Premature Ovarian Failure: Clinical Presentation and Treatment

Premature ovarian failure is a devastating diagnosis for reproductive-aged women. The diagnosis is relatively easy. However, it has serious health consequences, including psychological distress, infertility, osteoporosis, autoimmune disorders, ischemic heart disease, and increased risk for mortality. Management should be initiated immediately to prevent long-term consequences. Estrogen therapy is the mainstay of management. Postmenopausal estrogen therapy studies should not be used to determine the risks of treatment in these young women.

Florid endometriosis in a postmenopausal woman

OBJECTIVE To report a case of florid endometriosis. DESIGN Case report. SETTING University hospital. PATIENT(S) A 53-year-old postmenopausal woman with a 10-cm retroperitoneal mass comprised of endometriosis causing hydroureteronephrosis and loss of ipsilateral kidney function. INTERVENTION(S) The patient underwent exploratory laparotomy with extensive lysis of adhesions, right nephrectomy, radical resection of the retroperitoneal mass including partial resection of the psoas muscle, dissection from the inferior vena cava, and resection of distal ileum, cecum, and appendix with a primary ileoascending colon reanastomosis. MAIN OUTCOME MEASURE(S) Postoperative symptom resolution. RESULT(S) The patient had widespread adhesive disease with a primary retroperitoneal endometriotic mass and a secondary mass involving the small bowel mesentery. Endometriomas were found in the right kidney and right distal ureter. Additional endometriotic implants were found at the right common iliac bifurcation, appendix, and in multiple mesenteric nodules. No residual ovarian tissue was identified, and preoperative FSH and estrogen (E) levels indicated no evidence of an ovarian remnant. CONCLUSION(S) Severe endometriosis caused ipsilateral renal failure despite postmenopausal levels of E and FSH, supporting the theory that endometriotic implants may have an autocrine function involving E biosynthesis or may respond to hormone production in adipose tissue.

Implantation failure of endometrial origin: it is not pathology, but our failure to synchronize the developing embryo with a receptive endometrium

Repeated implantation failure (RIF) is an intriguing, massive failure of reproductive treatment in otherwise healthy women leading to the introduction of empirical adjuvant interventions that are costly, inefficient, and frustrating for our patients. In this article, we will try to convince the readers that RIF is neither a stigma nor a mysterious pathology but rather our failure to diagnose and properly synchronize the euploid blastocyst with the patients personalized window of implantation.

Perioperative evaluation in Herlyn-Werner-Wunderlich syndrome.

BACKGROUND: Herlyn-Werner-Wunderlich syndrome is defined by uterine didelphys, obstructed hemivagina, and ipsilateral renal agenesis. We report the presentation, radiographic findings, and outcomes of three patients with Herlyn-Werner-Wunderlich syndrome who underwent surgical management at a tertiary care academic medical center. CASES: Two patients were diagnosed by magnetic resonance imaging and one by ultrasonography. All three underwent successful transvaginal septoplasty and drainage of the hematocolpos and hematometra. One required septoplasty revision with temporary vaginal stent placement. CONCLUSION: Herlyn-Werner-Wunderlich syndrome is a rare condition. The most urgent concern is the obstruction of menstrual effluent. Unlike an isolated transverse vaginal septum, the vaginal septum with Herlyn-Werner-Wunderlich syndrome is parallel to the patent vaginal canal, less pliable, and closer to the cervix. These anatomical differences result in pronounced distortion with significant diagnostic and surgical challenges.

VCAM-1 on peritoneum and α4β1 integrin in endometrium and their implications in endometriosis.

The objective of the study is to investigate vascular cellular adhesion molecule-1 (VCAM-1) expression on peritoneal mesothelial cells and &agr;4&bgr;1 integrin on eutopic endometrium as possible mechanisms in the pathogenesis of endometriosis. It is a case-control study carried out at an academic medical center. Participants are patients with (n=9) and without (n=15) endometriosis. The main outcome measures included VCAM-1 expression on peritoneal mesothelial cells and &agr;4&bgr;1 expression on eutopic endometrium using immunohistochemistry and flow cytometry, respectively. Patients with endometriosis were more likely to express VCAM-1 on peritoneal mesothelial cells, both in areas with and without macroscopic disease, compared with patients without endometriosis (9/9 vs. 3/15, P<0.001). No differences were found between cases and controls in regards to eutopic endometrial expression of &agr;4&bgr;1 integrin. The presence of VCAM-1 on peritoneal mesothelial cells is associated with endometriosis. This field effect, in addition to the similarity found with regards to the expression of &agr;4&bgr;1 integrin in eutopic endometrium between cases and controls, may implicate the expression of VCAM-1 in the peritoneum, and not changes in the eutopic endometrium, as a contributor to the pathogenesis of endometriosis.

Novel lean type 2 diabetic rat model using gestational low-protein programming.

BACKGROUND Type 2 diabetes (T2D) in lean individuals is not well studied and up to 26% of diabetes occurs in these individuals. Although the cause is not well understood, it has been primarily attributed to nutritional issues during early development. OBJECTIVE Our objective was to develop a lean T2D model using gestational low-protein (LP) programming. STUDY DESIGN Pregnant rats were fed control (20% protein) or isocaloric LP (6%) diet from gestational day 4 until delivery. Standard diet was given to dams after delivery and to pups after weaning. Glucose tolerance test was done at 2, 4, and 6 months of age. Magnetic resonance imaging of body fat for females was done at 4 months. Rats were sacrificed at 4 and 8 months of age and their perigonadal, perirenal, inguinal, and brown fat were weighed and expressed relative to their body weight. Euglycemic-hyperinsulinemic clamp was done around 6 months of age. RESULTS Male and female offspring exposed to a LP diet during gestation developed glucose intolerance and insulin resistance (IR). Further, glucose intolerance progressed with increasing age and occurred earlier and was more severe in females when compared to males. Euglycemic-hyperinsulinemic clamp showed whole body IR in both sexes, with females demonstrating increased IR compared to males. LP females showed a 4.5-fold increase in IR while males showed a 2.5-fold increase when compared to their respective controls. Data from magnetic resonance imaging on female offspring showed no difference in the subcutaneous, inguinal, and visceral fat content. We were able to validate this observation by sacrificing the rats at 4 and 8 months and measuring total body fat content. This showed no differences in body fat content between control and LP offspring in either males or females. Additionally, diabetic rats had a similar body mass index to that of the controls. CONCLUSION LP gestational programming produces a progressively worsening T2D model in rats with a lean phenotype without obesity.

Pelvic pedicled omental flaps and autologous free omental grafts in a rabbit model

BackgroundThere is a need to identify an inexpensive, effective method to prevent postoperative adhesion formation. The objective of this study was to create a novel model for studying omentum as a pelvic adhesion barrier.Randomized, prospective, controlled surgical intervention with serial follow-up in 16 female rabbits at a University-based Center for Comparative Medicine. Interventions included bilateral hysterotomy incision and repair. The left hysterotomy was randomized into coverage with an omental flap or graft; the right hysterotomy remained uncovered. Adhesions were scored via laparoscopy on postoperative days 2, 4, 8, and 12; postmortem evaluation and scoring took place on postoperative day 16. Statistical tests consisted of Kappa tests of agreement between adhesion scorers and Kruskal-Wallis nonparametric tests for the comparison of adhesion scores by intervention arm and by uterine horn.ResultsAll omental flaps and grafts survived. The only significant difference in mean adhesion scores was seen in non-hysterotomy-associated adhesions, where grafts had a lower score than flaps (p = 0.03).ConclusionsSurvival of all omental flaps and grafts demonstrates that this is a practical model for studying omentum as a pelvic adhesion barrier. Determining the efficacy of omentum as a pelvic adhesion barrier will require further investigation.

A Novel Ultrasound-Guided Technique for Hysteroscopic Adhesiolysis in High-Risk Patients: Ultrasound-Guided Hysteroscopic Adhesiolysis

Hysteroscopy is a common gynecologic surgical procedure. Certain diagnoses, notably intrauterine adhesions and cervical stenosis, make hysteroscopy more complicated because of an increased likelihood of complications. Three patients, 1 with cervical stenosis and 2 with Asherman syndrome, underwent ultrasound (US)‐guided adhesiolysis. Access to the uterine cavity was obtained by either direct balloon‐aided dilation or the US‐guided Seldinger technique, followed by balloon‐aided dilation to enter the endometrial cavity and disrupt intrauterine/intracervical adhesions. In this case series, we describe a novel approach of using US‐guided balloon dilation to safely and effectively treat intrauterine adhesions and to decrease the risk of perforation.

Cyanotic congenital heart disease following fertility treatments in the United States from 2011 to 2014

Objective To examine the risk for cyanotic congenital heart diseases (CCHDs) among live births in the USA, resulting from various forms of infertility treatments. Methods This study is a cross-sectional analysis of live births in the USA from 2011 to 2014. Infertility treatments are categorised into two of the following groups on birth certificates: assisted reproductive technology (ART) fertility treatment (surgical egg removal; eg, in vitro fertilisation and gamete intrafallopian transfer) and non-ART fertility treatment (eg, medical treatment and intrauterine insemination). We compared the risk for CCHD in ART and non-ART fertility treatment groups with those infants whose mothers received no documented fertility treatment and were naturally conceived (NC). Results Among 14 242 267 live births from 2011 to 2014, a total of 101 494 live births were in the ART and 81 242 resulted from non-ART fertility treatments. CCHD prevalence in ART, non-ART and NC groups were 393/100 892 (0.39%), 210/80 884 (0.26%) and 10 749/14 020 749 (0.08%), respectively. As compared with naturally conceiving infants, risk for CCHD was significantly higher among infants born in ART (adjusted relative risk (aRR) 2.4, 95% CI 2.1 to 2.7) and non-ART fertility treatment groups (aRR 1.9, 95% CI 1.6 to 2.2). Absolute risk increase in CCHD due to ART and non-ART treatments were 0.03% and 0.02%, respectively. A similar pattern was observed when the analysis was restricted to twins, newborns with birth weights under 1500 g and gestational age of less than 32 weeks. Conclusions Our findings suggest an increased risk for CCHD in infants conceived after all types of infertility treatment.

Folate treatment partially reverses gestational low protein diet induced glucose intolerance and the magnitude of reversal is age and sex dependent

OBJECTIVES Gestational low-protein (LP) programming causes glucose intolerance (GI) and insulin resistance (IR) in adult offspring. Folate supplementation has been shown to rescue the offspring from various programming effects. The aim of this study was to investigate whether folate supplementation during pregnancy reverses LP-induced GI and IR. METHODS Pregnant rats were fed control (20% protein), isocaloric low-protein (LP, 6%) or LP with 5 mg/kg folate (LPF) diets from gestational day 4 to delivery. The control diet was given during lactation and to pups after weaning. Glucose tolerance test was done at 1, 2, and 3 mo of age followed by euglycemic-hyperinsulinemic clamp at 4 mo. Rats were sacrificed at 4 mo and their gonadal, renal, inguinal, brown fat, and pancreas were weighed and expressed relative to their body weight. RESULTS LP- and LPF-fed dams showed similar weight loss during late pregnancy after decreased feed intake. Both LP and LPF pups were smaller at birth but their weights caught up like that of controls by 3 mo. In males, folate supplementation reduced LP-induced GI at 2 mo (glucose area under the curve [AUC]: 1940 mmol/L × 180 min in LP, 1629 mmol/L × 180 min in LPF, and 1653 mmol/L × 180 min in controls; P <0.05, LP versus control and P <0.01, LP versus LPF) but the effect diminished at 3 mo. In females, folate reduced GI at 1 mo (glucose AUC: 1406 mmol/L × 180 min in LP, 1264 mmol/L × 180 min in LPF, and 1281 mmol/L × 180 min in controls; P <0.05, LP versus control and LP versus LPF) but had no effect at 2 and 3 mo. Interestingly, the LPF group had higher pancreatic weights than other groups, suggesting that folate helps in pancreatic development enabling the LPF rats to produce/secrete more insulin to maintain euglycemia. Euglycemic-hyperinsulinemic clamp shows both LP and LPF are insulin resistant compared with controls by 4 mo with LPF more severe than LP in males. Interestingly, females were more insulin resistant than males. CONCLUSIONS Folate treatment partially reverses LP-induced GI and the magnitude of reversal is age and sex dependent. Furthermore, folate treatment does not reverse IR in either sex but makes it worse in males at 4 mo. The present study demonstrated that folate treatment is not sufficient to rescue the LP programming effects.
