Relationship between unremoved cervical polyp in pregnancy and spontaneous preterm birth.

Background: Cervical polyps removed during pregnancy have been reported to be associated with preterm birth; however, the association between unremoved cervical polyps and preterm birth has not been elucidated.

Objective: This study aimed to clarify the relationship between cervical polyps detected before 12 weeks of gestation managed expectantly and spontaneous preterm birth.

Study Design: This retrospective cohort study included pregnant women who visited a tertiary perinatal center before 12 weeks of gestation between January 2015 and December 2019.

Surfactant protein-D attenuates the lipopolysaccharide-induced inflammation in human intestinal cells overexpressing toll-like receptor 4.

Purpose: Necrotizing enterocolitis (NEC) is a devastating inflammatory disease of preterm infants that may depend on overexpression of toll-like receptor-4 (TLR4) in the immature intestine. Surfactant protein (SP)-D is a member of the collectin family and plays an important role in innate immunity, particularly in the airways. Although SP-D also exists in the intestines, little is known about its function.

In vitro activity of five quinolones and analysis of the quinolone resistance-determining regions of gyrA, gyrB, parC, and parE in Ureaplasma parvum and Ureaplasma urealyticum clinical isolates from perinatal patients in Japan.

Ureaplasma spp. cause several disorders, such as nongonococcal urethritis, miscarriage, and preterm delivery with lung infections in neonates, characterized by pathological chorioamnionitis in the placenta. Although reports on antibiotic resistance in Ureaplasma are on the rise, reports on quinolone-resistant Ureaplasma infections in Japan are limited.

Effects of Ureaplasma parvum lipoprotein multiple-banded antigen on pregnancy outcome in mice.

Ureaplasma spp. are members of the family Mycoplasmataceae and have been considered to be associated with chorioamnionitis and preterm delivery. However, it is unclear whether Ureaplasma spp.

Mucinous borderline-like tumor of the gastrointestinal type arising from mature cystic teratoma of the ovary and its immunohistochemical cytokeratin and mucin phenotype.

Malignant transformation is rarely seen in the disease course of mature cystic teratoma (MCT) of the ovary. Adenocarcinoma arising from MCT is especially rare. We herein present the case of a premenopausal woman with a mucinous borderline-like tumor arising from a MCT.
