Altered bone quality, caused by underlying metabolic changes of type 2 diabetes (T2D), has been hypothesized to cause altered bone strength and turnover leading to increased fracture risk in T2D patients. Current understanding about changes in bone turnover markers in T2D patients is mainly based on studies focused on Caucasian men and women. However, Hispanic populations have the highest prevalence of both T2D and osteoporosis in the US.

Functional hypothalamic amenorrhea is a form of chronic anovulation not due to identifiable organic causes with adverse health consequences. A thorough history is paramount in the identification of women with this disorder as it is usually associated with lifestyle factors such as stress, weight loss, and excessive exercise. In this paper, recently published clinical guidelines are reviewed and a series of cases is presented that highlights diagnostic and therapeutic challenges encountered.

The objective of this study was to determine whether TBS is a better clinical tool than traditionally used bone mineral density (BMD) to detect the skeletal deterioration seen in patients with diabetes (DM), patients undergoing oral glucocorticoid (GC) therapy, and patients who are both diabetic and taking steroids (GC + DM). We performed retrospective, cross-sectional study using DXA images of patients who visited UTHealth Department of Internal Medicine DXA clinic in Houston, TX, from May 30, 2014 to May 30, 2016.

Inactivating mutations in the TSC1 and TSC2 genes cause tuberous sclerosis complex, and recent evidence points to a crucial role for these genes in maintaining appropriate ovarian function. The main objective of this study was to estimate reproductive dysfunction in a sample of women with tuberous sclerosis complex.

The hormonal events of puberty, from adrenarche to menarche and beyond, include the secretion of androgens as well as estrogen and P. This normal pubertal process is briefly reviewed and a physiologic role for pubertal androgens proposed. It is further suggested that the hyperandrogenic state we call polycystic ovary syndrome is a maladaptation of the advantageous role of normal pubertal androgens.

Background And Objectives: Hypothyroidism is linked to heart disease and decreased quality of life. Since screening guidelines for the general population are controversial, and physicians use clinical judgment in deciding to order thyroid stimulating hormone (TSH), high-normal levels of TSH pose a dilemma. This study's objective was to compare rates of positive anti-thyroid peroxidase antibodies (antiTPO) tests in persons with high-normal versus low-normal TSH levels.

Anovulatory infertility is common in polycystic ovary syndrome (PCOS). Clinicians who provide first-line treatment have to decide how best to induce ovulation with the desired outcome of live birth, a decision often complicated by the phenotypic heterogeneity of PCOS. could a new livebirth prediction model of different ovulation induction methods developed from basic clinical parameters help select infertility treatments?

The management of polycystic ovary syndrome (PCOS) usually spans a woman's reproductive years. While the treatment of symptoms is a primary concern, given its long-term nature, the benefits and potential risks need to be assessed and balanced. The variability of presentation coupled with the phenotypic diversity of this patient population, requires the individualization of treatment to each patient.

Polycystic ovary syndrome (PCOS) is an extremely common endocrine disorder affecting young women, with the potential for both reproductive and non-reproductive adverse outcomes. While oligomenorrhea, hyperandrogenism, and cystic ovarian morphology are recognized characteristics of this syndrome, the origin of these disturbances is not always apparent. During normal growth and development, adrenarche, the prepubertal onset of adrenal androgen secretion, results phenotypically in pubarche.

Endocrine disorders, in particular, thyroid disorders, are common in pregnancy. The endocrine adaptation to pregnancy, need for adequate iodine supplementation, and thyroxine replacement are presented. In addition, autoimmune diseases of the thyroid and pituitary that may occur subsequent to the immune changes of pregnancy and the postpartum period are discussed.
