Endocrine Cancer Risks For Women During The Perimenopause And Beyond., Kimberly Leslie, N. Kumar
Endocrine Cancer Risks For Women During The Perimenopause And Beyond., Kimberly Leslie, N. Kumar
Kimberly K. Leslie
Cancer and its link to reproductive hormones is an area of intense concern for our patients and has been the subject of much speculation. But if estrogen causes breast cancer, for example, most women would eventually develop the disease. We know this is not the case! Actually, estrogen and progesterone have been linked to a decrease as well as an increase in cancer, depending upon the type of tumor under investigation. The purpose of this manuscript is to review the data supporting those relationships.

OBJECTIVE: To determine whether estrogen production and excretion are impaired in gravidas with intrahepatic cholestasis. METHODS: Plasma and urine samples were collected from 13 women from the United States and Chile at 35-38 weeks' gestation with mild (n = 9) or severe (n = 4) intrahepatic cholestasis of pregnancy. Urinary and plasma steroid levels from women with cholestasis were compared with levels from 27 normal pregnant women within the same gestational age range. Urinary concentrations of dehydroepiandrosterone (DHEA), estrone (E1), estradiol (E2), estriol (E3), estetrol, progesterone, and 16-hydroxy-pregnenolone were measured by gas chromatography mass spectrometry, and plasma concentrations of DHEA …

Low Serum Estradiol And High Serum Progesterone Concentrations Characterize Hypertensive Pregnancies At High Altitude., S. Zamudio, Kimberly Leslie, M. White, D. Hagerman, L. Moore
Kimberly K. Leslie
OBJECTIVE: Intrauterine growth retardation and preeclampsia are more common at high than at low altitude. Because altered hormonal profiles have been linked with these disorders, we asked whether placental steroid hormone concentrations were altered during pregnancy at high altitude. METHODS: We measured progesterone, unconjugated estradiol, and estriol (by radioimmunoassay) at weeks 20, 30, and 36 of pregnancy in 18 women at low altitude (1600 m) and 40 women at high altitude (3100 m). RESULTS: Women at 3100 m compared with 1600 m had lower serum estradiol concentrations at week 36 of pregnancy, and lower estriol and higher progesterone concentrations throughout …
Pregnancy Specific Beta 1 Glycoprotein (Sp-1) In Maternal Serum And Amniotic Fluid; Pre-Eclampsia, Small For Gestational Age Fetus And Fetal Distress., R. Silver, K. Heyborne, Kimberly Leslie
Pregnancy Specific Beta 1 Glycoprotein (Sp-1) In Maternal Serum And Amniotic Fluid; Pre-Eclampsia, Small For Gestational Age Fetus And Fetal Distress., R. Silver, K. Heyborne, Kimberly Leslie
Kimberly K. Leslie
Pregnancy specific beta 1 glycoprotein (SP-1) levels have been suggested to correlate with certain obstetrical complications. We compared maternal serum SP-1 levels in normal pregnancies (N = 82), and pregnancies complicated by pre-eclampsia (N = 37), small for gestational age fetuses (N = 8) and fetal distress (N = 13). We also compared levels of this protein in mid-trimester amniotic fluid samples obtained from normal (N = 47) and small for gestational age fetuses (N = 25). Despite trends towards low maternal serum and amniotic fluid SP-1 values in complicated pregnancies, there were no statistically significant differences in their levels …

OBJECTIVE: Activation and dimerization of the ERBB family play a role in the pathogenesis and progression of ovarian cancer. We conducted a phase II trial to evaluate the activity and tolerability of lapatinib in patients with recurrent or persistent epithelial ovarian cancer (EOC) and to explore the clinical value of expression levels of epidermal growth factor receptors (EGFR), phosphorylated EGFR, HER-2/neu, and Ki-67, and the presence of EGFR mutations. METHODS: Eligible patients had recurrent or persistent EOC or primary peritoneal carcinoma, measurable disease, and up to 2 prior chemotherapy regimens for recurrent disease. Patients were treated with lapatinib 1500 mg/day. …
Effect Of Tamoxifen On Endometrial Histology, Hormone Receptors, And Cervical Cytology: A Prospective Study With Follow-Up, Kimberly Leslie, S. Walter, K. Torkko, J. Stephens, C. Thompson, M. Singh
Effect Of Tamoxifen On Endometrial Histology, Hormone Receptors, And Cervical Cytology: A Prospective Study With Follow-Up, Kimberly Leslie, S. Walter, K. Torkko, J. Stephens, C. Thompson, M. Singh
Kimberly K. Leslie
OBJECTIVES: Our major hypothesis for these studies was that tamoxifen's varied effects on the endometrium might be due in part to differences in effect on estrogen and progesterone receptors [ER, progesterone receptor isoform A (PRA), and progesterone receptor isoform B (PRB)]. We aimed to evaluate the changes in histology in serial endometrial biopsies (Em bx), Papanicolaou smears (Pap smears), and endometrial ultrasounds as well as changes in the expression of ER, PRA, and PRB in response to tamoxifen. We propose that understanding and correlating the dynamics of receptor expression with histologic and cytologic changes will help us better understand the …

OBJECTIVE: This study was undertaken to evaluate the relationship between GPR30, classical steroidal receptor expression, and clinical outcome in patients with endometrial carcinoma. STUDY DESIGN: Immunohistochemistry was used to investigate the expression of GPR30, estrogen, progesterone, epidermal growth factor receptors and Ki-67 in 47 consecutive consenting patients with endometrial carcinoma diagnosed between 1997 and 2001. Results were correlated with clinical and pathologic predictors of adverse outcome and survival. RESULTS: GPR30 correlated positively with epidermal growth factor receptor (P = .005), but negatively with progesterone (P = .05) receptor expression. GPR30 overexpression occurred more frequently in tumors with deep myometrial invasion, …

OBJECTIVE: This is a descriptive study that tested the maximum traction residents could apply to forceps during simulations. Visual feedback was then used to reinforce an optimal range of traction, and the ability of residents to reproduce this pull when blinded was assessed. METHODS: Fifty-five residents participated in 6 pulling exercises using an isometric strength testing unit with a real-time computer printout of the force applied. Maximum traction was determined for male and female residents in standing and sitting positions. Visual feedback was then used to estimate whether residents could be trained to reproduce an optimal force range of 30-45 …

BACKGROUND: Preterm birth (PTB) is a substantial health problem that accounts for significant infant morbidity and mortality and poses an economic burden to both individuals and the state of residence. The goal of this study was to identify maternal risk factors for PTB in New Mexico, a poor state with a unique ethnic background, in order to identify populations at increased risk that would benefit from intervention. METHODS: This was a cross-sectional retrospective exploratory analysis of 377,770 singleton live births in the state of New Mexico from 1991-2005. Gestational age of less than 37 weeks was defined as PTB. The …
