This study aims to evaluate the potential of percutaneous patent foramen ovale (PFO) closure to improve the headache in patients with migraine and PFO, and discuss the difference between the randomized controlled trials (RCTs) and the single-center studies. Patients of migraine with a large shunt of PFO, who experienced ≥2 headache attacks per month and failed ≥2 categories of standardized medication, underwent PFO closure in First Affiliated Hospital of Xi'an Jiao Tong University. The clinical outcomes, including frequency and duration of headache attacks, Headache Impact Test (HIT-6) score, and Visual Analogue Scale (VAS) score, were evaluated at 3, 6, and 12 months of follow-up after the PFO closure. ⋯ Migraine was completely relieved in 54 (40.30%) patients during 12 months' follow-up. The frequency of migraine was reduced by >50% in 44 (32.84%) patients at 3 months' follow-up and increased to 48 (35.82%) at 12 months' follow-up. 31.03% patients remained residual shunt after 6 months of closure with varying improvements of headache. This study confirmed that PFO closure can effectively reduce frequency and duration of migraine and improve quality of life, but the definitive indications and long-term effect still need further research.

Influenza outbreaks occur annually and account for significant morbidity and mortality. The overall burden of influenza infections, in the USA, for the 2017-2018 season, was an estimated 45 million cases, 810 000 hospitalizations and 61 000 deaths. Literature suggests that leukocyte count and differential, particularly lymphopenia and/or monocytosis, can provide diagnostic value for influenza infection. ⋯ Patients were divided into two cohorts, based on whether they had laboratory-confirmed influenza versus another confirmed upper respiratory tract viral infection (influenza-like illness (ILI)). L:M was compared between the two groups and was found to be lower in the influenza group compared with the ILI group (p<0.0001). Results of this study demonstrate that a L:M<2 has significant diagnostic value in the acute phase of influenza and can be used for earlier detection and management of this disease, in order to improve clinical outcomes.

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare benign rheumatological condition characterized by sudden-onset symmetrical distal extremity edema. It can present as an isolated disease process or could be associated with other conditions. Rheumatoid factor and anticitrullinated protein antibodies are negative by definition. ⋯ Other management options for refractory cases have also discussed. Value of several imaging modalities in diagnostic evaluation of this disease entity is touched on. Since RS3PE can be associated with other diseases, specifically cancer, timely diagnosis of this condition is necessary.
