Cranial and intra-axial metastasis originating from a primary ovarian Dysgerminoma.

Dysgerminomas are aggressive germ cell tumors that typically have a favorable prognosis, especially in patients diagnosed with early stage disease. We recount the history of a 23-year-old woman who was treated for a stage IA ovarian dysgerminoma in November 2017. Postoperatively, the patient was noncompliant insofar as obtaining routine lab evaluations; ten months later, she was diagnosed with a cranial metastasis that extended into the meninges.

Development of a wound dressing composed of a hyaluronic acid sponge containing arginine.

Spongy sheets composed of cross-linked high-molecular-weight (HMW) hyaluronic acid (HA) were prepared by freeze-drying an aqueous HMW-HA solution containing cross-linking agent (Group I). The Group I sheet was immersed into an aqueous low-molecular-weight (LMW) HA solution with or without L-arginine (Arg) and was then freeze-dried to prepare several types of spongy sheets (Groups II-V). The amount of Arg was 1.
