Hepatic encephalopathy (HE) remains a diagnosis of exclusion due to the lack of specific signs and symptoms. Refractory HE is an uncommon but serious condition that requires the search of hidden precipitating events (i.e., portosystemic shunt) and alternative diagnosis. Hypothyroidism shares clinical manifestations with HE and is usually considered within the differential diagnosis of HE. Here, we describe a patient with refractory HE who presented a large portosystemic shunt and post-ablative hypothyroidism...

In the desert gerbil Gerbillus tarabuli (Thomas, 1902), cortisol is the main glucocorticosteroid produced by the adrenal glands. Plasma cortisol concentrations show highest values when testosterone is reduced and lowest values during the breeding season which occurs from early winter to late spring. In order to specify the implication of testicular androgens in these corticosteroid seasonal variations we investigated the effects induced by gonadectomy performed during the breeding season on the pituitary adrenal axis...

BACKGROUND: Cirrhotic patients are susceptible to sepsis and critical illness-related corticosteroid insufficiency (CIRCI). Dehydroepiandrosterone sulfate (DHEAS) is a corticotropin-dependent adrenal androgen, which has immunostimulating and antiglucocorticoid effects. Considering the synchronized synthesis of cortisol and DHEAS and their opposing effects to each other, investigators have proposed measuring these two hormones as a ratio. Severe sepsis has been associated with low DHEAS, especially relative to high cortisol...

BACKGROUND: The proportion of newborns recalled during neonatal screening programs for congenital hypothyroidism (CH) varies substantially by country and may be higher in settings where povodine iodine (PVP-I) is used during delivery. We assessed this hypothesis by substituting PVP-I for chlorhexidine (CHL) and evaluated the reduction in the recall rate of the Irainian newborn screening program. METHODS: This study investigated 2282 neonates of mothers admitted to a local hospital for delivery between December 2012 and October 2013...

INTRODUCTION AND OBJECTIVES: Radioguided surgery is a minimally invasive surgical technique for the treatment of primary hyperparathyroidism. The goals of our study were to evaluate the rate of success and compare the results with intraoperative histological analysis. METHODS: We retrospectively studied 84 patients with primary parathyroidism who had undergone radioguided surgery. All the patients had a positive parathyroid scintigraphy prior to surgery. An intravenous injection of Tc-99m sestamibi was administered before surgery, and radioguided location of the pathologic parathyroid tissue was performed using an intraoperative gamma probe, applying the "20% rule"...

REVIEW
Judith Korb, Xavier Belles
Termites are social Dictyoptera that evolved eusociality independently from social Hymenoptera. They are characterized by unique developmental plasticity that is the basis of caste differentiation and social organization. As developmental plasticity is a result of endocrine regulation, in order to understand the evolution of termite sociality it is helpful to compare the endocrine underpinning of development between termites and cockroaches. Nijhout and Wheeler (1982) proposed that varying JH titers determine caste differentiation in termites...

Human placental growth hormone (PGH), encoded by the growth hormone (GH) variant gene on chromosome 17, is expressed in the syncytiotrophoblast and extravillous cytotrophoblast layers of the human placenta. Its maternal serum levels increase throughout pregnancy, and gradually replaces the pulsatile secreted pituitary GH. PGH is also detectable in cord blood and in the amniotic fluid. This placental-origin hormone stimulates glyconeogenesis, lipolysis and anabolism in maternal organs, and influences fetal growth, placental development and maternal adaptation to pregnancy...

Natural aging brings reduced production of growth and sex hormones, beginning in middle age, with noticeable physiologic changes by the sixth or seventh decade of life: reduced muscle mass, energy, and exercise capacity and alterations in sexual function. Hormones and hormone precursors have been investigated to delay changes in body composition, strength, and physical and cognitive function. Menopausal hormone therapy is effective for vasomotor and genitourinary symptoms. Testosterone is effective in men with hypogonadism and declines in physiologic function...

BACKGROUND: Copper-containing contraceptive devices may deposit copper ions in the endometrium, resulting in implantation failure. The deposition of copper ions in many organs has been reported in patients with untreated Wilson's disease. Since these patients sometimes exhibit subfertility and/or early pregnancy loss, copper ions were also considered to accumulate in the uterine endometrium. Wilson's disease patients treated with zinc successfully delivered babies because zinc interfered with the absorption of copper from the gastrointestinal tract...

<br>Hypophysitis is a relatively rare disease that exerts a strong autoimmune component encompassing different aetiologies. Immunomodulatory drugs, such as interferon-α, are known to rarely induce hypophysitis. In recent years a large number of new biological and immunomodulatory agents have been introduced into clinical practice. Although immune suppressing agents used for the treatment of autoimmune disorders only rarely are associated with hypophysitis, it is commonly encountered with immunomodulatory agents used for the treatment of cancer...

Disturbances of the steroidogenesis or altered peripheral metabolism of steroids may result in severe clinical manifestations. Therefore, prompt diagnosis and initiation of medical treatment are desirable. The diagnostics of disorders of steroid hormone production, metabolism, and action have been previously based on immunoassay tests. However, in a modern medical laboratory, due to low accuracy of immunoassays, this technique is continuously replaced by chromatographic separation methods coupled to mass spectrometric detection systems...

BACKGROUND: Klinefelter's syndrome is a sex chromosome abnormality affecting approximately 1 in 1000 men. There have been suggestions that it is associated with a higher than average prevalence of sexual offending but to what extent does research evidence support this assertion? AIMS: This study aimed to conduct a systematic review of published research to establish the prevalence of sexual offending in men with Klinefelter's syndrome. METHOD: The databases MEDLINE, PsycINFO and EMBASE were searched from inception until 31 December 2016 by using a range of terms for Klinefelter's syndrome and for sexual offending...

WHAT IS KNOWN AND OBJECTIVE: Several studies have reported that itraconazole-induced inhibition of vincristine (VCR) metabolism might result in neurological impairment and syndrome of inappropriate antidiuretic hormone (SIADH). However, there are few reports concerning adverse drug reactions (ADRs) resulting from concomitant use of vindesine (VDS) and itraconazole. Here, we report the first case of adverse drug interactions (ADIs) between itraconazole and VDS in a Chinese child with acute lymphocytic leukaemia (ALL)...

In previous centuries many women did not even live until their menopause years due to poor economic conditions, deficiencies of medicine, epidemics and wars. Nowadays in the developed countries, people live until they are 75-80 years old, and with the expansion of average age, the number of people affected by menopause and the years spent in that state increase. Nowadays women spend one third of their lives in the menopausal stage. The only effective way to treat unpleasant symptoms for centuries was with the use of herbs, and the knowledge about them spread through oral tradition...

BACKGROUND: It is thought that growth hormone (GH) therapy success depends on the patient's adherence to their treatment regimen, but an optimal approach to improve adherence has not yet been established. METHODS: To evaluate the effect of patient choice of a GH device on adherence to GH therapy, we carried out a retrospective longitudinal study of 46 GH deficient patients (24 boys, mean age of commencing GH therapy: 7.70±3.12 years) treated with recombinant GH therapy for 3 years, either with or without patient choice (n=28, 18, respectively)...
