Histopathologically composed of mixed mesenchymal elements, NCMH exhibits a relatively wide differential diagnosis to include chondromyxoid fibroma, chondroblastoma, aneurysmal bone cyst, fibrous dysplasia, and osteochondromyxoma. An interesting association with pleuropulmonary blastoma has been reported in a small subset of NCMH patients. In the current study, cytogenetic analysis of a NCMH arising in an 11-year-old boy with a past medical history of pleuropulmonary blastoma revealed a novel 12; 17 translocation, t(12;17)(q24.1;q21), as the sole anomaly.”
“The relationship between strain relaxation and microstructure evolution of epitaxial,

(001)-oriented Pt thin films on (001) SrTiO3 substrates is investigated as a function of Pt film thickness. X-ray diffraction shows that the Pt films gradually relax after film coalescence with increasing film thickness. The Pt film surfaces exhibit a cross-hatched surface pattern that AZ 628 molecular weight increases in amplitude and density with film thickness and is due to progressive relaxation of the lattice mismatch strain by BIBF 1120 concentration twinning. The potential of these Pt films as bottom electrodes for functional perovskite films is discussed. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3207795]“
“We encountered an unexpectedly high rate of ovarian cysts in premenopausal women receiving sirolimus and tacrolimus following islet transplantation. The

goal of this retrospective chart review was to determine the frequency of ovarian cysts found on pelvic ultrasound examinations of female islet transplant recipients and to look for potential causal factors. Fifty-seven women with a median age of 42.5 years underwent islet transplantation at the University of Alberta. Ovarian cysts were found in 31 out of 44 (70.5%) premenopausal and two out of 13 (15.4%) postmenopausal women (P = 0.001). No women using combined oral contraception developed ovarian cysts. Eight women required surgery; in four women undergoing Blebbistatin purchase cystectomy

or unilateral oophorectomy, ovarian cysts recurred. Sirolimus withdrawal was associated with a reduction in cyst size and resolution of cysts in 80% of subjects. The risk of ovarian cysts should be discussed with female islet transplant candidates and pelvic ultrasounds performed routinely post-transplant.”
“Myxoinflammatory fibroblastic sarcoma (MIFS) is a low-grade sarcoma generally arising in adults. We present a case of MIFS in a 5-year-old boy with a palpable nodule in the subcutaneous tissue of the scalp. We carried out a literature review to evaluate the diagnostic patterns based on histologic and cytologic features and possible pitfalls and misdiagnoses. A systematic search for articles of interest published between 1995 and 2011 was performed in MEDLINE and PubMed using the words “”myxoinflammatory fibroblastic sarcoma,”" “”myxohyaline tumor,”" and “”inflammatory myxoid tumor.
