ABSTRACT
This paper presents the case of a 28-year-old with a history of chronic pelvic pain suspicious of endometriosis. She underwent a diagnostic laparoscopy and biopsy of lesions along the posterior cul-de-sac and right sidewall near the external iliac artery. Histopathological examination revealed no evidence of endometriosis but did comment on benign lymph node tissue with tattoo-like pigment. These findings correspond to the patient's tattoos located along the lower extremities. It is suspected there was cutaneous tattoo ink migration causing intra-abdominal lymphadenopathy, which visually mimicked endometriosis on diagnostic laparoscopy. Surgeons should become familiar with and recognize this phenomenon, as it can be misleading in the setting of endometriosis and diagnostic laparoscopy. Surgeons undertaking these cases must be able to identify and safely excise abnormal-appearing lesions in many different locations to prevent a missed or delayed diagnosis of endometriosis.
ABSTRACT
Introduction There is a lack of concordance in demographics between dental professionals and their patients. Professional organisations have recognised the necessity of cultural competency training in dental education. This study sought to employ and evaluate a novel intervention in cultural competency training on cross-cultural communication for undergraduate dental students.Material and methods The session employed dyad training, roleplaying, Kleinman's Explanatory Model and introduced the new 'Model for Negotiating Across Cultures', applied to patients' cultures. Learners included 24 first-year and 27 third-year dental students. Evaluation compared pre- and post-intervention responses to the modified Health Belief Attitudes Survey (HBAS). Paired t-tests were conducted to determine difference in pre- and post-intervention scores.Results For first-year students, the mean difference improvement between the pre- and post-intervention surveys for each HBAS domain was statistically significant (p <0.05). For the third-year students, improvement was significant in all domains except for quality (p = 0.083).Discussion Dental students were found to have improved cultural competency scores by the HBAS. Implementation of this educational intervention demonstrates a paradigm that could be implemented for cross-cultural communication.Conclusion The intervention can be utilised as a resource for cross-cultural communication education for dental students and could be expanded for all health professional students.

INTRODUCTION: Obesity is characterized by elevated lipids, insulin resistance and relative hypogonadotropic hypogonadism, reducing fertility and increasing risk of pregnancy complications and birth defects. We termed this phenotype 'Reprometabolic Syndrome' and showed that it can be recapitulated by acute infusions of lipid/insulin into healthy, normal weight, eumenorrheic women. Herein, we examined the broader impact of hyperlipidemia and euglycemic hyperinsulinemia on anterior pituitary trophic hormones and their targets. METHODS: Serum FSH, LH, TSH, growth hormone (GH), prolactin (PRL), thyroid hormones (free T4, total T3), cortisol, IGF-1, adiponectin, leptin and creatinine were measured in a secondary analysis of an interventional crossover study of 12 normal weight cycling women who underwent saline and heparin (control) infusion, or a euglycemic insulin infusion with heparin and Intralipid® (lipid/insulin), between days 2-5 in sequential menstrual cycles. RESULTS: In contrast to the decrease in gonadotropins, FSH and LH, infusion of lipid/insulin had no significant effects on other trophic hormones; TSH, PRL or GH. Thyroid hormones (fT4 and total T3), cortisol, IGF-1, adiponectin and creatinine also did not differ between saline or lipid/insulin infusion conditions. Leptin increased in response to lipid/insulin (p<0.02). CONCLUSION: Acute hyperlipidemia and hyperinsulinemia exerted differential, cell type specific effects on the hypothalamic-pituitary-gonadal, adrenal and thyroid axes. Elucidation of mechanisms underlying the selective modulation of pituitary trophic hormones, in response to changes in diet and metabolism, may facilitate therapeutic intervention in obesity-related neuroendocrine and reproductive dysfunction.

CONTEXT: Obesity, is a state of chronic inflammation, characterized by elevated lipids, insulin resistance and relative hypogonadotropic hypogonadism. We have defined the accompanying decreased Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), ovarian steroids and reduced pituitary response to Gonadotropin-releasing Hormone (GnRH) as Reprometabolic syndrome, a phenotype that can be induced in healthy normal weight women (NWW) by acute infusion of free fatty acids and insulin. OBJECTIVE: To identify potential mediators of insulin and lipid-related reproductive endocrine dysfunction. DESIGN, SETTING, PARTICIPANTS: Secondary analysis of crossover study of eumenorrheic reproductive aged women of normal Body Mass Index (BMI) (<25 kg/m2) at an academic medical center. INTERVENTION: Participants underwent 6-hour infusions of either saline/heparin or insulin plus fatty acids (Intralipid plus heparin), in the early follicular phase of sequential menstrual cycles, in random order. Euglycemia was maintained by glucose infusion. Frequent blood samples were obtained. MAIN OUTCOME MEASURES: Pooled serum from each woman was analyzed for cytokines, interleukins, chemokines, adipokines, Fibroblast Growth Factor-21 (FGF-21) and markers of endoplasmic reticulum (ER) stress (CHOP and GRP78). Wilcoxon signed-rank tests were used to compare results across experimental conditions. RESULTS: Except for Macrophage Inflammatory Protein-1ß (MIP-1ß), no significant differences were observed in serum levels of any of the inflammatory signaling or ER stress markers tested. CONCLUSION: Acute infusion of lipid and insulin, to mimic the metabolic syndrome of obesity, was not associated with an increase in inflammatory markers. These results imply that the endocrine disruption and adverse reproductive outcomes of obesity are not a consequence of the ambient inflammatory environment but may be mediated by direct lipotoxic effects on the hypothalamic-pituitary-ovarian (HPO) axis.
