A FSH-secreting pituitary adenoma discovered after ovarian hyperstimulation syndrome: a case report, illustrating pitfalls in the interpretation of serum FSH levels.

Background: Most cases of ovarian hyperstimulation syndrome (OHSS) are caused by infertility treatment using human menopausal gonadotropin (HMG) and human chorionic gonadotropin (hCG). OHSS is widely known to have a "spoke-wheel" appearance on imaging, presenting as bilateral symmetric enlargement of ovaries with multiple cysts of varying sizes. When this spoke-wheel appearance is observed in patients not undergoing infertility treatment, tumor-derived hormones such as follicle-stimulating hormone (FSH) and hCG should be measured.

Different sensitivities of porcine coronary arteries and veins to BAY 60-2770, a soluble guanylate cyclase activator.

Nitric oxide (NO)-donor drugs, which stimulate reduced form of soluble guanylate cyclase (sGC), have different efficacy to the arteries and veins. This study examined whether sGC activators, which activate oxidized/apo sGC, also have arteriovenous selectivity similar to that of NO-donor drugs. The mechanical responses of the isolated blood vessels were assessed using the organ chamber technique and protein expression was verified using western blotting.

Clinical practice guidelines for management of disseminated intravascular coagulation in Japan 2024. Part 1: sepsis.

The Japanese Society on Thrombosis and Hemostasis (JSTH) published the first-ever disseminated intravascular coagulation (DIC) guidelines in 2009. Fifteen years later, the JSTH developed new guidelines covering DIC associated with various underlying conditions. These guidelines were developed in accordance with the GRADE system to determine the strength of the recommendations and certainty of the evidence.

Clinical practice guidelines for management of disseminated intravascular coagulation in Japan 2024. Part 2: hematologic malignancy.

Disseminated intravascular coagulation (DIC) associated with hematologic malignancies, particularly acute promyelocytic leukemia (APL), is characterized by marked fibrinolytic activation, which leads to severe bleeding complications. Therefore, appropriate diagnosis and management of DIC are crucial for preventing bleeding-related mortality. However, to date, no clinical guidelines have specifically addressed hematologic malignancy-associated DIC.
