Changes in different salivary biomarkers related to physiologic stress in elite handball players: the case of females
2019
AbstractThis study evaluates pre- and post-match concentrations of salivary cortisol, alpha-amylase (AA) and immunoglobulin A (lgA) in a group of 21 elite female handball players in the Spanish national women’s league. The players’ mean age was 23.0 ± 5.4 years. The concentration of the biomarkers was determined using ELISA. Mean playing time was 25.2 min. The players’ cortisol concentration increased significantly (p < 0.05) whereas the IgA concentration fell significantly (p < 0.01) at the end of the match. There were no significant changes in the concentrations of AA between pre and post-match timepoints. The changes observed in the study also depended on the position played; defen…
High prevalence of polycystic ovary syndrome in women with mild hirsutism and no other significant clinical symptoms
2010
Objective To verify the conclusions of the Endocrine Society Guidelines that patients with mild hirsutism and no other important clinical signs (menstrual irregularities, infertility, central obesity, acanthosis nigricans, rapid progression of the hirsutism, clitoromegaly) should not be further studied. Design Retrospective study in patients referred because of mild hirsutism and no other clinical signs. Setting Department of Clinical Medicine of the University of Palermo. Patient(s) One hundred fifty-two patients with mild hirsutism. Intervention(s) Measurement of serum testosterone, dehydroepiandrosterone sulfate, 17-OH-Progesterone, assessment of ovulation by measurement of progesterone …
Endometrial gene expression in the window of implantation is altered in obese women especially in association with polycystic ovary syndrome
2010
Objective To determine whether luteal phase endometrial transcriptome is altered in obese women during the window of implantation (WOI), considering the presence of infertility, fat distribution and association with polycystic ovary syndrome (PCOS). Design Prospective study. Setting University-affiliated infertility clinic, between May 2007 and March 2009. Patient(s) One control group of women with normal weight (n = 4), and four study groups of obese women (n = 6 each one) according to the association with infertility, PCOS, and ovarian stimulation. Intervention(s) The endometrium was biopsied 7 days after LH surge or hCG administration in 28 women. Main Outcome Measure(s) Endometrial gene…
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.
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
1999
Abstract Objective: Although serum leptin is principally influenced by body mass, to understand the role of insulin and androgens in the regulation of serum leptin in normal weight 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. M…
Biochemical composition of salivary stones in relation to stone-and patient-related factors
2018
Background Salivary stones are calcified structures most often found in the main duct of the submandibular or parotid salivary gland. They contain of a core surrounded by laminated layers of organic and inorganic material. Material and Methods Submandibular and parotid sialoliths (n=155) were collected at the department of Oral and Maxillofacial surgery of a general hospital between February 1982 and September 2012. The weight of the sialoliths was determined and the consistency was subjectively classified. Subsequently, the biochemical composition of the stones was determined by wet chemical methods or FT-IR spectrometry. Age and gender of the patients were retrieved from their medical rec…
Assessing the association between unstimulated whole salivary flow rate (UWSFR) and oral health status among healthy adult subjects: A cross-sectiona…
2018
Background This study aimed to test the association between the unstimulated whole salivary flow rate (UWSFR) and the oral health status represented by dental and gingival status among healthy adult subjects. Material and Methods This work was a cross-sectional study of patients attending the undergraduate dental clinics at AlFarabi College for Dentistry and Nursing, Riyadh, Saudi Arabia. The study population consisted of 502 systemically healthy adults aged 18–35 years. UWSFR was collected for all study participants and expressed as ml/min. Oral health status was estimated using the Community Periodontal Index (CPI) and the Oral Hygiene Index-Simplified (OHI-S). The number of decayed teeth…
Sialographic findings in Wharton duct evagination
2009
Ductal evagination is a rare condition affecting the Wharton duct. The aim of this study was to establish the incidence, imaging features and clinical significance of ductal evagination in patients undergoing submandibular gland sialography. The sialographic findings and reports of 322 patients undergoing submandibular gland sialography during the period 1998-2007 were retrospectively reviewed. Ductal evagination was identified on sialograms as a unique diverticulum, filled with contrast medium, of the Wharton duct, with a narrow neck and a blind end. A ductal evagination was found in 5/322 patients with swelling and pain in the submandibular gland. It was always located in the middle tract…
The effect of amifostine or IMRT to preserve the parotid function after radiotherapy of the head and neck region measured by quantitative salivary gl…
2008
Purpose: In this retrospective study, two approaches to preserve the parotid function after radiotherapy (RT) were compared: application of the radioprotective agent amifostine during RT and parotid sparing intensity-modulated radiotherapy (IMRT). Patients and methods: Patients were qualified for this analysis if (1) both parotid glands received a radiation dose of P50 Gy using conventional radiotherapy techniques (cRT) or if they received a parotid sparing IMRT as alternative, if (2) salivary gland scintigraphies before and after RT were performed, and if (3) a normal parotid function was present before RT. Quantitative salivary gland scintigraphy was used to assess the parotid gland funct…
