The evaluation of metabolic parameters and insulin sensitivity for a more robust diagnosis of the polycystic ovary syndrome

2007

BACKGROUND: Insulin glargine is a once-daily basal insulin analog with prolonged duration of action and absence of an evident peak. Glargine is associated with reduced frequency of hypoglycemic episodes (mostly nocturnal) as well as effective glycemic control. Maintenance of good metabolic control before conception and throughout pregnancy is essential to lower the risk of fetal malformations. Glargine might be a valuable alternative in the management of pregnancies complicated by diabetes mellitus. However, because its clinical utility has not been established, the use of glargine is not currently recommended during pregnancy. OBJECTIVE: The aim of this study was to retrospectively evaluat…

Laparoscopic surgery for isolated inguinal node relapse of high grade serous ovarian cancer using a bipolar combination instrument

2020

Abstract Objective To demonstrate step-by-step minimally invasive surgical technique for dissection of isolated inguinal node relapse of high grade serous ovarian cancer.

Circulating levels of adipose products and differences in fat distribution in the ovulatory and anovulatory phenotypes of polycystic ovary syndrome.

2009

Central fat distribution is increased in anovulatory women with polycystic ovary syndrome (PCOS) compared with ovulatory PCOS and matched controls. Among secreted adipocytokines, this is reflected mainly in lower levels of adiponectin.

The leptin system during human endometrial receptivity and preimplantation development.

2004

The leptin system is implicated in the regulation of body weight and reproductive function, acting at endocrine and paracrine levels. This ligand-receptor system is mandatory for embryonic implantation in rodents. Here, we investigate the expression pattern of total leptin receptor (OB-R(T)), the long form (OB-R(L)) and short isoforms HuB219.1 and HuB219.3 in the human endometrium. Furthermore, we studied leptin and OB-R(T) mRNA during human embryonic preimplantation development and the embryonic regulation of the endometrial OB-R(L). Leptin receptor expression and its isoforms increase in the luteal phase and peak in the late part. Leptin receptor was localized at the epithelial and glandu…

Evidence for altered adipocyte function in polycystic ovary syndrome.

2005

Background: Adipocytokines are produced by adipose tissue and have been thought to be related to insulin resistance and other health consequences. We measured leptin, adiponectin, and resistin simultaneously in women with polycystic ovary syndrome (PCOS) and age- and weight-matched controls. Our hypothesis was that these simultaneous measurements would help determine whether adipocytokine secretion is abnormal in PCOS independent of body mass and whether these levels are related to insulin resistance as well as other hormonal changes. Methods: Fifty-two women with PCOS and 45 normal ovulatory women who were age- and weight-matched were studied. Blood was obtained for adipocytokines (leptin,…

Evidence that insulin and androgens may participate in the regulation of serum leptin levels in women

Design: Prospective observational study. Setting: Academic practice in reproductive endocrinology. Patient(s): Twenty-one women with polycystic ovary syndrome (PCOS) of normal body weight, 8 apparently normal women with polycystic-appearing ovaries (PAO), and 21 normal women. Intervention(s): Fasting blood levels of luteinizing hormone, follicle-stimulating hormone, testosterone (T), unbound T, dehydroepiandrosterone sulfate (DHEAS), insulin, insulin growth factor–binding protein-1 (IGFBP-1), and leptin.

Lysosomal cathepsins B and L and Stefin A blood levels in patients with hepatocellular carcinoma and/or liver cirrhosis: potential clinical implicati…

1997

The serum levels of lysosomal cathepsin B and L and Stefin A, an intracellular inhibitor of these proteolytic enzymes, were determined in patients with hepatocellular carcinoma (HCC) and/or liver cirrhosis (LC) and correlated with some clinical and biochemical parameters of these diseases. Cathepsin B serum levels were increased in HCC and in LC patients as compared to normal subjects (p < 0.001). However no difference was observed between HCC and LC groups. Interestingly, a significant relationship was evidenced between cathepsin B serum content and the grade of severity of cirrhosis (r = 0.41; p < 0.001). Cathepsin L was significantly elevated only in sera of cancer patients as comp…

Focal lesions in cirrhotic liver: what else beyond hepatocellular carcinoma?

2014

Detection and characterization of focal lesions in the cirrhotic liver may pose a diagnostic dilemma. Several benign and malignant lesions may be found in a cirrhotic liver along with hepatocellular carcinoma (HCC), and may exhibit typical or atypical imaging features. In this pictorial essay, we illustrate computed tomography and magnetic resonance imaging findings of lesions such as simple bile duct cysts, hemangioma, focal nodular hyperplasia-like nodules, peribiliary cysts, intrahepatic cholangiocarcinoma, lymphoma, and metastases, all of which occur in cirrhotic livers with varying prevalences. Pseudolesions, such as perfusion anomalies, focal confluent fibrosis, and segmental hyperpla…
