Orange juice concentrates were packaged aseptically by a "Dole" aseptic canning machine using 6 oz metal cans. The final juice products (ll", 34', 44', 58" Brix) were stored between -18" and 36°C and tested periodically for nonenzymatic browning, ascorbic acid destruction, furfural and sensory changes. Nonenzymatic browning, the main deterioration phenomena in these products, was satisfactorily retarded at 12°C or lower. Ascorbic acid destruction rate constant was dependent on temperatures between 5 and 25"C, and was affected by degree of juice concentration. Furfural accumulation in juice was higher than that in 58' Brix concentrate. Orange juice concentrate of 58" Brix did not show flavor changes after storage at 5°C or 12°C for 17 or 10 months, respectively, when evaluated after reconstitution to 11' Brix.

BackgroundPatients with cerebral aneurysms treated with the Pipeline embolization device (PED) are maintained on dual antiplatelet therapy (DAPT) to prevent thromboembolic complications. Rates of minor, “nuisance” bleeding in these patients remain unknown. We sought to evaluate the frequency and factors associated with this bleeding and its effect on DAPT compliance.MethodsWe performed a multicenter retrospective cohort study on consecutive cases of intracranial aneurysms treated with PED. Patient characteristics, aneurysm characteristics, and bleeding complications were analyzed. Severity of bleeding was defined according to a previously published classification defining nuisance bleeding as easy bruising, bleeding from small cuts, petechia, and ecchymosis.Results245 PED aneurysm procedures on 243 patients were retrospectively collected from three academic centers over a 4.25-year period. Sixty-seven patients (27%) had nuisance bleeds. Patients with a higher risk of nuisance bleeding were older (59.1±3.4 vs . 54.7±2.2, P=0.032). Patients with nuisance bleeds were more likely to have their DAPT regimen changed or dose lowered (29% vs 8.3%, P<0.001), were on DAPT for less time (10.0 months±2.60 vs. 14.6 months±1.95, P=0.005) and were more likely to have aneurysm occlusion at 6 months (P<0.001). Stepwise logistic regression found age predictive of a nuisance bleed (OR=1.033)ConclusionsNuisance bleeding was a common complaint of PED-treated aneurysm patients maintained on DAPT. Increasing age and aneurysmal occlusion at 6 months were the only factors predictive of nuisance bleeds. Clinicians were more likely to adjust antiplatelet regimens or stop DAPT early given a nuisance bleed.

Sometimes the only indicator of a serious infection in a neonate is a fever. Citrobacter koseri (C. koseri) has been reported to cause neonatal brain abscesses in the setting of meningitis. Although rare, pneumocephalus, secondary to C. koseri , carries a very high mortality. A 17-day-old male presented to the emergency department with a fever, decreased oral intake, and lethargy. The patient developed pneumocephalus and cerebral edema and was diagnosed with C. koseri meningitis, leading to death. This case demonstrates the presentation of C. koseri meningitis with pneumocephalus and cerebral edema in a neonate presenting with fever.
