Biomedicines 2021 Sep 23;9(10). Epub 2021 Sep 23.

Department of Pharmacology, School of Medicine, University of Zagreb, 10000 Zagreb, Croatia.

We redefined Robert's prototypical cytoprotection model, namely the intragastric administration of 96% alcohol in order to generate a general peripheral and central syndrome similar to that which occurs when major central or peripheral veins are occluded in animal models. With this redefinition, we used Robert's model to examine the cytoprotective effects of the stable gastric pentadecapeptide BPC 157. The intragastric administration of alcohol induced gastric lesions, intracranial (superior sagittal sinus) hypertension, severe brain swelling and lesions, portal and vena caval hypertension, aortal hypotension, severe thrombosis, inferior vena cava and superior mesenteric vein congestion, azygos vein failure (as a failed collateral pathway), electrocardiogram disturbances, and heart, lung, liver and kidney lesions.

Management of pre-, peri-, and post-menopausal abnormal uterine bleeding: When to perform endometrial sampling?

Int J Gynaecol Obstet 2021 Oct 20. Epub 2021 Oct 20.

Department of Obstetrics-Gynecology, University Hospital, University of Patras School of Medicine, Patras, Greece.

Abnormal uterine bleeding (AUB) is defined as abnormal volume, duration, or frequency of menstrual period and is a common symptom in women of all ages (premenopausal, perimenopausal, and postmenopausal). The acronym PALM-COEIN, introduced by the International Federation of Gynecology and Obstetrics (FIGO), facilitates the evaluation and differential diagnosis of AUB, mostly in premenopausal women with AUB. Endometrial evaluation (including ultrasound or hysteroscopic imaging and tissue sampling) for subtle pathology is proposed in patients who are at high risk for endometrial cancer and in patients at low risk who present with AUB and who present poor correspondence in medical treatment.
