Twelve tips for developing, implementing, and sustaining medical education fellowship programs: Building on new trends and solid foundations.

Medical education fellowship programs (MEFPs) are a form of faculty development contributing to an organization's educational mission and participants' career development. Building an MEFP requires a systematic design, implementation, and evaluation approach which aligns institutional and individual faculty goals. Implementing an MEFP requires a team of committed individuals who provide expertise, guidance, and mentoring.

CT imaging characteristics of oncocytic adrenal neoplasms (OANs): comparison with adrenocortical carcinomas.

Objective: Oncocytic adrenal neoplasms (OANs) are rare, but are an important subtype of adrenal tumors that is being diagnosed with increasing frequency. Unfortunately, the imaging characteristics of this tumor have not been well described. Our purpose was to identify CT features to differentiate OANs from adrenocortical carcinomas (ACC).

CD34-positive superficial myxofibrosarcoma: a potential diagnostic pitfall.

Background: Myxofibrosarcoma (MFS) arises most commonly in the proximal extremities of the elderly, where it may involve subcutaneous and dermal tissues and masquerade as benign entities in limited biopsy samples. We encountered such a case, in which positivity for CD34 and morphologic features were initially wrongly interpreted as a 'low-fat/fat-free' spindle cell/pleomorphic lipoma. Case series have not assessed prevalence of CD34 reactivity among cutaneous examples of MFS.

Decreased apoptosis in the forebrain of adult male medaka (Oryzias latipes) after aqueous exposure to ethinylestradiol.

Endocrine disrupting compounds (EDCs), especially those that are estrogenic, are an issue of growing concern because they may ultimately adversely affect wildlife survival. 17-beta-Estradiol and its synthetic counterpart, 17-alpha-ethinylestradiol, two common EDCs, are associated with intersex conditions and impaired male reproductive behavior in fish. Male and female Japanese medaka (Oryzias latipes) were exposed to 10 ng/l ethinylestradiol for 6 months.
