Ki-67 Expression as a Factor Predicting Recurrence of Ductal Carcinoma In Situ of the Breast: A Systematic Review and Meta-Analysis.

Background: Ki-67 is a marker of proliferating cells; in this meta-analysis we aimed to examine whether Ki-67 expression can predict recurrence rates of breast ductal carcinoma in situ (DCIS).

Materials And Methods: This systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eligible articles were sought in MEDLINE up to April 30, 2017.

An ovarian mass after breast cancer: Metachronous carcinoma or metastasis? A case report.

Introduction: Differentiating between primary and secondary ovarian cancer can be a difficult task. In hereditary conditions breast malignancies and primary ovarian cancer often coexist.

Presentation Of Case: We present a 45-year-old patient with an ovarian mass two years after the diagnosis of a lobular, triple negative breast carcinoma.

Ludovico Maria Barbieri (1662-1728), the unknown 17th century physician.

During the 17th century, Ludovico Maria Barbieri from Imola, Italy, discussed the requirement of a gas, seemingly oxygen, for living beings to function. On 6 December 1680, he published his only known work 'Spiritus nitro-aerei operations in microcosmo' in which he reviewed the function of oxygen and the apparatus he used based on the use of experiments rather than just theory. The scarcity of information about his life and work has resulted usually in him being a neglected figure in Italy.
