After a short review of impotence, the definitions of erectants and aphrodisiacs are presented. The Authors propose division of arthropods according to the places of effect. The description of particular arthropods with their pictures and nomenclature, is followed by certain or probable mechanisms of achieving the aphrodisiac and sometimes toxic effect, that were available in the literature since 1929 till nowadays.We mention the most usual locations, mainly in Asia, where they are found and consumed, but also, we describe the manner of preparing and intake. The review includes the following arthropods: lobster, Arizona bark scorpion, deathstalker, banana spider, Mediterranean black widow, Burmeister's triatoma, giant water bug, diving-beetle, Korean bug, diaclina, flannel moth, Spanish fly, migratory locust, red wood ant and honeybee.

INTRODUCTION: In-hospital mortality of acute aortic type III dissection ranged about 12%. Complicated dissections represent about 18% of all cases, and require open surgery or TEVAR. More morphological predictors of in hospital mortality are needed to differentiate patients who should be selected for immediate, surgical or endovascular intervention.; METHODS: From January 2009 to December 2014, 74 patients with acute aortic type III dissection were enrolled at Clinic of Vascular and Endovascular Surgery in Belgrade Serbia and retrospectively analyzed. Every MSCT was observed in regard to morphologic characteristics of dissection.; RESULTS: By analyzing morphologic parameters in patients between survival and non-survival group only localization of intimal tear showed statistical significance (p=0,020). The size of the intimal tear didn't reach statistical significance with the tendency of doing so in a larger sample of patients (p=0,063) with the cut-off value of 9.55mm. The shape of the true lumen was on the border of statistical significance (p=0,053).; CONCLUSION: Inner curvature intimal tear localization, huge intimal tear as well as elliptic shape of the true lumen together should raise awareness to a subgroup at risk for in hospital mortality. More liberal endovascular treatment in this subgroup of patients is advocated.

OBJECTIVE: Thyroid disease is the second most common endocrine condition in women of childbearing age. Thyroid hormones are involved in control of menstrual cycle and in achieving fertility affecting the actions of folliclestimulating hormone and luteinizing hormone on steroid biosynthesis by specific triiodothyronine sites on oocytes; therefore, affect all aspects of reproduction. It remains controversial if pregnant women should be screened for thyroid dysfunction. Purpose of this review was to examine recent studies on the assessment of thyroid dysfunction in pregnancy, its treatment and newly perspective of thyroid autoimmunity in pregnant euthyroid women in achieving fertility. METHODS: An electronic search was conducted using the internet medical databases: Medline/PubMed, EMBASE, EBSCO, and the Cochrane library. RESULTS: Thyroid gland faces great challenge in pregnancy when many hormonal changes occur. Precondition for normal follicular development and ovulation is pulsate gonadothropin realizing hormone secretion. Thyroid dysfunction in pregnancy is classified as forms of hypothyroidism (positivity of thyroid autoantibody, isolated hypothyroidism, and subclinical or overt hypothyroidism), hyperthyroidism, and autoimmune disease, but also thyroid nodules and cancer, iodine insufficiency and postpartum thyroiditis. These conditions can cause adverse effects on mother and fetus including pregnancy loss, gestational hypertension, or pre-eclampsia, pre-term delivery, low birth weight, placental abruption and postpartum hemorrhage. There is an evidence that thyroid autoimmunity, in thyroid dysfunction adversely affects conception and pregnancy outcomes, but it is unclear what impact has isolated eumetabolic thyroid autoimmunity in achieving fertility, especially in women undergoing in vitro fertilization. Treatment of euthyroid pregnant women with positive thyroid peroxides antibodies is still controverse, but not few studies show that levothyroxine substitution is able to lower the chance of miscarriage and premature delivery. CONCLUSIONS: Further randomized trials are needed to expand our knowledge of physiologic changes in thyroid function during the pregnancy and to reveal mechanisms by which thyroid autoimmunity in euthyroid women affect fertility, especially the success of assisted reproductive technology in achieving the same and validity of levothyroxine administration in thyroid autoimmunity positive women.
