Maternal-Newborn ABO Blood Group Congruence Among Consecutive Births and Risk of Serious Neonatal Infection: Retrospective Cohort Study.

Background: Differing ABO blood groups between a mother and her fetus may confer a lower risk of serious neonatal infection. How sensitization in the first pregnancy influences this phenomenon in a subsequent pregnancy is unclear. Accordingly, this study determined whether maternal-newborn ABO blood group incongruence in a first pregnancy further modifies the risk of serious infection in a subsequent pregnancy marked by ABO incongruency.

Extrafollicular Adenomatoid Odontogenic Tumors: A Series of Five Rare Cases with an Insight into Its Clinicopathological Aspects.

Adenomatoid odontogenic tumors (AOT), first described by Steensland in 1905, are benign, slowly enlarging, nonaggressive, odontogenic epithelial neoplasms comprising 3%-7% of all odontogenic tumors. They tend to originate from the dental lamina remnants or the reduced enamel epithelium. Mutation at codon 12 of KRAS oncogene (Kirsten rat sarcoma viral oncogene homolog) plays a pivotal role in the pathogenesis.

A rare case of recurrent adenoid cystic carcinoma of the breast with weak hormone receptor positivity.

Adenoid cystic carcinoma (ACC) of the breast is an exceptionally rare malignancy, accounting for less than 0.1% of all breast cancers. Despite its favorable prognosis, optimal management remains undefined due to its rarity and lack of consensus guidelines.

Percutaneous Removal of Cardiac Papillary Fibroelastomas.

Papillary fibroelastomas (PFEs) are primary cardiac tumors associated with significant embolic risk. Surgical excision or medical therapy with antiplatelets and/or anticoagulants have been the treatment options for symptomatic patients. This paper reports our early experiences of percutaneous removal of PFE using mechanical aspiration techniques.
