In contrast to other cryoprecipitable coagulation proteins, pFXIII is only mildly enriched in cryoprecipitate when compared with FFP (approx. two- to threefold). Although both products can provide effective pFXIII replacement, FFP may be preferred when infusion volume is not a major consideration and pFXIII concentrates are not available. VWF is substantially enriched in cryoprecipitate (approx. ninefold compared with its concentration in FFP), with VWF activity content exceeding that of FVIII by approximately 26 percent on average.

This retrospective review suggests that concomitant use of an SSRI during treatment does not adversely affect survival. There was no increased toxicity with the use of SSRI concurrent with treatment of newly-diagnosed GBM.

C-terminal somatic mutations in nucleophosmin (NPM), a nucleolar shuttling protein that binds p53 and p19(Arf), were recently described in karyotypically normal acute myeloid leukaemia (AML). We analysed primary marrow samples from 150 patients with various chronic myeloid disorders for mutations in the NPM1 gene encoding NPM. NPM1 mutations (tetranucleotide duplication) were detected in three patients, all of whom had chronic myelomonocytic leukaemia (CMML) and a short (<1 year) survival, with rapid progression to overt AML. All other patients were NPM1-wild type in the region analysed. In conclusion, C-terminal NPM mutations are uncommon in chronic myeloid neoplasia, but if present may represent an evolving leukaemic clone.

Outcomes of external beam radiotherapy (EBRT) in advanced medullary thyroid carcinoma (MTC) are largely unknown. Retrospective review of data from patients with MTC, diagnosed from June 1, 1970, through December 31, 2007. Overall survival and locoregional tumor control rates were calculated. Seventeen patients had adjuvant or palliative EBRT delivered to 41 sites. Six patients initially had adjuvant EBRT (median, 60.80 Gy); none had relapse in the treated area. Five patients with locoregional recurrence after surgery were treated (median, 59.40 Gy), and durable disease control was achieved in 3. Twelve patients received palliative EBRT to 29 sites of metastatic disease (median, 30.00 Gy), which provided sustained symptom relief at 45% of sites. Five- and ten-year overall survival rates were 44% and 19%, respectively. Adjuvant EBRT may be most effective for prevention of locoregional recurrence. EBRT may provide sustained control of advanced, metastatic disease in select patients.

In patients presenting with chronic fatigue and/or orthostatic intolerance, low ferritin levels and hypovitaminosis D are common, especially in patients with PT.
