Influenza has significant morbidity and mortality. Some experts consider infection with influenza B as milder than that with influenza A. The objective of this study is to evaluate the outcomes of hospitalized patients with laboratory-confirmed influenza A or B in 2017-2018 influenza season. All hospitalized patients between October 2017 and April 2018 with laboratoryconfirmed influenza A and B were included. The primary composite outcomes were pneumonia/myocarditis/encephalitis, mechanical ventilation, ICU admission, and 30-day mortality. Secondary outcomes were 30-/90-day mortality, length of hospital stay, and readmission rates. The study included 201 influenza A and 325 influenza B. For the primary composite outcome, no significant difference was demonstrated between influenza A and B. Rates of mortality were similar at 30 and 90 days. Influenza A had higher pneumonia rates and mechanical ventilation. On multivariate analysis, higher Charlson's score, hypoalbuminemia, and vasopressor use were associated with 30-day mortality, while infection with either influenza A or B was not. Influenza A was associated with higher pneumonia and mechanical ventilation rates. However, influenza B resulted with similar 30-day mortality rate as influenza A.

Retained products of conception (RPOC) occur in up to 1% of deliveries. 1 Although uncommon, surgical procedures for removal of RPOC may be required in these parturients, associated with the long-term sequelae of intrauterine adhesions, abnormal placentation, and infertility. 2,3 Consequently, Asherman's syndrome following postpartum surgical procedures for removal of RPOC has emerged as a major cause for litigation. 4 With the aim of optimizing the postpartum management of women considered at risk for RPOC while reducing the rates of surgical interventions for RPOC removal, we previously described a postpartum clinical and ultrasound follow-up protocol, whereby women considered at risk for RPOC underwent sequential ultrasound scans. 5,6 In cases of persistent abnormal ultrasound findings suspicious for RPOC between 6 and 8 weeks from delivery, hysteroscopy for diagnosis and RPOC removal was offered. However, some women required earlier surgical interventions, by hysteroscopy or by suction curettage, because of
