification of the disorder as a neuropathy, with the present understanding that it is due to a relapsing-remitting inflammatory or demyelinating process. The link to migraine remains a cause of disagreement in the literature.Summary
RPON is a complex disorder with features of inflammatory neuropathy and an unclear association with migraine. Regardless, the overall prognosis is good for individual episodes, but permanent nerve damage may accumulate with repeated attacks. A better understanding of the pathogenesis is needed to clarify whether it truly represents a single disorder and to guide its treatment. Until that time, a combined approach with acute and preventive therapies can mitigate acute symptoms as well as attempt to limit recurrence of this disabling syndrome.25.

ObjectivesThe Sub-Saharan African (SSA) region now has the highest estimated effect size of hypertension for stroke causation worldwide. An urgent priority for countries in SSA is to develop and test self-management interventions to control hypertension among those at highest risk of adverse outcomes. Thus the overall objective of the Phone-based Intervention under Nurse Guidance after Stroke II study (PINGS-2) is to deploy a hybrid study design to assess the efficacy of a theoretical-model-based, mHealth technology-centered, nurse-led, multi-level integrated approach to improve longer term blood pressure (BP) control among stroke survivors.Materials and methodsA phase III randomized controlled trial involving 500 recent stroke survivors to be enrolled across 10 Ghanaian hospitals. Using a computer-generated sequence, patients will be randomly assigned 1:1 into the intervention or usual care arms. The intervention comprises of (i) home BP monitoring at least once weekly with nurse navigation for high domiciliary BP readings; (2) medication reminders using mobile phone alerts and (3) education on hypertension and stroke delivered once weekly via audio messages in preferred local dialects. The intervention will last for 12 months. The control group will receive usual care as determined by local guidelines. The primary outcome is the proportion of patients with systolic BP <140 mm Hg at 12 months. Secondary outcomes will include medication adherence, self-management of hypertension, major adverse cardiovascular events, health related quality of life and implementation outcomes.ConclusionAn effective PINGS intervention can potentially be scaled up and disseminated across healthcare systems in low-and-middle income countries challenged with resource constraints to reduce poor outcomes among stroke survivors. 相似文献
