Pseudovitelliform Subfoveal Deposit in Waldenström’s Macroglobulinemia
Background: Waldenström’s macroglobulinemia may be complicated by retinal hemorrhages, retinal vein occlusion, serous macular detachment or macular edema. We report a patient with pseudovitelliform subfoveal deposit complicating Waldenström’s macroglobulinemia. Case Report: A 56-year-old man presented with hyperviscosity syndrome due to Waldenström’s macroglobulinemia. After systemic therapy, a large serous retinal detachment persisted in the left eye. A pseudovitelliform subfoveal deposit was observed in the right eye. Conclusion: Pseudovitelliform subfoveal deposits may be part of the spectrum of ocular complications in Waldenström’s macroglobulinemia. They could be due to accumulation of macroglobulins
Influence of residual moisture and sealing atmosphere on viability of two freeze-dried viral vaccines
This study demonstrated the complexity of the factors leading to changes in the infectivity titers of freeze-dried canine distemper and poultry infectious bronchitis viral vaccines. The change in moisture content during the storage period was an additional parameter which may influence the infectivity titer. The results emphasized the difficulty of predetermining variations in infectivity titers from the initial residual moisture. The analysis of the variations in infectivity titers during the storage of two vaccines led to the formulation of a hypothesis of the presence of two components of different thermostability. Moreover, the temporary increase in the infectivity titer of infectious bronchitis vaccine stored progressively dissociating during storage concurrent with a progressive inactivation of infectious particles.</jats:p
