Association between hospital case volume and maternal adverse events in patients with placental abruption: An analysis using a Japanese national inpatient database.

Objective: To clarify the relationship between the prognosis of patients with placental abruption (PA) and the healthcare delivery system using data from a large national inpatient database in Japan.

Methods: Using the Diagnosis Procedure Combination database, we conducted a retrospective cohort study with the data of patients in almost 1000 hospitals with the primary diagnosis of PA who were hospitalized from April 2014 to March 2021. We divided the hospitals into four groups based on the number of deliveries per month.

Ovarian Clear Cell Carcinoma and Rectal Adenocarcinoma Detected by Tubo-Ovarian Abscess: A Case Report.

Most cases of tubo-ovarian abscess (TOA) are due to transvaginal infection, while other internal diseases may also be associated with TOAs. We experienced a case of ovarian clear cell carcinoma and rectal carcinoma that was discovered to be a result of TOA. A 46-year-old woman was diagnosed with TOA and referred to our hospital.

Retrospective analysis of prognosis using the Gynecology Oncology Group score of stage IB-IIA node negative uterine cervical cancer after radical hysterectomy and trachelectomy.

There is currently controversy regarding the criteria for low and intermediate risk of cervical cancer (CC) after surgery. In the present study, the Gynecology Oncology Group (GOG) score was used to detect intermediate risk. Adjuvant radiotherapy was applied in the case of a GOG score >120.

Synchronous Occurrence of Ovarian Seromucinous Carcinoma and Endometrial Mucinous Carcinoma: A Case Report.

Endometrioid carcinoma is the most common histological type of concurrent synchronous cancers of the uterus and ovary. Here we report a case of synchronous seromucinous carcinoma of the ovary and mucinous carcinoma of the endometrium with a literature review. A 51-year-old multiparous female complained of irregular bleeding and shortness of breath.

Hypersensitivity Reaction to Carboplatin in Gynecologic Cancer: A Case Report and a Review of the Literature.

A combination chemotherapy of paclitaxel plus carboplatin (TC) is the most frequently used regimen for gynecological malignancies. As long as it is effective, a carboplatin-containing combination chemotherapy is used for every relapse. This implies that the number of platinum administrations and the frequency of hypersensitivity reaction (HSR) increase as the prognosis improves.

Pregnancy after hysteroscopic metroplasty under laparoscopy in a woman with complete septate uterus: a case report.

A 31-year-old nulligravid woman with a 3 year history of infertility visited our hospital. After consultation and a transvaginal ultrasound and MR imaging, her uterine anomaly was identified as complete septate uterus: class V (a) by the American Fertility Society (AFS). She had a doubled uterine cervix and a vaginal septum.

Carbon-13 labeling for quantitative analysis of molecular movement in heterogeneous organic materials using secondary ion mass spectrometry.

Secondary ion mass spectrometry (SIMS) is used to probe the movement of macromolecules in heterogeneous organic systems. Using 13C tracer labeling and two model systems, polystyrene/poly(2-vinylpyridine) (PS/P2VP) and polystyrene/poly(4-bromostyrene) (PS/P4BrS), the diffusion of 13C-labeled PS has been investigated near the respective heterogeneous interfaces using a CAMECA-IMS-6F magnetic sector mass spectrometer. 13C labeling has been shown to greatly minimize matrix effects (i.
