Changes in vitamin D status considering hemodilution factors in Japanese pregnant women according to trimester: A longitudinal survey.

Objectives: There have been no longitudinal surveys on the changes in 25-hydroxyvitamin D [25(OH)D] while considering hemodilution factors among pregnant Japanese women. Therefore, we examined 25(OH)D levels as well as red blood cell count (RBC), hemoglobin (Hb), and Hematocrit (Hct) at the three trimesters among pregnant Japanese women to determine the distribution of serum 25(OH)D levels and the influence of hemodilution.

Design: This was a longitudinal study.

Human papillomavirus infections among Japanese women: age-related prevalence and type-specific risk for cervical cancer.

To obtain baseline data for human papillomavirus (HPV) screening and vaccination in Japan, we analyzed HPV DNA data from 2282 Japanese women (1517 normal cytology, 318 cervical intraepithelial neoplasia [CIN] grade 1, 307 CIN2-3, and 140 invasive cervical cancer [ICC]) that visited the University of Tsukuba Hospital or Ibaraki Seinan Medical Center Hospital for screening or treatment of cervical diseases between 1999 and 2007. An L1-based PCR method was used for individual HPV genotyping. The most common HPV types in ICC were, in order of decreasing prevalence, HPV16 (40.

Acquired haemophilia due to factor VIII inhibitors in ovarian hyperstimulation syndrome: case report.

A 31-year-old nulligravida woman developed an acquired factor VIII inhibitor associated with severe ovarian hyperstimulation syndrome (OHSS). She developed haematouria, ecchymosis, and intramuscular bleeding following the severe OHSS.
