Seventy-seven patients with endometrial hyperplasia, 48 with simple hyperplasia without atypia (SH), 17 with complex hyperplasia without atypia (CH), one with simple hyperplasia with atypia (SHA), and 11 with complex hyperplasia with atypia (CHA) were prospectively followed-up by total curettage every 12 months for 3 years. Progression to carcinoma occurred in only one of the 77 patients; she showed grade 1 adenocarcinoma. The overall regression rates were 79% for SH, 100% for SHA, 94% for CH, and 55% for CHA, respectively. In patients with CHA whose disease reverted to normal endometrium, regression was most likely to occur within the first year.
Dilatation and curettage was performed under anesthesia in outpatients in 1,837 patients aged over 26 with a history of abnormal uterine bleeding not associated with pregnancy or ovulation. Fifty-one (2.8%) patients were found to have malignant disease. Of these, 47 patients had endometrial carcinoma. An additional 111 (6.0%) patients were found to have endometrial hyperplasia. The incidence of either malignant disease or endometrial hyperplasia was 9.7% in patients over the age of 40. Complications of this method were noted in 12 (0.7%) patients; only three patients needed to stay in hospital.
PurposeTo determine whether the presence of intact cumulus cells during the preincubation period for ICSI should be considered as a critical factor in fertilization and embryonic development.MethodsThe cohort of this prospective randomized study was limited to infertile women younger than 39 years of age who underwent controlled ovarian stimulation for ICSI between October 2013 and May 2015 and whose embryos were to be incubated until day 5. Women with estradiol levels of <2000 pmol/L on the day of HCG injection were excluded. Cumulus cells were removed immediately after OPU in Group A and at 120 minutes after OPU in Group B. ICSI was performed with all mature oocytes, and fertilized oocytes were cultured to the blastocyst stage. Maturation, fertilization, blastocyst, good quality blastocyst, pregnancy, live birth, and miscarriage rates were compared.ResultsThere were no significant differences in maturation, fertilization, blastocyst, pregnancy, live birth, or miscarriage rates between Groups A and B. However, the percentage of good quality blastocysts was significantly higher in Group B than Group A (52.0% vs 33.1%).ConclusionsIntact cumulus cells should be maintained during the preincubation period, as they are important to embryonic development after fertilization.
Neonatal polycythemia is a perinatal complication in infants of diabetic mothers. The cord CBC (complete blood counts), serum iron, transferrin and ferritin concentrations were studied in newborn infants of 9 GDM (gestational diabetes), 21 NIDDM (noninsulin-dependent diabetes mellitus), and 8 IDDM (insulin-dependent diabetes mellitus) mothers.The RBC (red blood cell) count, Hb (hemoglobin) and Het (hematocrit) of these infants were higher than control infants.There was no difference between the serum iron concentration of the infants of each group diabetic mothers and the infants in the control group, but the transferrin concentration was significantly higher and the ferritin was significantly lower in the infants of diabetic mothers than in those of control mothers. There was a significant negative correlation between transferrin and ferritin (r =-0.491 p <0.001). Erythropoiesis is considered to be enhanced in the fetuses of diabetic mothers, and the iron needed for erythropoiesis is reportedly transported from the mother to the fetus according to the demands of the fetus, but the iron storage was shown to be reduced in the fetuses of diabetic mothers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
